     FIELD 
     The present disclosure relates generally to computer user interfaces, and more specifically to techniques for managing health monitoring. 
     BACKGROUND 
     Monitoring health, such as heart health using heart rhythm and heart rate information, using electronic devices is a convenient and effective method of providing and maintaining awareness of one&#39;s health. Using electronic devices enable a user to quickly and easily capture biometric information used to monitor the user&#39;s health. 
     BRIEF SUMMARY 
     Some techniques for managing health monitoring using electronic devices, however, are generally cumbersome and inefficient. For example, some existing techniques use a complex and time-consuming user interface, which may include multiple key presses or keystrokes. Existing techniques require more time than necessary, wasting user time and device energy. This latter consideration is particularly important in battery-operated devices. 
     Accordingly, the present technique provides electronic devices with faster, more efficient methods and interfaces for managing health monitoring. Such methods and interfaces optionally complement or replace other methods for managing health monitoring. Such methods and interfaces reduce the cognitive burden on a user and produce a more efficient human-machine interface. For battery-operated computing devices, such methods and interfaces conserve power and increase the time between battery charges. Such methods and interfaces enable a user to quickly and easily capture health information (thereby also incentivizing the user to frequently monitor his or her health) and to conveniently view and manage recorded health information (thereby raising awareness of the user&#39;s current health status to the user).

     DESCRIPTION OF EMBODIMENTS 
     The following description sets forth exemplary methods, parameters, and the like. It should be recognized, however, that such description is not intended as a limitation on the scope of the present disclosure but is instead provided as a description of exemplary embodiments. 
     There is a need for electronic devices that provide efficient methods and interfaces for managing health monitoring. For example, there is a need for electronic devices that quickly and conveniently capture biometric information from a user to enable the user to easily monitor his or her health. For another example, there is a need for electronic devices that manage captured biometric information from the user such that the user can easily and conveniently access and view monitoring and evaluation results. For another example, there is a need for electronic devices that efficiently present evaluation results to the user to enable the user to easily understand and properly respond to the results. Such techniques can reduce the cognitive burden on a user who accesses health monitoring features, thereby enhancing productivity. Further, such techniques can reduce processor and battery power otherwise wasted on redundant user inputs.

     Although the following description uses terms “first,” “second,” etc. to describe various elements, these elements should not be limited by the terms. These terms are only used to distinguish one element from another. For example, a first touch could be termed a second touch, and, similarly, a second touch could be termed a first touch, without departing from the scope of the various described embodiments. The first touch and the second touch are both touches, but they are not the same touch. 
     The terminology used in the description of the various described embodiments herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used in the description of the various described embodiments and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term “and/or” as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. It will be further understood that the terms “includes,” “including,” “comprises,” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. 
     The term “if” is, optionally, construed to mean “when” or “upon” or “in response to determining” or “in response to detecting,” depending on the context. Similarly, the phrase “if it is determined” or “if [a stated condition or event] is detected” is, optionally, construed to mean “upon determining” or “in response to determining” or “upon detecting [the stated condition or event]” or “in response to detecting [the stated condition or event],” depending on the context. 
     Embodiments of electronic devices, user interfaces for such devices, and associated processes for using such devices are described. In some embodiments, the device is a portable communications device, such as a mobile telephone, that also contains other functions, such as PDA and/or music player functions. Exemplary embodiments of portable multifunction devices include, without limitation, the iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, Calif. Other portable electronic devices, such as laptops or tablet computers with touch-sensitive surfaces (e.g., touch screen displays and/or touchpads), are, optionally, used. It should also be understood that, in some embodiments, the device is not a portable communications device, but is a desktop computer with a touch-sensitive surface (e.g., a touch screen display and/or a touchpad). 
     In the discussion that follows, an electronic device that includes a display and a touch-sensitive surface is described. It should be understood, however, that the electronic device optionally includes one or more other physical user-interface devices, such as a physical keyboard, a mouse, and/or a joystick. 
     The device typically supports a variety of applications, such as one or more of the following: a drawing application, a presentation application, a word processing application, a website creation application, a disk authoring application, a spreadsheet application, a gaming application, a telephone application, a video conferencing application, an e-mail application, an instant messaging application, a workout support application, a photo management application, a digital camera application, a digital video camera application, a web browsing application, a digital music player application, and/or a digital video player application. 
     The various applications that are executed on the device optionally use at least one common physical user-interface device, such as the touch-sensitive surface. One or more functions of the touch-sensitive surface as well as corresponding information displayed on the device are, optionally, adjusted and/or varied from one application to the next and/or within a respective application. In this way, a common physical architecture (such as the touch-sensitive surface) of the device optionally supports the variety of applications with user interfaces that are intuitive and transparent to the user. 
     Attention is now directed toward embodiments of portable devices with touch-sensitive displays.  FIG. 1A  is a block diagram illustrating portable multifunction device  100  with touch-sensitive display system  112  in accordance with some embodiments. Touch-sensitive display  112  is sometimes called a “touch screen” for convenience and is sometimes known as or called a “touch-sensitive display system.” Device  100  includes memory  102  (which optionally includes one or more computer-readable storage mediums), memory controller  122 , one or more processing units (CPUs)  120 , peripherals interface  118 , RF circuitry  108 , audio circuitry  110 , speaker  111 , microphone  113 , input/output (I/O) subsystem  106 , other input control devices  116 , and external port  124 . Device  100  optionally includes one or more optical sensors  164 . Device  100  optionally includes one or more contact intensity sensors  165  for detecting intensity of contacts on device  100  (e.g., a touch-sensitive surface such as touch-sensitive display system  112  of device  100 ). Device  100  optionally includes one or more tactile output generators  167  for generating tactile outputs on device  100  (e.g., generating tactile outputs on a touch-sensitive surface such as touch-sensitive display system  112  of device  100  or touchpad  355  of device  300 ). These components optionally communicate over one or more communication buses or signal lines  103 . 
     As used in the specification and claims, the term “intensity” of a contact on a touch-sensitive surface refers to the force or pressure (force per unit area) of a contact (e.g., a finger contact) on the touch-sensitive surface, or to a substitute (proxy) for the force or pressure of a contact on the touch-sensitive surface. The intensity of a contact has a range of values that includes at least four distinct values and more typically includes hundreds of distinct values (e.g., at least 256). Intensity of a contact is, optionally, determined (or measured) using various approaches and various sensors or combinations of sensors. For example, one or more force sensors underneath or adjacent to the touch-sensitive surface are, optionally, used to measure force at various points on the touch-sensitive surface. In some implementations, force measurements from multiple force sensors are combined (e.g., a weighted average) to determine an estimated force of a contact. Similarly, a pressure-sensitive tip of a stylus is, optionally, used to determine a pressure of the stylus on the touch-sensitive surface. Alternatively, the size of the contact area detected on the touch-sensitive surface and/or changes thereto, the capacitance of the touch-sensitive surface proximate to the contact and/or changes thereto, and/or the resistance of the touch-sensitive surface proximate to the contact and/or changes thereto are, optionally, used as a substitute for the force or pressure of the contact on the touch-sensitive surface. In some implementations, the substitute measurements for contact force or pressure are used directly to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is described in units corresponding to the substitute measurements). In some implementations, the substitute measurements for contact force or pressure are converted to an estimated force or pressure, and the estimated force or pressure is used to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is a pressure threshold measured in units of pressure). Using the intensity of a contact as an attribute of a user input allows for user access to additional device functionality that may otherwise not be accessible by the user on a reduced-size device with limited real estate for displaying affordances (e.g., on a touch-sensitive display) and/or receiving user input (e.g., via a touch-sensitive display, a touch-sensitive surface, or a physical/mechanical control such as a knob or a button). 
     As used in the specification and claims, the term “tactile output” refers to physical displacement of a device relative to a previous position of the device, physical displacement of a component (e.g., a touch-sensitive surface) of a device relative to another component (e.g., housing) of the device, or displacement of the component relative to a center of mass of the device that will be detected by a user with the user&#39;s sense of touch. For example, in situations where the device or the component of the device is in contact with a surface of a user that is sensitive to touch (e.g., a finger, palm, or other part of a user&#39;s hand), the tactile output generated by the physical displacement will be interpreted by the user as a tactile sensation corresponding to a perceived change in physical characteristics of the device or the component of the device. For example, movement of a touch-sensitive surface (e.g., a touch-sensitive display or trackpad) is, optionally, interpreted by the user as a “down click” or “up click” of a physical actuator button. In some cases, a user will feel a tactile sensation such as an “down click” or “up click” even when there is no movement of a physical actuator button associated with the touch-sensitive surface that is physically pressed (e.g., displaced) by the user&#39;s movements. As another example, movement of the touch-sensitive surface is, optionally, interpreted or sensed by the user as “roughness” of the touch-sensitive surface, even when there is no change in smoothness of the touch-sensitive surface. While such interpretations of touch by a user will be subject to the individualized sensory perceptions of the user, there are many sensory perceptions of touch that are common to a large majority of users. Thus, when a tactile output is described as corresponding to a particular sensory perception of a user (e.g., an “up click,” a “down click,” “roughness”), unless otherwise stated, the generated tactile output corresponds to physical displacement of the device or a component thereof that will generate the described sensory perception for a typical (or average) user.

In some embodiments, some or all of the visual output optionally corresponds to user-interface objects. 
     Touch screen  112  has a touch-sensitive surface, sensor, or set of sensors that accepts input from the user based on haptic and/or tactile contact. Touch screen  112  and display controller  156  (along with any associated modules and/or sets of instructions in memory  102 ) detect contact (and any movement or breaking of the contact) on touch screen  112  and convert the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages, or images) that are displayed on touch screen  112 . In an exemplary embodiment, a point of contact between touch screen  112  and the user corresponds to a finger of the user.

No. 6,323,846 (Westerman et al.), U.S. Pat. No. 6,570,557 (Westerman et al.), and/or U.S. Pat. No. 6,677,932 (Westerman), and/or U.S. Patent Publication 2002/0015024A1, each of which is hereby incorporated by reference in its entirety. However, touch screen  112  displays visual output from device  100 , whereas touch-sensitive touchpads do not provide visual output. 
     A touch-sensitive display in some embodiments of touch screen  112  is described in the following applications: (1) U.S. patent application Ser. No. 11/381,313, “Multipoint Touch Surface Controller,” filed May 2, 2006; (2) U.S. patent application Ser. No. 10/840,862, “Multipoint Touchscreen,” filed May 6, 2004; (3) U.S. patent application Ser. No. 10/903,964, “Gestures For Touch Sensitive Input Devices,” filed Jul. 30, 2004; (4) U.S. patent application Ser. No. 11/048,264, “Gestures For Touch Sensitive Input Devices,” filed Jan. 31, 2005; (5) U.S. patent application Ser.

No. 11/228,758, “Virtual Input Device Placement On A Touch Screen User Interface,” filed Sep. 16, 2005; (7) U.S. patent application Ser. No. 11/228,700, “Operation Of A Computer With A Touch Screen Interface,” filed Sep. 16, 2005; (8) U.S. patent application Ser. No. 11/228,737, “Activating Virtual Keys Of A Touch-Screen Virtual Keyboard,” filed Sep. 16, 2005; and (9) U.S. patent application Ser. No. 11/367,749, “Multi-Functional Hand-Held Device,” filed Mar. 3, 2006. All of these applications are incorporated by reference herein in their entirety. 
     Touch screen  112  optionally has a video resolution in excess of 100 dpi. In some embodiments, the touch screen has a video resolution of approximately 160 dpi. The user optionally makes contact with touch screen  112  using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work primarily with finger-based contacts and gestures, which can be less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user. 
     In some embodiments, in addition to the touch screen, device  100  optionally includes a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad is, optionally, a touch-sensitive surface that is separate from touch screen  112  or an extension of the touch-sensitive surface formed by the touch screen. 
     Device  100  also includes power system  162  for powering the various components. Power system  162  optionally includes a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices.

In some embodiments, an optical sensor is located on the back of device  100 , opposite touch screen display  112  on the front of the device so that the touch screen display is enabled for use as a viewfinder for still and/or video image acquisition. In some embodiments, an optical sensor is located on the front of the device so that the user&#39;s image is, optionally, obtained for video conferencing while the user views the other video conference participants on the touch screen display. In some embodiments, the position of optical sensor  164  can be changed by the user (e.g., by rotating the lens and the sensor in the device housing) so that a single optical sensor  164  is used along with the touch screen display for both video conferencing and still and/or video image acquisition. 
     Device  100  optionally also includes one or more contact intensity sensors  165 .  FIG. 1A  shows a contact intensity sensor coupled to intensity sensor controller  159  in I/O subsystem  106 . Contact intensity sensor  165  optionally includes one or more piezoresistive strain gauges, capacitive force sensors, electric force sensors, piezoelectric force sensors, optical force sensors, capacitive touch-sensitive surfaces, or other intensity sensors (e.g., sensors used to measure the force (or pressure) of a contact on a touch-sensitive surface). Contact intensity sensor  165  receives contact intensity information (e.g., pressure information or a proxy for pressure information) from the environment. In some embodiments, at least one contact intensity sensor is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system  112 ). In some embodiments, at least one contact intensity sensor is located on the back of device  100 , opposite touch screen display  112 , which is located on the front of device  100 . 
     Device  100  optionally also includes one or more proximity sensors  166 .  FIG. 1A  shows proximity sensor  166  coupled to peripherals interface  118 . Alternately, proximity sensor  166  is, optionally, coupled to input controller  160  in I/O subsystem  106 . Proximity sensor  166  optionally performs as described in U.S. patent application Ser. No. 11/241,839, “Proximity Detector In Handheld Device”; Ser. No. 11/240,788, “Proximity Detector In Handheld Device”; Ser. No. 11/620,702, “Using Ambient Light Sensor To Augment Proximity Sensor Output”; Ser. No. 11/586,862, “Automated Response To And Sensing Of User Activity In Portable Devices”; and Ser. No. 11/638,251, “Methods And Systems For Automatic Configuration Of Peripherals,” which are hereby incorporated by reference in their entirety. In some embodiments, the proximity sensor turns off and disables touch screen  112  when the multifunction device is placed near the user&#39;s ear (e.g., when the user is making a phone call). 
     Device  100  optionally also includes one or more tactile output generators  167 .  FIG. 1A  shows a tactile output generator coupled to haptic feedback controller  161  in I/O subsystem  106 . Tactile output generator  167  optionally includes one or more electroacoustic devices such as speakers or other audio components and/or electromechanical devices that convert energy into linear motion such as a motor, solenoid, electroactive polymer, piezoelectric actuator, electrostatic actuator, or other tactile output generating component (e.g., a component that converts electrical signals into tactile outputs on the device). Contact intensity sensor  165  receives tactile feedback generation instructions from haptic feedback module  133  and generates tactile outputs on device  100  that are capable of being sensed by a user of device  100 . In some embodiments, at least one tactile output generator is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system  112 ) and, optionally, generates a tactile output by moving the touch-sensitive surface vertically (e.g., in/out of a surface of device  100 ) or laterally (e.g., back and forth in the same plane as a surface of device  100 ). In some embodiments, at least one tactile output generator sensor is located on the back of device  100 , opposite touch screen display  112 , which is located on the front of device  100 . 
     Device  100  optionally also includes one or more accelerometers  168 .  FIG. 1A  shows accelerometer  168  coupled to peripherals interface  118 . Alternately, accelerometer  168  is, optionally, coupled to an input controller  160  in I/O subsystem  106 . Accelerometer  168  optionally performs as described in U.S. Patent Publication No. 20050190059, “Acceleration-based Theft Detection System for Portable Electronic Devices,” and U.S. Patent Publication No. 20060017692, “Methods And Apparatuses For Operating A Portable Device Based On An Accelerometer,” both of which are incorporated by reference herein in their entirety. In some embodiments, information is displayed on the touch screen display in a portrait view or a landscape view based on an analysis of data received from the one or more accelerometers. Device  100  optionally includes, in addition to accelerometer(s)  168 , a magnetometer (not shown) and a GPS (or GLONASS or other global navigation system) receiver (not shown) for obtaining information concerning the location and orientation (e.g., portrait or landscape) of device  100 . 
     In some embodiments, the software components stored in memory  102  include operating system  126 , communication module (or set of instructions)  128 , contact/motion module (or set of instructions)  130 , graphics module (or set of instructions)  132 , text input module (or set of instructions)  134 , Global Positioning System (GPS) module (or set of instructions)  135 , and applications (or sets of instructions)  136 . Furthermore, in some embodiments, memory  102  ( FIG. 1A ) or  370  ( FIG. 3 ) stores device/global internal state  157 , as shown in  FIGS. 1A and 3 . Device/global internal state  157  includes one or more of: active application state, indicating which applications, if any, are currently active; display state, indicating what applications, views or other information occupy various regions of touch screen display  112 ; sensor state, including information obtained from the device&#39;s various sensors and input control devices  116 ; and location information concerning the device&#39;s location and/or attitude. 
     Operating system  126  (e.g., Darwin, RTXC, LINUX, UNIX, OS X, iOS, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components. 
     Communication module  128  facilitates communication with other devices over one or more external ports  124  and also includes various software components for handling data received by RF circuitry  108  and/or external port  124 . External port  124  (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector that is the same as, or similar to and/or compatible with, the 30-pin connector used on iPod® (trademark of Apple Inc.) devices. 
     Contact/motion module  130  optionally detects contact with touch screen  112  (in conjunction with display controller  156 ) and other touch-sensitive devices (e.g., a touchpad or physical click wheel). Contact/motion module  130  includes various software components for performing various operations related to detection of contact, such as determining if contact has occurred (e.g., detecting a finger-down event), determining an intensity of the contact (e.g., the force or pressure of the contact or a substitute for the force or pressure of the contact), determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more finger-dragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). Contact/motion module  130  receives contact data from the touch-sensitive surface. Determining movement of the point of contact, which is represented by a series of contact data, optionally includes determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations are, optionally, applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). In some embodiments, contact/motion module  130  and display controller  156  detect contact on a touchpad. 
     In some embodiments, contact/motion module  130  uses a set of one or more intensity thresholds to determine whether an operation has been performed by a user (e.g., to determine whether a user has “clicked” on an icon). In some embodiments, at least a subset of the intensity thresholds are determined in accordance with software parameters (e.g., the intensity thresholds are not determined by the activation thresholds of particular physical actuators and can be adjusted without changing the physical hardware of device  100 ). For example, a mouse “click” threshold of a trackpad or touch screen display can be set to any of a large range of predefined threshold values without changing the trackpad or touch screen display hardware. Additionally, in some implementations, a user of the device is provided with software settings for adjusting one or more of the set of intensity thresholds (e.g., by adjusting individual intensity thresholds and/or by adjusting a plurality of intensity thresholds at once with a system-level click “intensity” parameter). 
     Contact/motion module  130  optionally detects a gesture input by a user. Different gestures on the touch-sensitive surface have different contact patterns (e.g., different motions, timings, and/or intensities of detected contacts). Thus, a gesture is, optionally, detected by detecting a particular contact pattern. For example, detecting a finger tap gesture includes detecting a finger-down event followed by detecting a finger-up (liftoff) event at the same position (or substantially the same position) as the finger-down event (e.g., at the position of an icon). As another example, detecting a finger swipe gesture on the touch-sensitive surface includes detecting a finger-down event followed by detecting one or more finger-dragging events, and subsequently followed by detecting a finger-up (liftoff) event. 
     Graphics module  132  includes various known software components for rendering and displaying graphics on touch screen  112  or other display, including components for changing the visual impact (e.g., brightness, transparency, saturation, contrast, or other visual property) of graphics that are displayed. As used herein, the term “graphics” includes any object that can be displayed to a user, including, without limitation, text, web pages, icons (such as user-interface objects including soft keys), digital images, videos, animations, and the like. 
     In some embodiments, graphics module  132  stores data representing graphics to be used. Each graphic is, optionally, assigned a corresponding code. Graphics module  132  receives, from applications etc., one or more codes specifying graphics to be displayed along with, if necessary, coordinate data and other graphic property data, and then generates screen image data to output to display controller  156 . 
     Haptic feedback module  133  includes various software components for generating instructions used by tactile output generator(s)  167  to produce tactile outputs at one or more locations on device  100  in response to user interactions with device  100 . 
     Text input module  134 , which is, optionally, a component of graphics module  132 , provides soft keyboards for entering text in various applications (e.g., contacts  137 , e-mail  140 , IM  141 , browser  147 , and any other application that needs text input). 
     GPS module  135  determines the location of the device and provides this information for use in various applications (e.g., to telephone  138  for use in location-based dialing; to camera  143  as picture/video metadata; and to applications that provide location-based services such as weather widgets, local yellow page widgets, and map/navigation widgets). 
     Applications  136  optionally include the following modules (or sets of instructions), or a subset or superset thereof:
         Contacts module  137  (sometimes called an address book or contact list);   Telephone module  138 ;   Video conference module  139 ;   E-mail client module  140 ;   Instant messaging (IM) module  141 ;   Workout support module  142 ;   Camera module  143  for still and/or video images;   Image management module  144 ;   Video player module;   Music player module;   Browser module  147 ;   Calendar module  148 ;   Widget modules  149 , which optionally include one or more of: weather widget  149 - 1 , stocks widget  149 - 2 , calculator widget  149 - 3 , alarm clock widget  149 - 4 , dictionary widget  149 - 5 , and other widgets obtained by the user, as well as user-created widgets  149 - 6 ;   Widget creator module  150  for making user-created widgets  149 - 6 ;   Search module  151 ;   Video and music player module  152 , which merges video player module and music player module;   Notes module  153 ;   Map module  154 ; and/or   Online video module  155 .       

     Examples of other applications  136  that are, optionally, stored in memory  102  include other word processing applications, other image editing applications, drawing applications, presentation applications, JAVA-enabled applications, encryption, digital rights management, voice recognition, and voice replication. 
     In conjunction with touch screen  112 , display controller  156 , contact/motion module  130 , graphics module  132 , and text input module  134 , contacts module  137  are, optionally, used to manage an address book or contact list (e.g., stored in application internal state  192  of contacts module  137  in memory  102  or memory  370 ), including: adding name(s) to the address book; deleting name(s) from the address book; associating telephone number(s), e-mail address(es), physical address(es) or other information with a name; associating an image with a name; categorizing and sorting names; providing telephone numbers or e-mail addresses to initiate and/or facilitate communications by telephone  138 , video conference module  139 , e-mail  140 , or IM  141 ; and so forth.

Additional description of the online video application can be found in U.S. Provisional Patent Application No. 60/936,562, “Portable Multifunction Device, Method, and Graphical User Interface for Playing Online Videos,” filed Jun. 20, 2007, and U.S. patent application Ser. No. 11/968,067, “Portable Multifunction Device, Method, and Graphical User Interface for Playing Online Videos,” filed Dec. 31, 2007, the contents of which are hereby incorporated by reference in their entirety. 
     Each of the above-identified modules and applications corresponds to a set of executable instructions for performing one or more functions described above and the methods described in this application (e.g., the computer-implemented methods and other information processing methods described herein). These modules (e.g., sets of instructions) need not be implemented as separate software programs, procedures, or modules, and thus various subsets of these modules are, optionally, combined or otherwise rearranged in various embodiments. For example, video player module is, optionally, combined with music player module into a single module (e.g., video and music player module  152 ,  FIG. 1A ). In some embodiments, memory  102  optionally stores a subset of the modules and data structures identified above. Furthermore, memory  102  optionally stores additional modules and data structures not described above. 
     In some embodiments, device  100  is a device where operation of a predefined set of functions on the device is performed exclusively through a touch screen and/or a touchpad. By using a touch screen and/or a touchpad as the primary input control device for operation of device  100 , the number of physical input control devices (such as push buttons, dials, and the like) on device  100  is, optionally, reduced. 
     The predefined set of functions that are performed exclusively through a touch screen and/or a touchpad optionally include navigation between user interfaces. In some embodiments, the touchpad, when touched by the user, navigates device  100  to a main, home, or root menu from any user interface that is displayed on device  100 . In such embodiments, a “menu button” is implemented using a touchpad. In some other embodiments, the menu button is a physical push button or other physical input control device instead of a touchpad. 
       FIG. 1B  is a block diagram illustrating exemplary components for event handling in accordance with some embodiments. In some embodiments, memory  102  ( FIG. 1A ) or  370  ( FIG. 3 ) includes event sorter  170  (e.g., in operating system  126 ) and a respective application  136 - 1  (e.g., any of the aforementioned applications  137 - 151 ,  155 ,  380 - 390 ). 
     Event sorter  170  receives event information and determines the application  136 - 1  and application view  191  of application  136 - 1  to which to deliver the event information. Event sorter  170  includes event monitor  171  and event dispatcher module  174 . In some embodiments, application  136 - 1  includes application internal state  192 , which indicates the current application view(s) displayed on touch-sensitive display  112  when the application is active or executing. In some embodiments, device/global internal state  157  is used by event sorter  170  to determine which application(s) is (are) currently active, and application internal state  192  is used by event sorter  170  to determine application views  191  to which to deliver event information. 
     In some embodiments, application internal state  192  includes additional information, such as one or more of: resume information to be used when application  136 - 1  resumes execution, user interface state information that indicates information being displayed or that is ready for display by application  136 - 1 , a state queue for enabling the user to go back to a prior state or view of application  136 - 1 , and a redo/undo queue of previous actions taken by the user. 
     Event monitor  171  receives event information from peripherals interface  118 . Event information includes information about a sub-event (e.g., a user touch on touch-sensitive display  112 , as part of a multi-touch gesture). Peripherals interface  118  transmits information it receives from I/O subsystem  106  or a sensor, such as proximity sensor  166 , accelerometer(s)  168 , and/or microphone  113  (through audio circuitry  110 ). Information that peripherals interface  118  receives from I/O subsystem  106  includes information from touch-sensitive display  112  or a touch-sensitive surface. 
     In some embodiments, event monitor  171  sends requests to the peripherals interface  118  at predetermined intervals. In response, peripherals interface  118  transmits event information. In other embodiments, peripherals interface  118  transmits event information only when there is a significant event (e.g., receiving an input above a predetermined noise threshold and/or for more than a predetermined duration). 
     In some embodiments, event sorter  170  also includes a hit view determination module  172  and/or an active event recognizer determination module  173 . 
     Hit view determination module  172  provides software procedures for determining where a sub-event has taken place within one or more views when touch-sensitive display  112  displays more than one view. Views are made up of controls and other elements that a user can see on the display. 
     Another aspect of the user interface associated with an application is a set of views, sometimes herein called application views or user interface windows, in which information is displayed and touch-based gestures occur. The application views (of a respective application) in which a touch is detected optionally correspond to programmatic levels within a programmatic or view hierarchy of the application. For example, the lowest level view in which a touch is detected is, optionally, called the hit view, and the set of events that are recognized as proper inputs are, optionally, determined based, at least in part, on the hit view of the initial touch that begins a touch-based gesture. 
     Hit view determination module  172  receives information related to sub-events of a touch-based gesture. When an application has multiple views organized in a hierarchy, hit view determination module  172  identifies a hit view as the lowest view in the hierarchy which should handle the sub-event. In most circumstances, the hit view is the lowest level view in which an initiating sub-event occurs (e.g., the first sub-event in the sequence of sub-events that form an event or potential event). Once the hit view is identified by the hit view determination module  172 , the hit view typically receives all sub-events related to the same touch or input source for which it was identified as the hit view. 
     Active event recognizer determination module  173  determines which view or views within a view hierarchy should receive a particular sequence of sub-events. In some embodiments, active event recognizer determination module  173  determines that only the hit view should receive a particular sequence of sub-events. In other embodiments, active event recognizer determination module  173  determines that all views that include the physical location of a sub-event are actively involved views, and therefore determines that all actively involved views should receive a particular sequence of sub-events. In other embodiments, even if touch sub-events were entirely confined to the area associated with one particular view, views higher in the hierarchy would still remain as actively involved views. 
     Event dispatcher module  174  dispatches the event information to an event recognizer (e.g., event recognizer  180 ). In embodiments including active event recognizer determination module  173 , event dispatcher module  174  delivers the event information to an event recognizer determined by active event recognizer determination module  173 . In some embodiments, event dispatcher module  174  stores in an event queue the event information, which is retrieved by a respective event receiver  182 . 
     In some embodiments, operating system  126  includes event sorter  170 . Alternatively, application  136 - 1  includes event sorter  170 . In yet other embodiments, event sorter  170  is a stand-alone module, or a part of another module stored in memory  102 , such as contact/motion module  130 . 
     In some embodiments, application  136 - 1  includes a plurality of event handlers  190  and one or more application views  191 , each of which includes instructions for handling touch events that occur within a respective view of the application&#39;s user interface. Each application view  191  of the application  136 - 1  includes one or more event recognizers  180 . Typically, a respective application view  191  includes a plurality of event recognizers  180 . In other embodiments, one or more of event recognizers  180  are part of a separate module, such as a user interface kit (not shown) or a higher level object from which application  136 - 1  inherits methods and other properties. In some embodiments, a respective event handler  190  includes one or more of: data updater  176 , object updater  177 , GUI updater  178 , and/or event data  179  received from event sorter  170 . Event handler  190  optionally utilizes or calls data updater  176 , object updater  177 , or GUI updater  178  to update the application internal state  192 . Alternatively, one or more of the application views  191  include one or more respective event handlers  190 . Also, in some embodiments, one or more of data updater  176 , object updater  177 , and GUI updater  178  are included in a respective application view  191 . 
     A respective event recognizer  180  receives event information (e.g., event data  179 ) from event sorter  170  and identifies an event from the event information. Event recognizer  180  includes event receiver  182  and event comparator  184 . In some embodiments, event recognizer  180  also includes at least a subset of: metadata  183 , and event delivery instructions  188  (which optionally include sub-event delivery instructions). 
     Event receiver  182  receives event information from event sorter  170 . The event information includes information about a sub-event, for example, a touch or a touch movement. Depending on the sub-event, the event information also includes additional information, such as location of the sub-event. When the sub-event concerns motion of a touch, the event information optionally also includes speed and direction of the sub-event. In some embodiments, events include rotation of the device from one orientation to another (e.g., from a portrait orientation to a landscape orientation, or vice versa), and the event information includes corresponding information about the current orientation (also called device attitude) of the device. 
     Event comparator  184  compares the event information to predefined event or sub-event definitions and, based on the comparison, determines an event or sub-event, or determines or updates the state of an event or sub-event. In some embodiments, event comparator  184  includes event definitions  186 . Event definitions  186  contain definitions of events (e.g., predefined sequences of sub-events), for example, event  1  ( 187 - 1 ), event  2  ( 187 - 2 ), and others. In some embodiments, sub-events in an event ( 187 ) include, for example, touch begin, touch end, touch movement, touch cancellation, and multiple touching. In one example, the definition for event  1  ( 187 - 1 ) is a double tap on a displayed object. The double tap, for example, comprises a first touch (touch begin) on the displayed object for a predetermined phase, a first liftoff (touch end) for a predetermined phase, a second touch (touch begin) on the displayed object for a predetermined phase, and a second liftoff (touch end) for a predetermined phase. In another example, the definition for event  2  ( 187 - 2 ) is a dragging on a displayed object. The dragging, for example, comprises a touch (or contact) on the displayed object for a predetermined phase, a movement of the touch across touch-sensitive display  112 , and liftoff of the touch (touch end). In some embodiments, the event also includes information for one or more associated event handlers  190 . 
     In some embodiments, event definition  187  includes a definition of an event for a respective user-interface object. In some embodiments, event comparator  184  performs a hit test to determine which user-interface object is associated with a sub-event. For example, in an application view in which three user-interface objects are displayed on touch-sensitive display  112 , when a touch is detected on touch-sensitive display  112 , event comparator  184  performs a hit test to determine which of the three user-interface objects is associated with the touch (sub-event). If each displayed object is associated with a respective event handler  190 , the event comparator uses the result of the hit test to determine which event handler  190  should be activated. For example, event comparator  184  selects an event handler associated with the sub-event and the object triggering the hit test. 
     In some embodiments, the definition for a respective event ( 187 ) also includes delayed actions that delay delivery of the event information until after it has been determined whether the sequence of sub-events does or does not correspond to the event recognizer&#39;s event type. 
     When a respective event recognizer  180  determines that the series of sub-events do not match any of the events in event definitions  186 , the respective event recognizer  180  enters an event impossible, event failed, or event ended state, after which it disregards subsequent sub-events of the touch-based gesture. In this situation, other event recognizers, if any, that remain active for the hit view continue to track and process sub-events of an ongoing touch-based gesture. 
     In some embodiments, a respective event recognizer  180  includes metadata  183  with configurable properties, flags, and/or lists that indicate how the event delivery system should perform sub-event delivery to actively involved event recognizers. In some embodiments, metadata  183  includes configurable properties, flags, and/or lists that indicate how event recognizers interact, or are enabled to interact, with one another. In some embodiments, metadata  183  includes configurable properties, flags, and/or lists that indicate whether sub-events are delivered to varying levels in the view or programmatic hierarchy. 
     In some embodiments, a respective event recognizer  180  activates event handler  190  associated with an event when one or more particular sub-events of an event are recognized. In some embodiments, a respective event recognizer  180  delivers event information associated with the event to event handler  190 . Activating an event handler  190  is distinct from sending (and deferred sending) sub-events to a respective hit view. In some embodiments, event recognizer  180  throws a flag associated with the recognized event, and event handler  190  associated with the flag catches the flag and performs a predefined process. 
     In some embodiments, event delivery instructions  188  include sub-event delivery instructions that deliver event information about a sub-event without activating an event handler. Instead, the sub-event delivery instructions deliver event information to event handlers associated with the series of sub-events or to actively involved views. Event handlers associated with the series of sub-events or with actively involved views receive the event information and perform a predetermined process. 
     In some embodiments, data updater  176  creates and updates data used in application  136 - 1 . For example, data updater  176  updates the telephone number used in contacts module  137 , or stores a video file used in video player module. In some embodiments, object updater  177  creates and updates objects used in application  136 - 1 . For example, object updater  177  creates a new user-interface object or updates the position of a user-interface object. GUI updater  178  updates the GUI. For example, GUI updater  178  prepares display information and sends it to graphics module  132  for display on a touch-sensitive display. 
     In some embodiments, event handler(s)  190  includes or has access to data updater  176 , object updater  177 , and GUI updater  178 . In some embodiments, data updater  176 , object updater  177 , and GUI updater  178  are included in a single module of a respective application  136 - 1  or application view  191 . In other embodiments, they are included in two or more software modules. 
     It shall be understood that the foregoing discussion regarding event handling of user touches on touch-sensitive displays also applies to other forms of user inputs to operate multifunction devices  100  with input devices, not all of which are initiated on touch screens. For example, mouse movement and mouse button presses, optionally coordinated with single or multiple keyboard presses or holds; contact movements such as taps, drags, scrolls, etc. on touchpads; pen stylus inputs; movement of the device; oral instructions; detected eye movements; biometric inputs; and/or any combination thereof are optionally utilized as inputs corresponding to sub-events which define an event to be recognized. 
       FIG. 2  illustrates a portable multifunction device  100  having a touch screen  112  in accordance with some embodiments. The touch screen optionally displays one or more graphics within user interface (UI)  200 . In this embodiment, as well as others described below, a user is enabled to select one or more of the graphics by making a gesture on the graphics, for example, with one or more fingers  202  (not drawn to scale in the figure) or one or more styluses  203  (not drawn to scale in the figure). In some embodiments, selection of one or more graphics occurs when the user breaks contact with the one or more graphics. In some embodiments, the gesture optionally includes one or more taps, one or more swipes (from left to right, right to left, upward and/or downward), and/or a rolling of a finger (from right to left, left to right, upward and/or downward) that has made contact with device  100 . In some implementations or circumstances, inadvertent contact with a graphic does not select the graphic. For example, a swipe gesture that sweeps over an application icon optionally does not select the corresponding application when the gesture corresponding to selection is a tap. 
     Device  100  optionally also include one or more physical buttons, such as “home” or menu button  204 . As described previously, menu button  204  is, optionally, used to navigate to any application  136  in a set of applications that are, optionally, executed on device  100 . Alternatively, in some embodiments, the menu button is implemented as a soft key in a GUI displayed on touch screen  112 . 
     In some embodiments, device  100  includes touch screen  112 , menu button  204 , push button  206  for powering the device on/off and locking the device, volume adjustment button(s)  208 , subscriber identity module (SIM) card slot  210 , headset jack  212 , and docking/charging external port  124 . Push button  206  is, optionally, used to turn the power on/off on the device by depressing the button and holding the button in the depressed state for a predefined time interval; to lock the device by depressing the button and releasing the button before the predefined time interval has elapsed; and/or to unlock the device or initiate an unlock process. In an alternative embodiment, device  100  also accepts verbal input for activation or deactivation of some functions through microphone  113 . Device  100  also, optionally, includes one or more contact intensity sensors  165  for detecting intensity of contacts on touch screen  112  and/or one or more tactile output generators  167  for generating tactile outputs for a user of device  100 . 
       FIG. 3  is a block diagram of an exemplary multifunction device with a display and a touch-sensitive surface in accordance with some embodiments. Device  300  need not be portable. In some embodiments, device  300  is a laptop computer, a desktop computer, a tablet computer, a multimedia player device, a navigation device, an educational device (such as a child&#39;s learning toy), a gaming system, or a control device (e.g., a home or industrial controller). Device  300  typically includes one or more processing units (CPUs)  310 , one or more network or other communications interfaces  360 , memory  370 , and one or more communication buses  320  for interconnecting these components. Communication buses  320  optionally include circuitry (sometimes called a chipset) that interconnects and controls communications between system components. Device  300  includes input/output (I/O) interface  330  comprising display  340 , which is typically a touch screen display. I/O interface  330  also optionally includes a keyboard and/or mouse (or other pointing device)  350  and touchpad  355 , tactile output generator  357  for generating tactile outputs on device  300  (e.g., similar to tactile output generator(s)  167  described above with reference to  FIG. 1A ), sensors  359  (e.g., optical, acceleration, proximity, touch-sensitive, and/or contact intensity sensors similar to contact intensity sensor(s)  165  described above with reference to  FIG. 1A ). Memory  370  includes high-speed random access memory, such as DRAM, SRAM, DDR RAM, or other random access solid state memory devices; and optionally includes non-volatile memory, such as one or more magnetic disk storage devices, optical disk storage devices, flash memory devices, or other non-volatile solid state storage devices. Memory  370  optionally includes one or more storage devices remotely located from CPU(s)  310 . In some embodiments, memory  370  stores programs, modules, and data structures analogous to the programs, modules, and data structures stored in memory  102  of portable multifunction device  100  ( FIG. 1A ), or a subset thereof. Furthermore, memory  370  optionally stores additional programs, modules, and data structures not present in memory  102  of portable multifunction device  100 . For example, memory  370  of device  300  optionally stores drawing module  380 , presentation module  382 , word processing module  384 , website creation module  386 , disk authoring module  388 , and/or spreadsheet module  390 , while memory  102  of portable multifunction device  100  ( FIG. 1A ) optionally does not store these modules. 
     Each of the above-identified elements in  FIG. 3  is, optionally, stored in one or more of the previously mentioned memory devices. Each of the above-identified modules corresponds to a set of instructions for performing a function described above. The above-identified modules or programs (e.g., sets of instructions) need not be implemented as separate software programs, procedures, or modules, and thus various subsets of these modules are, optionally, combined or otherwise rearranged in various embodiments. In some embodiments, memory  370  optionally stores a subset of the modules and data structures identified above. Furthermore, memory  370  optionally stores additional modules and data structures not described above. 
     Attention is now directed towards embodiments of user interfaces that are, optionally, implemented on, for example, portable multifunction device  100 . 
       FIG. 4A  illustrates an exemplary user interface for a menu of applications on portable multifunction device  100  in accordance with some embodiments. Similar user interfaces are, optionally, implemented on device  300 . In some embodiments, user interface  400  includes the following elements, or a subset or superset thereof:
         Signal strength indicator(s)  402  for wireless communication(s), such as cellular and Wi-Fi signals;   Time  404 ;   Bluetooth indicator  405 ;   Battery status indicator  406 ;   Tray  408  with icons for frequently used applications, such as:
           Icon  416  for telephone module  138 , labeled “Phone,” which optionally includes an indicator  414  of the number of missed calls or voicemail messages;   Icon  418  for e-mail client module  140 , labeled “Mail,” which optionally includes an indicator  410  of the number of unread e-mails;   Icon  420  for browser module  147 , labeled “Browser;” and   Icon  422  for video and music player module  152 , also referred to as iPod (trademark of Apple Inc.) module  152 , labeled “iPod;” and   
           Icons for other applications, such as:
           Icon  424  for IM module  141 , labeled “Messages;”   Icon  426  for calendar module  148 , labeled “Calendar;”   Icon  428  for image management module  144 , labeled “Photos;”   Icon  430  for camera module  143 , labeled “Camera;”   Icon  432  for online video module  155 , labeled “Online Video;”   Icon  434  for stocks widget  149 - 2 , labeled “Stocks;”   Icon  436  for map module  154 , labeled “Maps;”   Icon  438  for weather widget  149 - 1 , labeled “Weather;”   Icon  440  for alarm clock widget  149 - 4 , labeled “Clock;”   Icon  442  for workout support module  142 , labeled “Workout Support;”   Icon  444  for notes module  153 , labeled “Notes;” and   Icon  446  for a settings application or module, labeled “Settings,” which provides access to settings for device  100  and its various applications  136 .   
               

     It should be noted that the icon labels illustrated in  FIG. 4A  are merely exemplary. For example, icon  422  for video and music player module  152  is labeled “Music” or “Music Player.” Other labels are, optionally, used for various application icons. In some embodiments, a label for a respective application icon includes a name of an application corresponding to the respective application icon. In some embodiments, a label for a particular application icon is distinct from a name of an application corresponding to the particular application icon. 
       FIG. 4B  illustrates an exemplary user interface on a device (e.g., device  300 ,  FIG. 3 ) with a touch-sensitive surface  451  (e.g., a tablet or touchpad  355 ,  FIG. 3 ) that is separate from the display  450  (e.g., touch screen display  112 ). Device  300  also, optionally, includes one or more contact intensity sensors (e.g., one or more of sensors  359 ) for detecting intensity of contacts on touch-sensitive surface  451  and/or one or more tactile output generators  357  for generating tactile outputs for a user of device  300 . 
     Although some of the examples that follow will be given with reference to inputs on touch screen display  112  (where the touch-sensitive surface and the display are combined), in some embodiments, the device detects inputs on a touch-sensitive surface that is separate from the display, as shown in  FIG. 4B . In some embodiments, the touch-sensitive surface (e.g.,  451  in  FIG. 4B ) has a primary axis (e.g.,  452  in  FIG. 4B ) that corresponds to a primary axis (e.g.,  453  in  FIG. 4B ) on the display (e.g.,  450 ). In accordance with these embodiments, the device detects contacts (e.g.,  460  and  462  in  FIG. 4B ) with the touch-sensitive surface  451  at locations that correspond to respective locations on the display (e.g., in  FIG. 4B, 460  corresponds to  468  and  462  corresponds to  470 ). In this way, user inputs (e.g., contacts  460  and  462 , and movements thereof) detected by the device on the touch-sensitive surface (e.g.,  451  in  FIG. 4B ) are used by the device to manipulate the user interface on the display (e.g.,  450  in  FIG. 4B ) of the multifunction device when the touch-sensitive surface is separate from the display. It should be understood that similar methods are, optionally, used for other user interfaces described herein. 
     Additionally, while the following examples are given primarily with reference to finger inputs (e.g., finger contacts, finger tap gestures, finger swipe gestures), it should be understood that, in some embodiments, one or more of the finger inputs are replaced with input from another input device (e.g., a mouse-based input or stylus input). For example, a swipe gesture is, optionally, replaced with a mouse click (e.g., instead of a contact) followed by movement of the cursor along the path of the swipe (e.g., instead of movement of the contact). As another example, a tap gesture is, optionally, replaced with a mouse click while the cursor is located over the location of the tap gesture (e.g., instead of detection of the contact followed by ceasing to detect the contact). Similarly, when multiple user inputs are simultaneously detected, it should be understood that multiple computer mice are, optionally, used simultaneously, or a mouse and finger contacts are, optionally, used simultaneously. 
       FIG. 5A  illustrates exemplary personal electronic device  500 . Device  500  includes body  502 . In some embodiments, device  500  can include some or all of the features described with respect to devices  100  and  300  (e.g.,  FIGS. 1A-4B ). In some embodiments, device  500  has touch-sensitive display screen  504 , hereafter touch screen  504 . Alternatively, or in addition to touch screen  504 , device  500  has a display and a touch-sensitive surface. As with devices  100  and  300 , in some embodiments, touch screen  504  (or the touch-sensitive surface) optionally includes one or more intensity sensors for detecting intensity of contacts (e.g., touches) being applied. The one or more intensity sensors of touch screen  504  (or the touch-sensitive surface) can provide output data that represents the intensity of touches. The user interface of device  500  can respond to touches based on their intensity, meaning that touches of different intensities can invoke different user interface operations on device  500 . 
     Exemplary techniques for detecting and processing touch intensity are found, for example, in related applications: International Patent Application Serial No. PCT/US2013/040061, titled “Device, Method, and Graphical User Interface for Displaying User Interface Objects Corresponding to an Application,” filed May 8, 2013, published as WIPO Publication No. WO/2013/169849, and International Patent Application Serial No. PCT/US2013/069483, titled “Device, Method, and Graphical User Interface for Transitioning Between Touch Input to Display Output Relationships,” filed Nov. 11, 2013, published as WIPO Publication No. WO/2014/105276, each of which is hereby incorporated by reference in their entirety. 
     In some embodiments, device  500  has one or more input mechanisms  506  and  508 . Input mechanisms  506  and  508 , if included, can be physical. Examples of physical input mechanisms include push buttons and rotatable mechanisms. In some embodiments, device  500  has one or more attachment mechanisms. Such attachment mechanisms, if included, can permit attachment of device  500  with, for example, hats, eyewear, earrings, necklaces, shirts, jackets, bracelets, watch straps, chains, trousers, belts, shoes, purses, backpacks, and so forth. These attachment mechanisms permit device  500  to be worn by a user. 
       FIG. 5B  depicts exemplary personal electronic device  500 . In some embodiments, device  500  can include some or all of the components described with respect to  FIGS. 1A, 1B , and  3 . Device  500  has bus  512  that operatively couples I/O section  514  with one or more computer processors  516  and memory  518 . I/O section  514  can be connected to display  504 , which can have touch-sensitive component  522  and, optionally, intensity sensor  524  (e.g., contact intensity sensor). In addition, I/O section  514  can be connected with communication unit  530  for receiving application and operating system data, using Wi-Fi, Bluetooth, near field communication (NFC), cellular, and/or other wireless communication techniques. Device  500  can include input mechanisms  506  and/or  508 . Input mechanism  506  is, optionally, a rotatable input device or a depressible and rotatable input device (e.g., a rotating crown), for example. Input mechanism  508  is, optionally, a button, in some examples. 
     Input mechanism  508  is, optionally, a microphone, in some examples. Personal electronic device  500  optionally includes various sensors, such as GPS sensor  532 , accelerometer  534 , directional sensor  540  (e.g., compass), gyroscope  536 , motion sensor  538 , and/or a combination thereof, all of which can be operatively connected to I/O section  514 . 
     Memory  518  of personal electronic device  500  can include one or more non-transitory computer-readable storage mediums, for storing computer-executable instructions, which, when executed by one or more computer processors  516 , for example, can cause the computer processors to perform the techniques described below, including processes  700  ( FIGS. 7A-7C ),  900  ( FIGS. 9A-9B ),  1100  ( FIG. 11 ), and  1300  ( FIGS. 13A-13B ). A computer-readable storage medium can be any medium that can tangibly contain or store computer-executable instructions for use by or in connection with the instruction execution system, apparatus, or device. In some examples, the storage medium is a transitory computer-readable storage medium. In some examples, the storage medium is a non-transitory computer-readable storage medium. The non-transitory computer-readable storage medium can include, but is not limited to, magnetic, optical, and/or semiconductor storages. Examples of such storage include magnetic disks, optical discs based on CD, DVD, or Blu-ray technologies, as well as persistent solid-state memory such as flash, solid-state drives, and the like. Personal electronic device  500  is not limited to the components and configuration of  FIG. 5B , but can include other or additional components in multiple configurations. 
     As used here, the term “affordance” refers to a user-interactive graphical user interface object that is, optionally, displayed on the display screen of devices  100 ,  300 , and/or  500  ( FIGS. 1A, 3, and 5A-5B ). For example, an image (e.g., icon), a button, and text (e.g., hyperlink) each optionally constitute an affordance. 
     As used herein, the term “focus selector” refers to an input element that indicates a current part of a user interface with which a user is interacting. In some implementations that include a cursor or other location marker, the cursor acts as a “focus selector” so that when an input (e.g., a press input) is detected on a touch-sensitive surface (e.g., touchpad  355  in  FIG. 3  or touch-sensitive surface  451  in  FIG. 4B ) while the cursor is over a particular user interface element (e.g., a button, window, slider, or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations that include a touch screen display (e.g., touch-sensitive display system  112  in  FIG. 1A  or touch screen  112  in  FIG. 4A ) that enables direct interaction with user interface elements on the touch screen display, a detected contact on the touch screen acts as a “focus selector” so that when an input (e.g., a press input by the contact) is detected on the touch screen display at a location of a particular user interface element (e.g., a button, window, slider, or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations, focus is moved from one region of a user interface to another region of the user interface without corresponding movement of a cursor or movement of a contact on a touch screen display (e.g., by using a tab key or arrow keys to move focus from one button to another button); in these implementations, the focus selector moves in accordance with movement of focus between different regions of the user interface. Without regard to the specific form taken by the focus selector, the focus selector is generally the user interface element (or contact on a touch screen display) that is controlled by the user so as to communicate the user&#39;s intended interaction with the user interface (e.g., by indicating, to the device, the element of the user interface with which the user is intending to interact). For example, the location of a focus selector (e.g., a cursor, a contact, or a selection box) over a respective button while a press input is detected on the touch-sensitive surface (e.g., a touchpad or touch screen) will indicate that the user is intending to activate the respective button (as opposed to other user interface elements shown on a display of the device). 
     As used in the specification and claims, the term “characteristic intensity” of a contact refers to a characteristic of the contact based on one or more intensities of the contact. In some embodiments, the characteristic intensity is based on multiple intensity samples. The characteristic intensity is, optionally, based on a predefined number of intensity samples, or a set of intensity samples collected during a predetermined time period (e.g., 0.05, 0.1, 0.2, 0.5, 1, 2, 5, 10 seconds) relative to a predefined event (e.g., after detecting the contact, prior to detecting liftoff of the contact, before or after detecting a start of movement of the contact, prior to detecting an end of the contact, before or after detecting an increase in intensity of the contact, and/or before or after detecting a decrease in intensity of the contact). A characteristic intensity of a contact is, optionally, based on one or more of: a maximum value of the intensities of the contact, a mean value of the intensities of the contact, an average value of the intensities of the contact, a top 10 percentile value of the intensities of the contact, a value at the half maximum of the intensities of the contact, a value at the 90 percent maximum of the intensities of the contact, or the like. In some embodiments, the duration of the contact is used in determining the characteristic intensity (e.g., when the characteristic intensity is an average of the intensity of the contact over time). In some embodiments, the characteristic intensity is compared to a set of one or more intensity thresholds to determine whether an operation has been performed by a user. For example, the set of one or more intensity thresholds optionally includes a first intensity threshold and a second intensity threshold. In this example, a contact with a characteristic intensity that does not exceed the first threshold results in a first operation, a contact with a characteristic intensity that exceeds the first intensity threshold and does not exceed the second intensity threshold results in a second operation, and a contact with a characteristic intensity that exceeds the second threshold results in a third operation. In some embodiments, a comparison between the characteristic intensity and one or more thresholds is used to determine whether or not to perform one or more operations (e.g., whether to perform a respective operation or forgo performing the respective operation), rather than being used to determine whether to perform a first operation or a second operation. 
       FIG. 5C  illustrates detecting a plurality of contacts  552 A- 552 E on touch-sensitive display screen  504  with a plurality of intensity sensors  524 A- 524 D.  FIG. 5C  additionally includes intensity diagrams that show the current intensity measurements of the intensity sensors  524 A- 524 D relative to units of intensity. In this example, the intensity measurements of intensity sensors  524 A and  524 D are each 9 units of intensity, and the intensity measurements of intensity sensors  524 B and  524 C are each 7 units of intensity. In some implementations, an aggregate intensity is the sum of the intensity measurements of the plurality of intensity sensors  524 A- 524 D, which in this example is 32 intensity units. In some embodiments, each contact is assigned a respective intensity that is a portion of the aggregate intensity.  FIG. 5D  illustrates assigning the aggregate intensity to contacts  552 A- 552 E based on their distance from the center of force  554 . In this example, each of contacts  552 A,  552 B, and  552 E are assigned an intensity of contact of 8 intensity units of the aggregate intensity, and each of contacts  552 C and  552 D are assigned an intensity of contact of 4 intensity units of the aggregate intensity. More generally, in some implementations, each contact j is assigned a respective intensity Ij that is a portion of the aggregate intensity, A, in accordance with a predefined mathematical function, Ij=A·(Dj/ΣDi), where Dj is the distance of the respective contact j to the center of force, and ΣDi is the sum of the distances of all the respective contacts (e.g., i=1 to last) to the center of force. The operations described with reference to  FIGS. 5C-5D  can be performed using an electronic device similar or identical to device  100 ,  300 , or  500 . In some embodiments, a characteristic intensity of a contact is based on one or more intensities of the contact. In some embodiments, the intensity sensors are used to determine a single characteristic intensity (e.g., a single characteristic intensity of a single contact). It should be noted that the intensity diagrams are not part of a displayed user interface, but are included in  FIGS. 5C-5D  to aid the reader. 
     In some embodiments, a portion of a gesture is identified for purposes of determining a characteristic intensity. For example, a touch-sensitive surface optionally receives a continuous swipe contact transitioning from a start location and reaching an end location, at which point the intensity of the contact increases. In this example, the characteristic intensity of the contact at the end location is, optionally, based on only a portion of the continuous swipe contact, and not the entire swipe contact (e.g., only the portion of the swipe contact at the end location). In some embodiments, a smoothing algorithm is, optionally, applied to the intensities of the swipe contact prior to determining the characteristic intensity of the contact. For example, the smoothing algorithm optionally includes one or more of: an unweighted sliding-average smoothing algorithm, a triangular smoothing algorithm, a median filter smoothing algorithm, and/or an exponential smoothing algorithm. In some circumstances, these smoothing algorithms eliminate narrow spikes or dips in the intensities of the swipe contact for purposes of determining a characteristic intensity. 
     The intensity of a contact on the touch-sensitive surface is, optionally, characterized relative to one or more intensity thresholds, such as a contact-detection intensity threshold, a light press intensity threshold, a deep press intensity threshold, and/or one or more other intensity thresholds. In some embodiments, the light press intensity threshold corresponds to an intensity at which the device will perform operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, the deep press intensity threshold corresponds to an intensity at which the device will perform operations that are different from operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, when a contact is detected with a characteristic intensity below the light press intensity threshold (e.g., and above a nominal contact-detection intensity threshold below which the contact is no longer detected), the device will move a focus selector in accordance with movement of the contact on the touch-sensitive surface without performing an operation associated with the light press intensity threshold or the deep press intensity threshold. Generally, unless otherwise stated, these intensity thresholds are consistent between different sets of user interface figures. 
     An increase of characteristic intensity of the contact from an intensity below the light press intensity threshold to an intensity between the light press intensity threshold and the deep press intensity threshold is sometimes referred to as a “light press” input. An increase of characteristic intensity of the contact from an intensity below the deep press intensity threshold to an intensity above the deep press intensity threshold is sometimes referred to as a “deep press” input. An increase of characteristic intensity of the contact from an intensity below the contact-detection intensity threshold to an intensity between the contact-detection intensity threshold and the light press intensity threshold is sometimes referred to as detecting the contact on the touch-surface. A decrease of characteristic intensity of the contact from an intensity above the contact-detection intensity threshold to an intensity below the contact-detection intensity threshold is sometimes referred to as detecting liftoff of the contact from the touch-surface. In some embodiments, the contact-detection intensity threshold is zero. In some embodiments, the contact-detection intensity threshold is greater than zero. 
     In some embodiments described herein, one or more operations are performed in response to detecting a gesture that includes a respective press input or in response to detecting the respective press input performed with a respective contact (or a plurality of contacts), where the respective press input is detected based at least in part on detecting an increase in intensity of the contact (or plurality of contacts) above a press-input intensity threshold. In some embodiments, the respective operation is performed in response to detecting the increase in intensity of the respective contact above the press-input intensity threshold (e.g., a “down stroke” of the respective press input). In some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the press-input threshold (e.g., an “up stroke” of the respective press input). 
       FIGS. 5E-5H  illustrate detection of a gesture that includes a press input that corresponds to an increase in intensity of a contact  562  from an intensity below a light press intensity threshold (e.g., “IT L ”) in  FIG. 5E , to an intensity above a deep press intensity threshold (e.g., “IT D ”) in  FIG. 5H . The gesture performed with contact  562  is detected on touch-sensitive surface  560  while cursor  576  is displayed over application icon  572 B corresponding to App  2 , on a displayed user interface  570  that includes application icons  572 A- 572 D displayed in predefined region  574 . In some embodiments, the gesture is detected on touch-sensitive display  504 . The intensity sensors detect the intensity of contacts on touch-sensitive surface  560 . The device determines that the intensity of contact  562  peaked above the deep press intensity threshold (e.g., “IT D ”). Contact  562  is maintained on touch-sensitive surface  560 . In response to the detection of the gesture, and in accordance with contact  562  having an intensity that goes above the deep press intensity threshold (e.g., “IT D ”) during the gesture, reduced-scale representations  578 A- 578 C (e.g., thumbnails) of recently opened documents for App  2  are displayed, as shown in  FIGS. 5F-5H . In some embodiments, the intensity, which is compared to the one or more intensity thresholds, is the characteristic intensity of a contact. It should be noted that the intensity diagram for contact  562  is not part of a displayed user interface, but is included in  FIGS. 5E-5H  to aid the reader. 
     In some embodiments, the display of representations  578 A- 578 C includes an animation. For example, representation  578 A is initially displayed in proximity of application icon  572 B, as shown in  FIG. 5F . As the animation proceeds, representation  578 A moves upward and representation  578 B is displayed in proximity of application icon  572 B, as shown in  FIG. 5G . Then, representations  578 A moves upward,  578 B moves upward toward representation  578 A, and representation  578 C is displayed in proximity of application icon  572 B, as shown in  FIG. 5H . Representations  578 A- 578 C form an array above icon  572 B. In some embodiments, the animation progresses in accordance with an intensity of contact  562 , as shown in  FIGS. 5F-5G , where the representations  578 A- 578 C appear and move upwards as the intensity of contact  562  increases toward the deep press intensity threshold (e.g., “IT′D”). In some embodiments, the intensity, on which the progress of the animation is based, is the characteristic intensity of the contact. The operations described with reference to  FIGS. 5E-5H  can be performed using an electronic device similar or identical to device  100 ,  300 , or  500 . 
     In some embodiments, the device employs intensity hysteresis to avoid accidental inputs sometimes termed “jitter,” where the device defines or selects a hysteresis intensity threshold with a predefined relationship to the press-input intensity threshold (e.g., the hysteresis intensity threshold is X intensity units lower than the press-input intensity threshold or the hysteresis intensity threshold is 75%, 90%, or some reasonable proportion of the press-input intensity threshold). Thus, in some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the hysteresis intensity threshold that corresponds to the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the hysteresis intensity threshold (e.g., an “up stroke” of the respective press input). Similarly, in some embodiments, the press input is detected only when the device detects an increase in intensity of the contact from an intensity at or below the hysteresis intensity threshold to an intensity at or above the press-input intensity threshold and, optionally, a subsequent decrease in intensity of the contact to an intensity at or below the hysteresis intensity, and the respective operation is performed in response to detecting the press input (e.g., the increase in intensity of the contact or the decrease in intensity of the contact, depending on the circumstances). 
     For ease of explanation, the descriptions of operations performed in response to a press input associated with a press-input intensity threshold or in response to a gesture including the press input are, optionally, triggered in response to detecting either: an increase in intensity of a contact above the press-input intensity threshold, an increase in intensity of a contact from an intensity below the hysteresis intensity threshold to an intensity above the press-input intensity threshold, a decrease in intensity of the contact below the press-input intensity threshold, and/or a decrease in intensity of the contact below the hysteresis intensity threshold corresponding to the press-input intensity threshold. Additionally, in examples where an operation is described as being performed in response to detecting a decrease in intensity of a contact below the press-input intensity threshold, the operation is, optionally, performed in response to detecting a decrease in intensity of the contact below a hysteresis intensity threshold corresponding to, and lower than, the press-input intensity threshold. 
     As used herein, an “installed application” refers to a software application that has been downloaded onto an electronic device (e.g., devices  100 ,  300 , and/or  500 ) and is ready to be launched (e.g., become opened) on the device. In some embodiments, a downloaded application becomes an installed application by way of an installation program that extracts program portions from a downloaded package and integrates the extracted portions with the operating system of the computer system. 
     As used herein, the terms “open application” or “executing application” refer to a software application with retained state information (e.g., as part of device/global internal state  157  and/or application internal state  192 ). An open or executing application is, optionally, any one of the following types of applications:
         an active application, which is currently displayed on a display screen of the device that the application is being used on;   a background application (or background processes), which is not currently displayed, but one or more processes for the application are being processed by one or more processors; and   a suspended or hibernated application, which is not running, but has state information that is stored in memory (volatile and non-volatile, respectively) and that can be used to resume execution of the application.       

     As used herein, the term “closed application” refers to software applications without retained state information (e.g., state information for closed applications is not stored in a memory of the device). Accordingly, closing an application includes stopping and/or removing application processes for the application and removing state information for the application from the memory of the device. Generally, opening a second application while in a first application does not close the first application. When the second application is displayed and the first application ceases to be displayed, the first application becomes a background application. 
     Attention is now directed towards embodiments of user interfaces (“UI”) and associated processes that are implemented on one or more electronic device(s), such as portable multifunction device  100 , device  300 , or device  500 . 
       FIGS. 6A-6AE  illustrate exemplary user interfaces for initial setup of health monitoring, in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in  FIGS. 7A-7C . The exemplary user interfaces in these figures relate generally to monitoring health using recorded biometric information, and are not limited to a specific type of biometric information.

       FIG. 6A  illustrates a first electronic device  600 A (e.g., a smartphone) with a display  602  and one or more input devices. In some embodiments, the one or more input devices include a touch layer of display  602  for detecting touch input, one or more image sensors  604  (e.g., a camera, a depth sensor), a first mechanical button  606  configured to perform one or more operations (e.g., and including an integrated biometric sensor, such as a fingerprint sensor), and a second mechanical button  608  configured to perform one or more operations. In some embodiments, first electronic device  600 A includes a wireless communication radio (e.g., for LTE, Bluetooth, WiFi connections). In some embodiments, first electronic device  600 A is paired with a second electronic device (e.g., a smartwatch). In some embodiments, the second electronic device corresponds to second electronic device  600 B described below with reference to  FIGS. 6S-6X . 
     In  FIG. 6A , first electronic device  600 A is displaying, on display  602 , a homescreen user interface  610  corresponding to a homescreen of the operating system running on the device. In some embodiments, homescreen user interface  610  includes a plurality of icons corresponding to different applications that are installed on the device, including a health application corresponding to icon  610 A. In some embodiments, the health application can be used to manage a user&#39;s biometric information, such as heart rhythm information and/or heart rate information (e.g., using recorded ECG information). 
     In some embodiments, first electronic device  600 A detects (e.g., via a touch input) a user activation  601  of icon  610 A corresponding to a health application, which includes features concerning management of recordings of biometric information, including ECG information. In response to detecting user activation  601 , first electronic device  600 A launches the health application (e.g., by replacing display of homescreen user interface  610  with a user interface of the health application). 
     In some embodiments, the health application includes an ECG affordance for viewing and managing existing ECG recordings on the device, where the ECG information is recorded using a related ECG application on a second electronic device (e.g., second electronic device  600 B described with reference to  FIGS. 6S-6X ), where the ECG application on the second electronic device (e.g., second electronic device  600 B) is associated with the ECG management features of the health application on first electronic device  600 A. In some embodiments, if the ECG management features have not yet been setup on first electronic device  600 A (e.g., the user has not yet used the ECG recording feature), launching of the ECG management features on the health application (e.g., in response to detecting a user selection of the ECG affordance) causes display of a first page of a tutorial for performing initial setup of the ECG management features of the health application (e.g., as described with reference to  FIG. 6F ). 
     In some embodiments, homescreen user interface  610  includes a paired device application corresponding to icon  610 B and associated with a device paired with first electronic device  600 A (e.g., second electronic device  600 B). In some embodiments, while displaying homescreen user interface  610 , first electronic device  600 A detects (e.g., via a tap input) a user activation  641  of icon  610 B, as shown in  FIG. 6B . 
     In some embodiments, in response to detecting user activation  641 , first electronic device  600 A displays, on display  602 , a main user interface  643  of the paired device application, as shown in  FIG. 6C .

In some embodiments, while displaying main user interface  643  of the paired device application, the device detects (e.g., via a tap input) a user activation  647  of heart application setting affordance  645 G. 
     In some embodiments, in response to detecting user activation  647  of heart application setting affordance  645 G, first electronic device  600 A displays, on display  602 , an application settings page  649  for changing and/or configuring application settings of the corresponding heart application (e.g., the ECG application) on second electronic device  600 B, as shown in  FIG. 6D . In some embodiments, if ECG management features have not yet been setup on first electronic device  600 A, application settings page  649  includes an affordance  651  (e.g., an affordance labelled “Set up ECG functionality” or “Set up ECG application in Health”) for performing initial setup of the ECG management features. In some embodiments, first electronic device  600 A launches the first page of the tutorial (e.g., as described with reference to  FIG. 6F ) in response to detecting a user activation of affordance  651 . 
       FIG. 6E  illustrates first electronic device  600 A displaying, on display  602 , a (selectable) notification  612  indicating (to the user of the device) that an ECG application, which is associated with the health application on first electronic device  600 A, has launched (or is active) on a second electronic device (e.g., second electronic device  600 B). In some embodiments, notification  612  is displayed on a lockscreen user interface of the first electronic device. In some embodiments, notification  612  is displayed in homescreen user interface  610  of the device (e.g., at a top portion of the display). In some embodiments, notification  612  is displayed over a user interface of an application (e.g., email application, web browser application) running on the device (e.g., at a top portion of the display). 
     In some embodiments, notification  612  indicates that initial setup (e.g., onboarding) of the ECG management features of the health application need to be performed in order to utilize ECG features of the application. In some embodiments, while displaying notification  612 , first electronic device  600 A detects (e.g., via a touch input) a user selection  603  of notification  612 . In response to detecting user selection  603 , first electronic device  600 A launches a first page of a tutorial for performing initial setup of the ECG management features and associated ECG application. 
       FIG. 6F  illustrates first electronic device  600 A displaying, on display  602 , a first page  614  of the tutorial for performing initial setup of the ECG management features and associated ECG application. In some embodiments, first page  614  of the tutorial includes a graphical indication region  614 A that graphically indicates (e.g., via a static image, via an animation) a function of the ECG management features and associated ECG application (e.g., recording heart rhythm information and/or heart rate information) and instructions on how to perform the function (e.g., using the associated ECG application on a smartwatch paired to the device). In some embodiments, first page  614  of the tutorial includes a text description region  614 B describing a use of the ECG management features and associated ECG application (e.g., stating “Check your heart rhythm”) and background information relevant to the use of the ECG management features and associated ECG application. 
     In some embodiments, first page  614  of the tutorial includes a date of birth entry field  614 C for receiving a user input corresponding to the user&#39;s date of birth, where the user&#39;s date of birth is used to determine whether the user meets a minimum age requirement (e.g., 22 years of age) to use the features of the ECG application. In some embodiments, date of birth entry field  614 C includes scrollable month, day, and year fields. In some embodiments, first page  614  of the tutorial does not include date of birth entry field  614 C. In some embodiments, first page  614  of the tutorial includes (e.g., in addition to or alternatively to date of birth entry field  614 C) an age restriction message (e.g., stating “You must be 22 years or older”) indicating to the user that the user must meet the minimum age requirement. 
     In some embodiments, first page  614  of the tutorial includes an affordance  614 D for proceeding with the tutorial. In  FIG. 6F , while displaying first page  614  of the tutorial for performing initial setup of the ECG management features and associated ECG application, first electronic device  600 A detects (e.g., via a touch input) a user activation  605  of affordance  614 D for proceeding with the tutorial. In some embodiments, in accordance with a determination that the minimum age requirement is not met (e.g., a determination made in response to detecting user activation  605 ), first electronic device  600 A displays, on display  602 , an error notification (e.g., stating “The ECG application is not intended for use by people under 22”) indicating that the user does not meet the requisite minimum age requirement. In some embodiments, the error notification is overlaid on first page  614  of the tutorial. In some embodiments, while displaying the error notification, the background of the display (displaying first page  614 ) is dimmed (thereby emphasizing the displayed error notification). 
     In some embodiments, in response to detecting user activation  605  (and in accordance with a determination that the minimum age requirement is met), first electronic device  600 A displays, on display  602  (e.g., replaces display of first page  614  with), a second page  616  of the tutorial, as shown in  FIG. 6G . 
       FIG. 6G  illustrates first electronic device  600 A displaying, on display  602 , second page  616  of the tutorial for performing initial setup of the ECG management features and the associated ECG application (e.g., where the associated ECG application is running on or can be launched on a second electronic device, such as second electronic device  600 B). In some embodiments, second page  616  of the tutorial includes an animation region  616 A that graphically indicates (e.g., via a static image, via an animation) example ECG information captured using the application. In some examples, animation region  616 A includes an example tachogram-animation. In some examples, the example tachogram-animation includes one or more objects that continuously move across the animation by tracking the tachogram-like portion of the animation. In some embodiments, second page  616  of the tutorial includes a text description region  616 B that summarizes how the ECG information is captured from the user and how the recorded biometric information can be viewed by the user. In some embodiments, second page  616  of the tutorial includes an affordance  616 C for proceeding with the tutorial. 
     In  FIG. 6G , while displaying second page  616  of the tutorial for performing initial setup of the ECG management features and associated ECG application, first electronic device  600 A detects (e.g., via a touch input) a user activation  607  of affordance  616 C for proceeding with the tutorial. In some embodiments, in response to detecting user activation  607 , the device displays, on display  602  (e.g., replaces display of first page  616  with), a possible results page  618  of the tutorial, as shown in  FIG. 6H . 
       FIG. 6H  illustrates first electronic device  600 A displaying, on display  602 , possible results page  618  of the tutorial for performing initial setup of the ECG management features and associated ECG application. In some embodiments, possible results page  618  includes a plurality of representations of possible evaluation results that can be made based on ECG information recorded using the associated ECG application on a second electronic device (e.g., second electronic device  600 B). 
     In some embodiments, the plurality of representations of possible evaluation results shown in possible results page  618  of the tutorial include possible evaluation results corresponding to heart rhythm and heart rate that are captured from an ECG recording. In some embodiments, a first possible evaluation result is a “regular rhythm” result (or a “normal result”), which corresponds to a result where no abnormal signs were determined from the ECG recording of the user. In some embodiments, a second possible evaluation result is an “abnormal heart rhythm” result (e.g., an “Atrial Fibrillation” result) that corresponds to a result where abnormal heart rhythm signs (and, in some cases, high/low heart rate signs) were determined from the ECG recording of the user. In some embodiments, a third possible evaluation result is an “abnormal heart rate” result (e.g., a “high or low heart rate” result), which corresponds to a result where an unusually (or abnormally) high or low heart rate was determined from the ECG recording of the user (e.g., above 150 BPM or below 50 BPM). In some embodiments, a fourth possible evaluation result is an “inconclusive” result, which corresponds to a result where no evaluation result could be determined from the ECG recording of the user (e.g., because of a poor reading). 
     In some embodiments, as shown in  FIG. 6H , possible results page  618  shows a plurality of representations of possible evaluation results, where not all of the representations are concurrently visible on the display. In  FIG. 6H , a representation  620  of the first evaluation result (a “regular” result) and (a portion of) a representation of  622  of the second evacuation result (a “Atrial Fibrillation” result) is visible on the display. 
     In some embodiments, as shown in  FIG. 6H , each representation of a possible evaluation result shown on possible results page  618  includes an animation region that includes a graphical animation (e.g., a tachogram-like animation, a beating heart animation, one or more objects that continuously/repeatedly move across the tachogram-like animation in a particular frequency) that represents its respective evaluation result and a text region that shows a portion of a text description explaining (medical) characteristics of its respective evaluation result. 
     In  FIG. 6H , representation  620  of a “regular” result includes an animation region  620 A that includes an example animation of a “regular” result and a text region  620 B that shows a portion of a text description explaining characteristics of a “regular” result, and representation  622  of an “Atrial Fibrillation” result includes an animation region  622 A that includes an example animation of an “Atrial Fibrillation” result and a text region  622 B that shows a portion of a text description explaining medical characteristics of an “Atrial Fibrillation” result. In some embodiments, the animations include a beating heart animation and a tachogram-like animation that in combination illustrate a rhythm and rate of heartbeats. 
     In some embodiments, a representation of a possible evaluation result also includes an expand affordance (e.g., a “show more” affordance) for displaying the full text description of the respective evaluation result (e.g., by expanding the text region). In  FIG. 6H , representation  620  of a “regular” result includes an expand affordance  620 C which, when selected (e.g., via a touch input), causes display of the full text description (e.g., which includes additional text information not shown in text region  620 B) about a “regular” result, and representation  622  of an “Atrial Fibrillation” result includes an expand affordance  622 C which, when selected (e.g., via a touch input), causes display of the full text description (e.g., which includes additional text information not shown in text region  622 B) about an “Atrial Fibrillation” result. 
     In  FIG. 6I , while displaying possible results page  618  with representation  620  and representation  622  visible on display  602 , first electronic device  600 A detects a scrolling input  609  (e.g., a scrolling touch gesture on the display). In response to detecting scrolling input  609 , the device scrolls possible results page  618  such that one or more other representations of other possible evaluation results become visible on display  602 , as shown in  FIG. 6J . 
     In  FIG. 6J , representation  624  of a “high or low heart rate” result is fully visible on display  602 . As with the other representations of possible evaluation results, representation  624  includes an animation region  624 A that includes an example graphical animation of a “high or low heart rate” result, a text region  624 B showing a portion of a text description explaining medical characteristics of a “high or low heart rate” result, and an expand affordance  624 C for expanding text region  624 C to fully show all of the text of the text description. Also in  FIG. 6J , representation  622  of an “Atrial Fibrillation” remains fully visible on the display while only a portion of representation  626  of an “inconclusive” result is visible on the display. 
     In  FIG. 6K , while displaying possible results page  618  with representation  620  of a “Atrial Fibrillation” result visible on display  602 , first electronic device  600 A detects (e.g., via a touch input) a user activation  611  of expand affordance  622 C (e.g., because the user wants to view all of the text of the text description describing the “Atrial Fibrillation” result). As shown in  FIG. 6L , in response to detecting user activation  622 C of expand affordance  622 C, first electronic device  600 A expands text region  622 B of representation  622  of the “Atrial Fibrillation” result to display the full text of the text description. In some embodiments, upon expanding the text region, the expand affordance is removed from the representation. In some embodiments, upon expanding the text region, the expand affordance is replaced with a contract affordance (e.g., a “show less” affordance). 
     In  FIG. 6M , while displaying, on display  602 , possible results page  618  with an expanded text region  622 C of representation  622  of an “Atrial Fibrillation” result, first electronic device detects (e.g., via a touch layer of the display) a scrolling input  613  (e.g., a scrolling touch gesture). In response to detecting scrolling input  613 , the device scrolls possible results page  618  such that all of representation  626  of an “inconclusive” result is visible on the display, as shown in  FIG. 6N . 
     In  FIG. 6N , representation  626  of an “inconclusive” result is fully visible on display  602 . As with the other representations of possible evaluation results, representation  626  includes an animation region  626 A that includes an example graphical animation of an “inconclusive” result, a text region  626 B showing a portion of a text description explaining medical characteristics of an “inconclusive” result, and an expand affordance  626 C for expanding text region  626 C to fully show all of the text of the text description. In some embodiments, possible results page  618  includes (e.g., at the bottom of the page), an affordance  628  for proceeding with the tutorial. 
     In some embodiments, as mentioned, the animations (of animations regions  620 A- 626 A) of the plurality of representations  620 - 626  of possible evaluation results on possible results page  618  comprise a beating heart animation and a tachogram-like animation that in combination illustrate a rhythm and rate of heartbeats. In some embodiments, the animations are synchronized. In some examples, each animation comprises repeating loops, where each loop consists of an object (e.g., a circular object) leaving the beating heart animation and moving across the screen while tracking the tachogram-like animation. The repeating loops of the plurality of animations (of representations  620 - 626 ) are synchronized to begin and end at the on synched time intervals. 
     In  FIG. 6N , while displaying, on display  602 , affordance  628  possible results page  618  for proceeding with the tutorial, first electronic device  600 A detects (e.g., via a touch input) a user activation  615  of affordance  628  for proceeding with the tutorial. In response to detecting user activation  615 , first electronic device  600 A displays, on display  602  (e.g., replaces display of possible results page  618  with), a limitations page  630 , as shown in  FIG. 6O . 
     In some embodiments, limitations page  630  indicates to the user (e.g., via a text description) some limitations of evaluation results determined from ECG recordings taken on the second electronic device (e.g., second electronic device  600 B). In some examples, limitations page  630  includes a list  630 A of one or more medical characteristics that cannot be determined from recorded ECG information (e.g., heart attack, blood clots/stroke). In some embodiments, limitations page  630  includes (e.g., at the bottom of the page), an affordance  630 B for proceeding with the tutorial. 
     In  FIG. 6O , while displaying, on display  602 , limitations page  630 , first electronic device  600 A detects (e.g., via a touch input) a user activation  617  of affordance  630 B for proceeding with the tutorial. In some embodiments, in response to detecting user activation  617  of affordance  630 B, the device displays, on display  602 , an instructions page  632 , as shown in  FIG. 6P . 
     In some embodiments, one or more of pages  614 ,  616 ,  618 , and/or  632  of the tutorial (as shown in  FIGS. 6F, 6G, 6H, and 6O , respectively) include a cancel affordance. In some embodiments, upon detecting user selection of a cancel affordance (e.g., in any one of pages  614 ,  616 ,  618 , and/or  632  of the tutorial), first electronic device  600 A displays, on display  602 , a notification  653 , as shown in  FIG. 6Q . In some embodiments, notification  653  includes an indication  653 A (e.g., stating “If you cancel now, you will go through the setup again before you can take an ECG recording”) informing the user that the current progress through the tutorial will be lost and the initial setup process will need to be re-initiated in order for the user to begin taking ECG recordings on second electronic device  600 B. In some embodiments, notification  653  includes a confirmation affordance  653 B (e.g., stating “Set up later”) for confirming the cancellation of the setup process and thus exit the tutorial. In some embodiments, while displaying notification  653 , the background of the display is dimmed (thereby emphasizing notification  653 ). 
       FIG. 6P  shows first electronic device  600 A displaying, on display  602 , instructions page  632 . In some embodiments, instructions page  632  includes a graphical indication region  632 A and a text indication region  632 B that provides instructions for how to proceed with an ECG recording using the second electronic device (e.g., second electronic device  600 B). In some examples, graphical indication region  632 A corresponds to graphical indication region  614 A of first page  614  of the tutorial, and graphically indicates (e.g., via a static image, via an animation) a user taking an ECG recording using the second electronic device (e.g., second electronic device  600 B). In some examples, text indication region  632 B includes a list of instructions including required steps to perform the ECG recording on the second electronic device which can be, for example, a smartwatch with one or more biometric sensors that is paired to first electronic device  600 A (e.g., second electronic device  600 B). 
     In some embodiments, instructions page  632  includes a postpone affordance  632 C (e.g., showing “Take a recording later”) that enables a user to postpone taking the first ECG recording to a later time (and thus allows the user to complete the initial setup process without performing a first ECG recording). In some embodiments, while displaying instructions page  632 , first electronic device  600 A detects (e.g., via a touch input) a user activation  631  of postpone affordance  632 C. 
     In some embodiments, in response to detecting user activation  631  of postpone affordance  632 C, first electronic device  600 A displays, on display  602 , a confirmation notification  633 , as shown in  FIG. 6R  In some embodiments, confirmation notification  633  is overlaid on instructions page  632 . In some embodiments, confirmation notification  633  includes a text indication  633 A indicating to the user that the initial setup process is complete and that the second electronic device (e.g., second electronic device  600 B) is now enabled to perform ECG recordings. In some embodiments, confirmation notification  633  includes a confirm affordance  633 B for acknowledging the completion of the ECG initial setup process (without taking a first ECG recording) and exiting the setup process. In some embodiments, in addition to confirmation notification  633 , the device displays a cancel affordance  635  for exiting dismissing confirmation notification  633  and returning to instructions page  632 . In some embodiments, while displaying confirmation notification  633  (and cancel affordance  635 ), the background of the display (displaying instructions page  632 ) is dimmed (thereby emphasizing the displayed confirmation notification). 
       FIGS. 6S-6X  illustrate second electronic device  600 B (e.g., a smartwatch) having a display  634  and one or more input devices (e.g., including a touch layer of display  634  and one or more mechanical buttons, such as a depressible, rotating crown). In some embodiments, second electronic device  600 B includes one or more biometric sensors (e.g., for recording ECG information, for detecting heart rhythm and heart rate of the user) comprising one or more electrodes integrated in an input device  636  (e.g., a mechanical input device, such as a depressible, rotating crown) of second electronic device  600 B. In some embodiments, the one or more biometric sensors of second electronic device  600 B further comprise one or more electrodes of (e.g., integrated in) a housing portion (e.g., the backplate) of second electronic device  600 B, where the one or more electrodes integrated in the input device operate in conjunction with the one or more electrodes of the housing portion to capture biometric information (e.g., ECG information). Features concerning the one or more biometric sensors of second electronic device  600 B used to capture biometric information (e.g., ECG information) is described in greater detail in Appendix A. In  FIG. 6S , second electronic device  600 B is displaying a watch face user interface  638  (e.g., a time screen of the device). 
     In  FIG. 6S , while displaying lock user interface  638 , second electronic device  600 B detects a user input  619  on input device  636 . In some embodiments, user input  619  is a single press of input device  636  (e.g., such that the force of the press is past a threshold amount to cause a “click” of input device  636 ). In some embodiments, in response to detecting user input  619  on input device  636 , the second electronic device displays, on display  634  (e.g., replaces display of lock user interface  638  with), a home user interface  640  (e.g., corresponding to a home screen of the device, a screen that includes a plurality of icons corresponding to applications installed on the device and can be launched on the device), as shown in  FIG. 6T . Home user interface  640  includes an icon  642  (e.g., an icon graphically depicted with a heart) corresponding to an ECG application installed on the device, where the ECG application on second electronic device  600 B is associated with ECG management features of the health application installed on first electronic device  600 A. 
     In  FIG. 6T , while displaying, on display  634 , icon  642  corresponding to the ECG application, second electronic device  600 B detects (e.g., via a touch input) a user activation  621  of icon  642 . In response to detecting user activation of icon  642 , the device launches and displays the ECG application and displays, on display  634  (e.g., replaces home user interface  640  with), a user interface  644  of the ECG application, as shown in  FIG. 6U . 
     In some embodiments, user interface  644  of the ECG application includes an animation  646  (e.g., a fluid animation) that depicts a particular shape (e.g., a heart). In some examples, as shown in  FIG. 6U , animation  646  comprises a plurality of dynamic objects (e.g., circular objects) that form the particular shape (e.g., a heart), where the shape appears three-dimensional and is visually fluid as the plurality of dynamic objects constantly move while maintaining the structure of the shape. 
     In some embodiments, after a predetermined amount of time (e.g., 5 seconds) has passed from the launch and display of the ECG application on second electronic device  600 B (but the device has not detected any additional inputs from the user), second electronic device  600 B displays, on user interface  644  (and while maintaining display of animation  646 ), a notification message  648  indicating to the user that an action must be performed (by the user) to proceed with recording ECG information using the device (e.g., “Hold your finger on the crown”), as shown in  FIG. 6V . In some embodiments, the user provides a user input (e.g., a contact or touch of a finger) on first input device  636  (e.g., which includes one or more integrated electrodes operating in conjunction with one or more electrodes in a housing portion (e.g., backplate) of second electronic device  600 B) to proceed with the recording of the ECG information, as instructed by notification message  648 . 
       FIG. 6W  illustrates first electronic device  600 A displaying, on display  602 , a recording-in-progress page  694  of the tutorial. In some embodiments, while recording ECG information on second electronic device  600 B, first electronic device  600 A displays, in recording-in-progress page  694  of the health application associated with the ECG application, an indication  696  that the ECG recording is being carried out on second electronic device  600 B. In some examples, indication  696  includes a graphical indication portion (e.g., illustrating an image corresponding to the device being used to perform the recording) and a text indication portion (e.g., stating “Recording in Progress”). 
       FIG. 6W  also illustrates second electronic device  600 B displaying, on display  634 , user interface  644  of the ECG application while the ECG recording (e.g., corresponding to a user input  629  on input device  636 ) is being carried out. In some embodiments, while recording the ECG information, second electronic device  600 B displays a BPM indicator  698  showing the heart rate being detected by the recording. In some embodiments, while recording the ECG information, second electronic device  600 B further displays, over animation  646  (e.g., which, upon recording, transitions form its initial shape, such as a heart, to a grid-like pattern), a tachogram  699  that graphically depicts the ongoing recording. In some embodiments, while recording ECG information, a timer  697  continuously reflects (e.g., by counting down) the remaining time to successfully complete the recording. Features concerning aspects of performing an ECG recording (e.g., on a device such as second electronic device  600 B) is described in greater detail below in  FIGS. 8A-8S, 10A-10J, and 12A-12S . 
       FIG. 6X  illustrates first electronic device  600 A and second electronic device  600 B (immediately) after completing the ECG recording form  FIG. 6W . In some embodiments, upon completing the ECG recording, second electronic device  600 B transmits (e.g., via a Bluetooth connection) data of the ECG recording to first electronic device  600 A. In some embodiments, upon completing the ECG recording, second electronic device  600 B transmits (e.g., via a LTE or WiFi connection) data of the ECG recording to an external server, where the external server is also accessible by first electronic device  600 A. In some embodiments, second electronic device  600 B can record and locally store a plurality of ECG recordings and transmit the plurality of ECG recordings to first electronic device  600 A. 
     In some embodiments, (immediately) after completing the ECG recording, first electronic device  600 A displays a summary page  695  of the tutorial, where summary page  695  includes a representation  693  of the completed recording. In some embodiments, representation  693  includes the evaluation result (e.g., “Regular Rhythm”), the heart rate reading (e.g., in BPM), and a graphical depiction (e.g., a tachogram) of the recording. In some embodiments, summary page  695  of the tutorial includes an affordance  693  for leaving the summary page. In some embodiments, summary page  695  of first electronic device  600 A includes a completion button  691  for exiting the tutorial (after having completed the tutorial). In some embodiments, when the tutorial is completed without the user having taken a first ECG recording, as described with reference to  FIG. 6R , representation  639  of summary page  695  is displayed without an indication of an evaluation result, a heart rate reading, and a graphical depiction of a recording (e.g., the evaluation result, heart rate reading, and graphical depiction fields are blank). 
     In some embodiments, (immediately) after completing the ECG recording, second electronic device  600 B displays at least a portion of a corresponding summary page  689  (e.g., over user interface  644  of the ECG application with animation  646  in its initial pattern (e.g., a fluid heart-shaped pattern, as shown in  FIG. 6V )). In some embodiments, summary page  689  includes the evaluation result (e.g., “Regular Result”) and other related information about the completed recording. In some embodiments, summary page  689  slides onto the display from an edge of the display (e.g., a bottom edge of the display). Features concerning aspects of an ECG recording being performed on a device (e.g., second electronic device  600 B) is described in greater detail below in  FIGS. 12A-12S . 
     In some embodiments, the user can perform a plurality of ECG recordings using the ECG application on second electronic device  600 B. In some embodiments, the plurality of ECG recordings are transmitted from second electronic device  600 B to first electronic device  600 A (or to an external server accessible by first electronic device  600 A) for viewing and management via the ECG management features of the health application on first electronic device  600 A. 
       FIG. 6Y  illustrates first electronic device  600 A displaying, on display  602 , a health data user interface  650  of the health application (e.g., that is associated with the ECG application on second electronic device  600 B) after having performed several ECG readings using second device  600 B. In some embodiments, the health application is accessible via a corresponding icon on a home user interface of the operating system of first electronic device  600 A. 
     In some embodiments, health data user interface  650  of the health application includes an affordance  650 A (e.g., stating “Heart”) for viewing and managing heart health information. In  FIG. 6Y , while displaying health data user interface  650 , first electronic device  600 A detects (e.g., via a touch input) a user activation  623  of affordance  650 A. In response to detecting user activation  623 , the device displays, on display  602 , a heart data user interface  652  corresponding to heart-specific features of the health application. 
     In some embodiments, heart data user interface  652  of the health application on first electronic device  600 A includes a heart rate affordance  654 . In some embodiments, heart rate affordance  654  includes an indication of a range of the user&#39;s heart rate measured (e.g., via second electronic device  600 B) during a certain period of time (e.g., today). In some embodiments, in response to detecting a user selection on heart rate affordance  654 , heart data user interface  652  displays a graphical depiction of the heart rate information summarized by heart rate affordance  654  within a graphical depiction region  656  of the user interface (and further highlights the affordance with a particular visual characteristic, such as a different color, to indicate to the user that the heart rate affordance is currently selected by the user). 
     In some embodiments, heart data user interface  652  of the health application on first electronic device  600 A includes an ECG affordance  658 . In some embodiments, ECG affordance  658  includes a summary of a heart health evaluation result (e.g., a “regular” result, a “Atrial Fibrillation” result, a “high or low heart rate” result, an “inconclusive” result) determined from one or more ECG recordings performed during a certain time period (e.g., today), and a number of recordings taken during the time period (e.g., “2 readings”). In some embodiments, ECG affordance  658  includes an information affordance  658 A for viewing and managing information about existing ECG recordings (e.g., previously performed by the user on second electronic device  600 B). 
     In  FIG. 6Z , while displaying heart data user interface  652  with ECG affordance  658  visible on display  602 , first electronic device  600 A detects (e.g., via a touch input) a user activation  625  of information affordance  658 A of ECG affordance  658 . In response to detecting user activation  625  of information affordance  658 A, first electronic device  600 A displays, on display  602 , an ECG management user interface  660 , as shown in  FIG. 6AA . 
     In some embodiments, ECG management user interface  660  (initially) displays a predetermined number (e.g., three) of representations of the most-recent evaluation result determined from corresponding most-recent ECG recordings performed on second electronic device  600 B. In some embodiments, the representations of the most-recent evaluation results include a graphical portion (e.g., a tachogram) that graphically depicts the recording and a text portion that indicates the type of evaluation result (e.g., a “regular” result, an “Atrial Fibrillation” result, a “high or low heart rate” result, an “inconclusive” result) and a measured heart rate (e.g., in BPM). In some embodiments, the representations of the most-recent evaluation results include an indication of one or more user-specified symptoms associated with the result and/or the number of user-specified symptoms associated with the result. In some embodiments, if the user specified that there are no symptoms to be associated with a result, then a “no symptoms” indication is showed in the corresponding representation of the result. In some embodiments, if the user did not specify any symptoms for a result (or indicate that there are no symptoms for the result), then a symptoms indication is not shown in the corresponding representation of the result. Features related to user selection of symptoms for a respective evaluation result is described in greater detail with reference to  FIGS. 12A-12S . 
     In some embodiments, first electronic device  600 A detects a user activation of ECG affordance  658  at a location on the affordance that does not correspond to information affordance  658 A. In some embodiments, in response to the user activation, first electronic device  600 A replaces display of the heart rate information shown in graphical depiction region  656  of  FIG. 6Z  with heart rhythm information, in a graphical form. 
     In  FIG. 6AA , heart rhythm data user interface  660  shows a representation  662 A corresponding to a most-recent ECG recording, a representation  662 B corresponding to a second-most-recent ECG recording, and a representation  662 C corresponding to a third-most-recent ECG recording. In some examples, representation  662 A corresponds to a “regular” result, with a heart rate measurement of 74 BPM and an indication of 2 symptoms selected for the result. In some examples, representation  662 B corresponds to an “inconclusive” result with no heart rate measurement determined for the result and a “no symptoms” specifically indicated by the user for the result. In some examples, representation  662 C corresponds to an “Atrial Fibrillation” result, with a heart rate measurement of 111 BPM, and no indication or 0 or more selected symptoms because the user did not specify any symptoms or whether there were no symptoms for the result. Further, in some examples, because “Atrial Fibrillation” result is an abnormal result, at least a portion of representation  662 C is highlighted with a particular visual characteristic (e.g., a warning color, such as yellow) that is different from a default visual characteristic. 
     In some embodiments, ECG management user interface  660  also includes a plurality of affordances for viewing additional/different representations of additional/different past evaluation results and sorting/filtering the existing evaluation results. In some examples, ECG management user interface  660  includes a “show all results” affordance  664 A (e.g., which also indicates the number of associated existing recordings) for displaying representations of all past ECG recordings performed by the user. In some examples, ECG management user interface  660  includes a first filter affordance  664 B for displaying (e.g., filtering the existing recordings to show) representations of all of the existing ECG recordings corresponding to a “regular” result (e.g., representation  662 A). In some examples, ECG management user interface  660  includes a second filter affordance  664 C for displaying (e.g., filtering the existing recordings to show) representations of all of the existing ECG recordings corresponding to a “Atrial Fibrillation” result (e.g., representation  662 C). In some examples, ECG management user interface  660  includes a second filter affordance  664 C for displaying (e.g., filtering the existing recordings to show) representations of all of the existing ECG recordings corresponding to a “Atrial Fibrillation” result (e.g., representation  662 C). In some examples, ECG management user interface  660  includes a third filter affordance  664 D for displaying (e.g., filtering the existing recordings to show) representations of all of the existing ECG recordings corresponding to both a “Atrial Fibrillation” result and a “high heart rate” (e.g., a heart rate over 150 BPM) result. In some examples, ECG management user interface  660  includes a fourth filter affordance  664 E for displaying (e.g., filtering the existing recordings to show) representations of all of the existing ECG recordings corresponding to both a “high heart rate” (e.g., a heart rate over 150 BPM) result and a “low heart rate” (e.g., a heart rate below 50 BPM) result. In some examples, ECG management user interface  660  includes a fifth filter affordance  664 F for displaying (e.g., filtering the existing recordings to show) representations of all of the existing ECG recordings corresponding to a “high heart rate” (e.g., a heart rate over 150 BPM) result. In some examples, ECG management user interface  660  includes a sixth filter affordance  664 G for displaying (e.g., filtering the existing recordings to show) representations of all of the existing ECG recordings corresponding to a “low heart rate” (e.g., a heart rate below 50 BPM) result. In some examples, ECG management user interface  660  includes a seventh filter affordance  664 H for displaying (e.g., filtering the existing recordings to show) representations of all of the existing ECG recordings corresponding to an “inconclusive” result (e.g., because the measured heart rate was too high or too low to determine an evaluation result, because the captured ECG information was incomplete and/or unreadable to determine an evaluation result). 
     In  FIG. 6AB , while displaying ECG management user interface  660  on display  602 , first electronic device  600 A detects (e.g., via a touch input) a user selection  627  of representation  662 A (corresponding to a “regular” result, with a heart rate measurement of 74 BPM and an indication of 2 symptoms selected for the result). In response to detecting user selection  627 , first electronic device  600 A displays, on display  602  (e.g., replaces display of ECG management user interface  660  with), a details page  666  corresponding to the selected evaluation result, as shown in  FIG. 6AC . 
     In some embodiments, a details page includes one or more descriptive items (e.g., a tachogram, a type of evaluation result, a measured BPM of the result, a presence of lack of presence of Atrial Fibrillation, one or more selected symptoms) associated with the selected evaluation result. Details page  666  corresponds to the evaluation result of representation  662 A (from  FIG. 6AB ), which is a “regular” result. In some examples, details page  666  includes an animation  668 A that graphically depicts the recording of this regular result (e.g. a tachogram representing the measured heart rhythm and heart rate data), an indication  668 B that indicates the determined evaluation result of the recording (a “regular” result), an indication  668 C that indicates whether one or more specific medical characteristics (e.g., Atrial Fibrillation) was determined from the ECG recording (e.g., “This recording did not show signs of Atrial Fibrillation”), and an indication  668 D that indicates (or lists) the user-specified symptoms associated with the ECG recording (e.g., “chest pain” and “shortness of breath”). 
     In some embodiments, a details page (e.g., details page  666 ) includes an information affordance  670  which causes display of a text description explaining general medical characteristics of the corresponding evaluation result. In some examples, the text description corresponds to the full text description displayed in an expanded text region of possible results page  618  of the tutorial, as described above with reference to  FIGS. 6H-6N . 
     In some embodiments, a details page (e.g., details page  666 ) includes a share affordance  672  for sharing a document (e.g., a PDF document) summarizing the corresponding ECG recording with an indicated external source (e.g., transmitting the document to an email account). An exemplary document generated for transmittal to the indicated external source is shown in  FIG. 6AD . In some embodiments, in response to detecting a user selection of share affordance  672 , first electronic device  600 A generates the document and enables the user to input an intended recipient (e.g., an email account) for (automatic) transmittal of the generated document to the intended recipient. 
     In some embodiments, a details page (e.g., details page  666 ) includes an emergency contact affordance  674  (e.g., for seeking immediate medical care, for contacting  911 ). In some embodiments, in response to detecting a user selection of emergency contact affordance  674 , first electronic device  600 A initiates a phone call to an emergency contact (e.g.,  911 ). 
     In some embodiments, a details page (e.g., details page  666 ) includes a metadata list  676  indicating one or more information items related to the ECG recording (e.g., the device used to perform the recording, the time of the recording, an operating system of the device used to perform the recording). 
     In some embodiments, a details page (e.g., details page  666 ) includes a delete affordance  678  for deleting the ECG recording (e.g., from local storage on first electronic device  600 A, from local storage on the second electronic device used to perform the recording, such as second electronic device  600 B, from remote storage on an external server). 
       FIG. 6AD  illustrates a document  680  (e.g., a PDF document) generated in response to detecting a user selection of share affordance  672  from details page  666 . In some examples, document  680  includes basic user information  682  (e.g., name of the user, date of birth of the user). In some examples, document  680  includes an evaluation result  684  of the ECG recording (e.g., a “regular” result, an “Atrial Fibrillation” result, a “high or low heart rate” result, an “inconclusive” result). In some examples, document  680  includes a heart rate measurement  686  of the ECG recording (e.g., in BPM). In some examples, document  680  includes a time  694  of the ECG recording. In some examples, document  680  includes a list of symptoms  688  selected by the user for the ECG recording. In some examples, document  680  includes a tachogram  690  of the ECG recording (e.g., an unfiltered, full tachogram). In some examples, document  680  includes legend information  692  describing tachogram  690 . 
     In some embodiments, first electronic device  600 A can enable and disable (e.g., via the health application and/or the paired device application described with reference to  FIG. 6A ) ECG recording functionality on second electronic device  600 B. In some embodiments, when the ECG application is launched on second electronic device  600 B while ECG recording functionality is disabled (by first electronic device  600 A), second electronic device  600 B displays, on display  634 , an error notification user interface  637  indicating to the user (e.g., via text stating “The ECG application has been remotely disabled”) that an ECG recording cannot be performed because ECG recording functionality has been disabled (by first electronic device  600 A), as shown in  FIG. 6AE . 
       FIGS. 7A-7C  are a flow diagram illustrating a method for initial setup of heath monitoring, in accordance with some embodiments. Method  700  is performed at a first electronic device (e.g.,  100 ,  300 ,  500 ,  600 A) with a display and one or more input devices (e.g., a biometric sensor, a touch layer of the display), where the first electronic device is paired with a second electronic device (e.g.,  600 B). Some operations in method  700  are, optionally, combined, the orders of some operations are, optionally, changed, and some operations are, optionally, omitted. 
     As described below, method  700  provides an intuitive way for managing health monitoring. The method reduces the cognitive burden on a user for managing health monitoring, thereby creating a more efficient human-machine interface. For battery-operated computing devices, enabling a user to manage health monitoring faster and more efficiently conserves power and increases the time between battery charges. 
     The first electronic device (e.g.,  600 A) displays ( 706 ), on the display (e.g.,  602 ), a first portion of a tutorial (e.g.,  614 ,  616 ,  618 ,  630 ,  632 ) for using a function (e.g., measuring heart rhythm information (an electrocardiogram) or heart rate information (BPM)) of the second electronic device (e.g.,  600 B) (e.g., a function performed using one or more biometric sensors of the second electronic device). Displaying the first portion of the tutorial for using the function of the second electronic device reduces the number of inputs needed by the user to initialize the first electronic device (e.g.,  600 A) and the second electronic device (e.g.,  600 B) for using the function by providing guidance on how to successfully complete the initialization process and providing important background information about using the function (e.g., without forcing the user to, without any guidance, test the function in order to learn how to use the function). Reducing the number of inputs needed to perform an operation enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, prior to displaying, on the display (e.g.,  602 ), the first portion of the tutorial (e.g.,  614 ,  616 ,  618 ,  630 ,  632 ) for using the function of the second electronic device (e.g.,  600 B), the first electronic device (e.g.,  600 A) receives ( 702 ) (e.g., via a wireless communication radio of the first electronic device), from the second electronic device (e.g.,  600 B), a second indication that an application configured to control the use of the function on the second electronic device (e.g.,  600 B) is opened (e.g., launched, initiated) on the second electronic device (e.g.,  600 B). Displaying the second indication that the application configured to control the use of the function on the second device (e.g.,  600 B) is opened provides the user with feedback about the current state of the second electronic device and visually indicates to the user that the second electronic device is ready for the operation that uses the function. Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, in response to receiving the second indication that the application configured to control the use of the function on the second electronic device (e.g.,  600 B) is opened, the first electronic device (e.g.,  600 A) displays ( 704 ), on the display (e.g.,  602 ), a notification (e.g.,  612 ) corresponding to the tutorial for using the function of the second electronic device. Displaying, on the display (e.g.,  602 ), the notification corresponding to the tutorial for using the function of the second electronic device provides the user with feedback about the current state of the second electronic device and visually indicates to the user a tutorial is available on the first electronic device (e.g.,  600 A) to proceed with configuring the use of the function on the second electronic device. Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the notification (e.g.,  612 ) informs the user that the application has launched on the second electronic device (e.g.,  600 B) and that the user can view the tutorial for using the function of the second electronic device (e.g.,  600 B) that relates to the launched application. In some embodiments, the first electronic device (e.g.,  600 A) displays, on the display (e.g.,  602 ), the tutorial in response to detecting user selection (e.g., a tap gesture) of the notification (e.g.,  612 ). Displaying, on the display (e.g.,  602 ), the tutorial in response to detecting the user selection of the notification (e.g.,  612 ) improves visual feedback by indicating to the user that the tutorial corresponding to the displayed notification has launched on the first electronic device (e.g.,  600 A). Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the first electronic device (e.g.,  600 A) displays the first portion of the tutorial (e.g.,  614 ,  616 ,  618 ,  630 ,  632 ) in response to an input received while displaying a user interface (e.g.,  643 ) configured to modify one or more settings of the second electronic device (e.g.,  600 B). Displaying the first portion of the tutorial in response to an input received while displaying a user interface configured to modify one or more settings of the second electronic device improves visual feedback by indicating to the user that the displayed tutorial is associated with an application that can be used on the second electronic device. Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     The first electronic device (e.g.,  600 A) detects ( 708 ), via the one or more input devices, a request to proceed with the tutorial (e.g., a user&#39;s tap input on one or more “continue” buttons,  614 C,  616 C,  628 ,  630 B). 
     In response to detecting the request to proceed with the tutorial, the first electronic device (e.g.,  600 A) displays ( 710 ), on the display (e.g.,  602 ), instructions to perform an operation (e.g., capturing/recording biometric data) on the second electronic device (e.g.,  600 B) that involves the function of the second electronic device (e.g.,  600 B). Displaying, on the display (e.g.,  602 ) of the first electronic device (e.g.,  600 A), instructions to perform the operation on the second electronic device (e.g.,  600 B) that involves the function of the second electronic device improves visual feedback to the user indicating that the operation corresponding to the tutorial needs to be performed on the second electronic device (e.g., and not on the first electronic device). Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the operation on the second electronic device (e.g.,  600 B) includes capturing biometric data (e.g., using a biometric sensor of the second electronic device). In some embodiments, the biometric data that is captured by the second electronic device (e.g.,  600   b ) is heart-related data (e.g., ECG data, BPM data). 
     In some embodiments, the first portion of the tutorial includes a plurality of graphical indications of possible results (e.g.,  620 ,  622 ,  624 ,  626 , heart rhythm evaluation results, heart rate measurements) of the operation (e.g., an ECG recording operation, a BPM measurement operation) performed on the second electronic device (e.g.,  600   b ). 
     In some embodiments, the operation is evaluating a medical characteristic (of the user) including a heart rhythm evaluation (e.g., an electrocardiogram reading) and a heart rate evaluation (e.g., a BPM reading), and the possible results are selected from the group consisting of: a normal result (e.g., for the heart rhythm evaluation and/or for the heart rate evaluation), an abnormal heart rhythm pattern result (e.g., signs of Atrial Fibrillation), an abnormal heart rate result (e.g., BPM above a high threshold or below a low threshold, such as BPM over 150 or BPM below 50), and an inconclusive result (e.g., based on a poor reading). 
     In some embodiments, while displaying at least a first possible result (e.g.,  624 ) of the possible results, where the first possible result includes a portion of (the text of) a first result summary (e.g.,  624 B, text summarizing medical characteristics related to the respective result), the first electronics device (e.g.,  600 A) detects, via the one or more input devices, a user activation of an expand affordance (e.g.,  624 C) associated with the first result summary. Providing the expand affordance while displaying at least the first possible result of the possible results, where the first possible result includes the portion of the first result summary improves visual feedback by indicating to the user that only a portion of the first result summary is not currently displayed, and that the expand affordance can be selected to cause all of the first result summary to be displayed. Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. In some embodiments, in response to detecting the user activation of the expand affordance (e.g.,  624 C), the first electronic device (e.g.,  600 A) displays, on the display (e.g.,  602 ), all of (the text of) the first result summary. 
     In some embodiments, the plurality of graphical indications of possible results (e.g.,  620 ,  622 ,  624 ,  626 ) include a first graphical indication (e.g.,  620 ) that includes display of a first animation (e.g.,  620 A) related to a first possible result and a second graphical indication (e.g.,  622 ) that includes a second animation (e.g.,  622 A) related to a second possible result, and the first animation and the second animation are synchronized. In some embodiments, the first animation and the second animations are dynamic animations that include a beating heart animation and tachogram-like features that depict a rhythm and rate of a heartbeat. 
     In some embodiments, while displaying, on the display (e.g.,  602 ), the plurality of graphical indications (e.g.,  620 ,  622 ,  624 ,  626 ) of possible results, the first electronic device (e.g.,  600 A) detects, via the one or more input devices, a scrolling gesture (e.g., a scroll on the touch layer of the display). In some embodiments, in response to detecting the scrolling gesture, the first electronic device (e.g.,  600 A) scrolls the plurality of graphical indications (e.g.,  620 ,  622 ,  624 ,  626 ). In some embodiments, the first electronic device (e.g.,  600 A) displays, on the display (e.g.,  602 ), a third graphical indication (e.g.,  624 ) that includes a third animation (e.g.,  624 A) related to a third possible result, where the third animation is synchronized with the first animation (e.g.,  620 A) and the second animation (e.g.,  622 A). 
     In some embodiments, the first animation (e.g.,  620 A) includes a first portion of the animation (e.g., beating heart) that is animated at a fixed location and a second portion of the animation (e.g., dot) that animatedly moves from the fixed location to a second location. In some embodiments, the object follows a tachogram-like pattern when leaving the heart-shaped animation. In some embodiments, a first object of the first dynamic animation and a second object of the second dynamic animation repeatedly (continuously) leave their respective heart-shaped animations synchronously. Providing an animation (e.g., first animation  620 A) for a graphical indication (e.g., one of  620 ,  622 ,  624 ,  626 ) of possible results improves visual feedback by indicating to the user that the operation discussed by the tutorial relates to heart monitoring, as shown in the animation, and providing visual guidance as to how each possible result derived from the heart monitoring operation differ. Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the first portion of the tutorial (e.g.,  614 ,  616 ,  618 ,  630 ,  632 ) includes a limitations indication (e.g.,  630 , explaining to the user the limits of the operation, showing a list of medical characteristics that cannot be determined by the operation) that includes one or more medical characteristics that cannot be derived from the operation. Providing the limitations indication (e.g.,  630 ) in the first portion of the tutorial improves visual feedback by visually indicating to the user, during the setup process (such that the user is more likely to be made aware), the one or more medical characteristics that cannot be derived from the operation. Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     The first electronic device  600 A receives ( 716 ) (e.g., after the user has carried out the instructions on the second electronic device (e.g.,  600 B), via a wireless radio communication between the devices), from the second electronic device (e.g.,  600 B), an indication that the instructions have been carried out (on the second electronic device). 
     In some embodiments, prior to receiving (e.g., via a wireless radio communication between the devices), from the second electronic device (e.g.,  600 B), the indication that the instructions have been carried out, the first electronic device (e.g.,  600 A) receives ( 712 ), from the second electronic device (e.g.,  600 B) (e.g., via the wireless radio communication between the devices), an indication that the instructions have begun to be carried out (on the second electronic device). In some embodiments, in response to receiving the indication that the instructions have begun to be carried out, the first electronic device (e.g.,  600 A) displays ( 714 ), on the display (e.g.,  602 ), an indication (e.g.,  820 , a “recording in progress” page of the tutorial) that the instructions are being carried out on the second electronic device. Displaying, on the display (e.g.,  602 ), the indication that the instructions are being carried out on the second electronic device (e.g.,  600 B) in response to receiving the indication that the instructions have begun to be carried out enhances visual feedback by visually indicating to the user that the operation is being successfully carried out on the second electronic device (and thus that the setup process is proceeding along as intended). Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In response to receiving the indication that the instructions have been carried out, the first electronic device (e.g.,  600 A) displays ( 718 ), on the display (e.g.,  602 ), a second portion of the tutorial (e.g.,  828 , a “completion” page) that is different from the first portion. Displaying, on the display (e.g.,  602 ), the second portion of the tutorial that is different from the first portion in response to receiving the indication that the instructions have been carried out improves visual feedback by indicating to the user that the operation performed on the second electronic device has been completed (e.g., and thus that the setup process has been successfully completed and that the operation is available for future use). Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the second portion of the tutorial (e.g.,  828 , a “completion” page) includes a graphical animation (e.g., a tachogram-like animation) that represents (biometric) information obtained from the operation on the second electronic device. 
     In some embodiments, after displaying, on the display (e.g.,  602 ), the second portion of the tutorial (e.g.,  828 ), the first electronic device (e.g.,  600 A) displays ( 720 ), on the display (e.g.,  602 ), a user interface of a health application (e.g.,  650 ,  656 ,  660 ). 
     In some embodiments, the first electronic device (e.g.,  600 A) detects ( 722 ), via the one or more input devices, a user activation of an affordance (e.g.,  658 A, an ECG affordance) for viewing recorded biometric information (e.g., recorded ECG and BPM readings). In some embodiments, the affordance (e.g.,  658 A) for viewing existing recordings of biometric information includes an indication of a number of existing recordings of biometric information (e.g., a number of recorded ECG and/or BPM readings). Providing the indication of the number of existing recordings of biometric information in the affordance for viewing existing recordings of biometric information improves visual feedback by conveniently conveying to the user the number of existing recordings that can be viewed in the health application. Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, in response to detecting the user activation of the affordance (e.g.,  658 A) for viewing existing recordings of biometric information, the first electronic device (e.g.,  600 A) displays ( 724 ), on the display (e.g.,  602 ), a first plurality of representations (e.g.,  662 A- 662 C) corresponding to existing recordings of biometric information. In some embodiments, a representation of an existing recording of biometric information (e.g.,  662 A- 66 C) includes a tachogram corresponding to the recording, an evaluation result of the recording, the number of symptoms (if any) associated with the recording, and a heart rate (BPM) recorded by the recording. Displaying, on the display (e.g.,  602 ), the first plurality of representations (e.g.,  662 A- 662 C) corresponding to existing recordings of biometric information in response to detecting the user activation of the affordance for viewing existing recordings of biometric information improves visual feedback by conveniently providing to the user representations of some existing recordings (e.g., some of the most recent recordings) that may be of most relevance to the user. Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the first plurality of representations of existing recordings of biometric information (e.g.,  662 A- 66 C) include a first representation (e.g.,  662 C) corresponding to a first existing recording with an abnormal evaluation result (e.g., an abnormal heart rhythm, such as a Atrial Fibrillation condition), where the first representation (e.g.,  662 C) includes an indication of the abnormal evaluation result that is displayed with a first visual characteristic (e.g., highlighted with a warning color, such as yellow). In some embodiments, the plurality of representations of existing recordings of biometric information (e.g.,  662 A- 66 C) include a fourth representation (e.g.,  662 A) corresponding to a fourth existing recording with a normal evaluation result, and the fourth representation includes an indication of the normal evaluation result that is displayed with a second visual characteristic (e.g., a default color) different from the first visual characteristic. 
     In some embodiments, the first plurality of representations of existing recordings of biometric information (e.g.,  662 A- 66 C) include a second representation (e.g.,  662 A,  662 B) corresponding to a second existing recording associated with user-specified symptoms, where the second representation includes an indication of the number of user-specified symptoms associated with the second existing recording (e.g., “2 Symptoms,” “No Symptoms”). In some embodiments, the first plurality of representations of existing recordings of biometric information (e.g.,  662 A- 66 C) include a third representation (e.g.,  662 C) corresponding to a third existing recording not associated with any user-specified symptoms (e.g., because the user did not specify any symptoms for the recording), where the third representation does not include an indication of user-specified symptoms associated with the third existing recording. Providing the second representation (e.g.,  662 A,  662 B) corresponding to the second existing recording associated with user-specified symptoms improves visual feedback by conveniently indicating to the user whether or not (and if yes, how many) symptoms were previously selected by the user for the recording (e.g., thereby allowing the user to quickly recognize whether a particular recording by correspond to a more serious reading, if there are many user-specified symptoms associated with the recording). Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. In some embodiments, the user-specified symptoms cannot be modified after the symptoms have been specified and saved (by the user on the second electronic device). 
     In some embodiments, further in response to detecting the user activation of the affordance (e.g.,  658 A) for viewing recorded biometric information, the first electronic device (e.g.,  600 A) displays ( 726 ), on the display (e.g.,  602 ), a plurality of sort affordances (e.g.,  664 A- 664 H, to filter visible recordings by the type of evaluation results, such as normal results, abnormal heart rhythm results, or abnormal heart rate results) including a first sort affordance and a second sort affordance. In some embodiments, the first sort affordance includes an indication of a number of existing recordings of biometric information associated with the first type of evaluation result, and the second sort affordance includes an indication of a number of existing recordings of biometric information associated with the second type of evaluation result. In some embodiments, the first electronic device (e.g.,  600 A) detects ( 728 ), via the one or more input devices, a user activation of the first sort affordance. 
     In some embodiments, in response to detecting the user activation of the first sort affordance, the first electronic device (e.g.,  600 A) displays ( 730 ), on the display (e.g.,  602 ), a second plurality of representations (e.g., by replacing the first plurality of representations) corresponding to existing recordings of biometric information, where the second plurality of representations correspond to existing recordings associated with a first type of evaluation result (e.g., a normal result, an abnormal heart rhythm result, an abnormal heart rate result, an inconclusive result). In some embodiments, the first electronic device (e.g.,  600 A) detects ( 732 ), via the one or more input devices, a user activation of the second sort affordance. 
     In some embodiments, in response to detecting user activation of the second sort affordance, the first electronic device (e.g.,  600 A) displays ( 734 ), on the display (e.g.,  602 ), a third plurality of representations (e.g., by replacing the first plurality of representations) corresponding to existing recordings of biometric information, where the third plurality of representations correspond to existing recordings associated with a second type of evaluation result. In some embodiments, the second and third plurality of representations have corresponding overlapping existing recordings, if one or more existing recordings are associated with both the first type of evaluation result and the second type of evaluation result. 
     In some embodiments, the first electronic device (e.g.,  600 A) detects, via the one or more input devices, a user selection of a first representation (e.g.,  662 A) of the first plurality of representations (e.g.,  662 A- 66 C) corresponding to a first existing recording corresponding to a first evaluation result. In some embodiments, in response to detecting the user selection of the first representation, the first electronic device (e.g.,  600 A) displays a first details view (e.g.,  666 ) of the first existing recording. 
     In some embodiments, while displaying the first details view (e.g.,  666 ) of the first existing recording, the first electronic device (e.g.,  600 A) detects, via the one or more input devices, a user activation of an information affordance (e.g.,  670 , an “i” icon). In some embodiments, in response to detecting the user activation of the information affordance (e.g.,  670 ), the first electronic device (e.g.,  600 A) displays, on the display (e.g.,  602 ), a result summary (e.g., text summarizing medical characteristics related to the respective result) and an animation from a corresponding possible result from the first portion of the tutorial (e.g., where the possible result from the tutorial corresponds to the evaluation result of the first existing recording). 
     In some embodiments, while displaying the first details view (e.g.,  666 ) of the first existing recording corresponding to a first evaluation result, the first electronic device (e.g.,  600 A) detects, via the one or more input devices, a user activation of an export affordance (e.g.,  672 , marked as “share as a PDF”). In some embodiments, in response to detecting user activation of the export affordance (e.g.,  672 ), the first electronic device (e.g.,  600 A) creates (and subsequently transmitting to an intended recipient) a document that includes information concerning the first existing recording (e.g., information about the user, date and time of the recording, a tachogram of the (ECG) recording, the evaluation result of the recording). In some embodiments, the biometric data (e.g., ECG data) of the recording is included in the document without any filtering (of the data from the recording). (Automatically) generating and (automatically) transmitting the document (to an intended recipient) in response to detecting the user activation of the information affordance reduces the number of inputs needed from the user to create a transmittal document summarized a recording and subsequently transmitting the document to an intended recipient. Reducing the number of inputs needed to perform an operation enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. In some embodiments, the user-specified symptoms cannot be modified after the symptoms have been specified and saved (by the user on the second electronic device).

For brevity, these details are not repeated below. 
       FIGS. 8A-8S  illustrate exemplary user interfaces for recording biometric information for use in health monitoring. The user interfaces in these figures are used to illustrate the processes described below, including the processes in  FIGS. 9A-9B . The exemplary user interfaces in these figures relate generally to monitoring health using recorded biometric information, and are not limited to a specific type of biometric information. Only for the sake of convenience, the exemplary user interfaces in these figures are described with reference to a type of biometric information—electrocardiogram (hereinafter “ECG”) information. 
       FIG. 8A  illustrates a first electronic device  800 A (e.g., corresponding to second electronic device  600 B). In some embodiments, first electronic device  800 A is a smartwatch. In some embodiments, first electronic device  800 A has a display  802  and one or more input devices (e.g., including a touch layer of display  802  and one or more mechanical buttons, such as a rotating crown). In some embodiments, first electronic device  800 A includes one or more biometric sensors (e.g., for recording ECG information, for detecting heart rhythm and heart rate of the user) comprising one or more electrodes integrated in an input device  804  (e.g., a mechanical input device, such as a depressible, rotating crown) of first electronic device  800 A. In some embodiments, the one or more biometric sensors of first electronic device  800 A further comprise one or more electrodes of (e.g., integrated in) a housing portion (e.g., the backplate) of first electronic device  800 A, where the one or more electrodes integrated in the input device operate in conjunction with the one or more electrodes of the housing portion to capture biometric information (e.g., ECG information). Features concerning the one or more biometric sensors of first electronic device  800 A used to capture biometric information (e.g., ECG information) is described in greater detail in Appendix A. 
       FIG. 8A  illustrates first electronic device  800 A displaying, on display  802 , a user interface  806  of an ECG application (e.g., corresponding to user interface  644  of the ECG application described with reference to  FIGS. 6A-6AE ). 
     In some embodiments, similar to user interface  644 , user interface  806  includes an animation  808  (e.g., a fluid animation, corresponding to animation  646  of user interface  644 ) that depicts a particular shape (e.g., a heart). In some examples, as shown in  FIG. 8A , animation  808  comprises a plurality of dynamic objects (e.g., circular objects) that form the particular shape (e.g., a heart), where the shape appears three-dimensional and is visually fluid as the plurality of dynamic objects constantly move while maintaining the structure of the shape. 
     In some embodiments, while displaying animation  808  in the particular shape (e.g., a heart), user interface  806  displays a notification message  810  (e.g., corresponding to notification message  648  of user interface  644 ) indicating to the user that an action must be performed (by the user) on the device to proceed with an ECG recording (to capture heart rhythm and heart rate information). In some embodiments, notification message  810  instructs the user of the type of input (e.g., a touch or contact on the input device that is below a threshold amount such that the input does not “click” the input device) and that the input must be maintained on the input device (e.g., for the duration of the recording). 
     In some embodiments, prior to displaying user interface  806  of the ECG application (e.g., while first electronic device  800 A is displaying a user interface of a different application or the display is off), the device detects (e.g., using a second biometric sensor that measures heart rate information without user input) heart rate information of the user for a period of time (e.g., 1 minute) and determines that the detected heart rate is above a threshold rate (e.g., above 150 BPM). In some embodiments, upon detecting that the detected heart rate is above the threshold rate for at least the period of time, the device displays, on display  802 , a notification informing the user of the (continuous) high heart rate and requests that the user monitor his or her heart health using the ECG application. 
     In  FIG. 8B , while displaying, on display  802 , user interface  806  of the ECG application, first electronic device  800 A detects a user input  801  on input device  804  in accordance with the instructions from notification message  810 . In some embodiments, user input  801  is a continuous touch or contact on the input device that is below a threshold amount (e.g., an input that does not “click” the input device). In some embodiments, upon detecting (and continuing to detect) user input  801  on input device  804 , the plurality of dynamic objects forming animation  808  transition from their initial pattern (e.g., of a shape) towards a different pattern, as shown in  FIG. 8B . In some embodiments, upon detecting (and continuing to detect) user input  801 , first electronic device  800 A ceases to display, on display  802 , notification message  810 . 
       FIG. 8C  illustrates first electronic device  800 A continuing to detect user input  801  on input device  804 . In some embodiments, while continuing to detect user input  801  on input device  804 , the plurality of dynamic objects forming animation  808  continue to transition toward and begin to form a different pattern (e.g., a grid of a tachogram). In some embodiments, first electronic device  800 A displays, in user interface  806  (e.g., below animation  808 ), a timer  810  (e.g., a countdown timer of a predetermined amount of time, such as 30 seconds) that indicates the amount of time remaining to complete the ECG recording. In some embodiments, first electronic device  800 A displays, in user interface  806  (e.g., below timer  810 ), a notification message  812  instructing the user to maintain the input on input device  804  (e.g., stating “Touch the crown and try to hold still”) to successfully complete the ECG recording. 
       FIG. 8D  illustrates first electronic device  800 A further continuing to detect user input  801  on input device  804 . In some embodiments, as the user continues to maintain user input  801  on input device  804 , first electronic device  800 A begins recording ECG information. In some embodiments, while recording the ECG information, the device displays, in user interface  806 , a BPM indicator  814  showing the heart rate being detected by the recording. In some embodiments, while recording ECG information, the device further displays, over animation  808  (which, during a recording, forms a grid-like pattern), a tachogram  816  that graphically depicts the ongoing recording. In some embodiments, while recording ECG information, timer  810  continuously reflects (e.g., by counting down) the remaining time to successfully complete the recording. 
       FIG. 8E  illustrates a second electronic device  800 B (e.g., corresponding to first electronic device  600 A described with reference to  FIGS. 6A-6AE ). In some embodiments, second electronic device  800 B is a smartphone that is paired with first electronic device  800 A (e.g., via a short-range wireless communication radio connection, such as a Bluetooth connection). In  FIG. 8E , second electronic device  800 B is displaying, on a display  818 , a user interface  820  of a health application that is associated with the ECG application running on first electronic device  800 A. In some embodiments, while recording ECG information on first electronic device  800 A, second electronic device  800 B displays, in user interface  820  of the health application associated with the ECG application, an indication  822  that ECG recording is on-going on first electronic device  800 A. In some examples, indication  822  includes a graphical indication portion (e.g., illustrating an image corresponding to the device being used to perform the recording) and a text indication portion (e.g., stating “Recording in Progress”). 
       FIG. 8F  illustrates first electronic device  800 A displaying, on display  802 , user interface  806  of the ECG application while the device is continuing to perform the ECG recording from  FIG. 8E . In  FIG. 8F , during the ECG recording, the device detects that user input  801  on input device  804  is lost (e.g., because the user lifted the finger used for the input away from input device  804 ). In some embodiments, in response to detecting that the user input on input device  804  is lost, the device displays, in user interface  806 , a message indication  824  (e.g., stating “Please keep your finger on the crown”) requesting that the user restore the user input on input device  804  in order to continue with the ECG recording. In some embodiments, while the user input is lost on input device  804 , the device continues to count down towards the end of the recording (which is indicated by timer  810 ). In some embodiments, while the user input is lost on input device  804 , the device pauses the recording until the user input is restored on input device  804 . In some embodiments, in response to detecting that the user input is lost on the input device  804 , the first electronic device  800 A resets the value of timer  810  (e.g., to the initial 30 seconds value) and restarts the recording if the user input is restored (e.g., restored within a predetermined time). 
     In some embodiments, if the user input on input device  804  is not restored within a time limit (e.g., 5 seconds), first electronic device  800 A (automatically) terminates the recording and transitions back to the initial user interface of  FIG. 8A . In some embodiments, if the user input on input device  804  is restored within the time limit (e.g., 5 seconds), the device (automatically) continues the recording (e.g., and re-starts the timer, if paused). In some embodiments, the time limit (e.g., 5 seconds) for restoring the input is reset once the user input is restored. That is, if the user input is lost for a second time during a recording, the device (automatically) terminates the recording and transitions back to the initial user interface of  FIG. 8A  if the full time limit (e.g., 5 seconds) lapses without the user restoring the user input. 
     In  FIG. 8G , first electronic device  800 A again detects user input  801  on input device  804  before the time limit (e.g., 5 seconds) has lapsed from when the user input was lost in  FIG. 8F . Because the user input on input device  804  was restored prior to expiration of the time limit (e.g., 5 seconds), the device continues the ECG recording without (automatically) terminating the recording. 
       FIG. 8H  illustrates first electronic device  800 A continuing to detect user input  801  on input device  804  and the device continuing the ECG recording from  FIG. 8G . In some embodiments, timer  810  continues to indicate the time remaining to complete the recording (e.g., “1 second”). 
       FIG. 8I  illustrates user interface  806  of the ECG application upon completion of the recording (which is indicated by timer  810  showing no time remaining). In some embodiments, upon completion of a recording, the plurality of dynamic objects forming animation  808  re-transitions from the grid-like pattern during the recording toward their initial pattern (e.g., of a shape, such as heart) prior to the recording. 
       FIG. 8J  illustrates first electronic device  800 A and second electronic device  800 B (immediately) after completing the ECG recording. In some embodiments, upon completing the ECG recording, first electronic device  800 A transmits (e.g., via a Bluetooth connection) data of the ECG recording to second electronic device  800 B. In some embodiments, upon completing the ECG recording, first electronic device  800 A transmits (e.g., via a LTE or WiFi connection) data of the ECG recording to an external server, where the external server is also accessible by second electronic device  800 B. In some embodiments, first electronic device  800 A can record and locally store a plurality of ECG recordings and transmit the plurality of ECG recordings to second electronic device  800 B. 
     In some embodiments, (immediately) after completing the ECG recording, first electronic device  800 A displays, on display  802 , user interface  806  of the ECG application with animation  808  in its initial pattern (e.g., a fluid heart-shaped pattern) and at least a portion of a summary page  826  that includes an evaluation result (e.g., “Regular Result”) and other related information about the completed recording. In some embodiments, summary page  826  slides onto the display from an edge of the display (e.g., a bottom edge of the display). 
     In some embodiments, (immediately) after completing the ECG recording, second electronic device  800 B displays, in the health application, a summary page  828  of the health application associated with the ECG application on second electronic device  800 A, where summary page  828  includes a representation  830  of the completed recording. In some embodiments, representation  830  includes the evaluation result (e.g., “Regular Rhythm”), the heart rate reading (e.g., in BPM), and a graphical depiction (e.g., a tachogram) of the recording. In some embodiments, summary page  828  includes an affordance  832  for leaving the summary page. 
       FIG. 8K  illustrates first electronic device  800 A displaying, on display  802 , (at least a portion of) summary page  826  corresponding to the ECG recording. In some embodiments, summary page  826  includes a summary region  834  that includes an indication  834 A of the evaluation result (e.g., “Regular Rhythm”) and an indication  834 B of the heart rate reading (e.g., in BPM). In some embodiments, summary region  834  also includes a information affordance  836  for viewing a detailed description about the respective evaluation result (e.g., where the detailed description corresponds to the text description shown in possible results page  618  of the tutorial described with reference to  FIGS. 6A-6AE ). In some embodiments, summary page  826  includes an indication  838  of whether a particular medical characteristic (e.g., signs of Atrial Fibrillation, signs of irregular heart rhythm) was determined from the recording. In some embodiments, summary page  826  includes a symptoms region  840  that includes an affordance  842  for associating one or more symptoms to the reading. In some embodiments, while displaying summary page  826 , the device maintains display of animation  808  (e.g., in its initial shape as shown in  FIG. 8A ) in the background of the summary page (e.g., in a lighter shade so that the summary page is easily legible to the user). 
       FIGS. 8L-8O  illustrate a plurality of different error notification messages that can be displayed in user interface  806  of the ECG application while recording ECG information. In  FIG. 8L , while performing a first ECG recording corresponding to a user input  803  on input device  804 , first electronic device  800 A detects movement of the user input on input device  804  above a threshold amount (e.g., there is movement with the user&#39;s contact with input device  804 , where the amount of the movement is above a threshold amount of movement). In some embodiments, in response to detecting the movement of the user input on input device  804  above the threshold amount (e.g., for at least a period of time, such as 5 seconds), first electronic device  800 A displays (e.g., below timer  810 ), a notification message  844  (e.g., stating “Try not to move your arm”) requesting that the user restrict movement of user input  803  during the recording. 
     In  FIG. 8M , a period of time (e.g., 5 seconds) after displaying notification message  844 , and while continuing to perform the first ECG recording corresponding to user input  803  on input device  804 , first electronic device  800 A continues to detect movement of the user input on input device  804  above the threshold amount. In some embodiments, in response to continuing (e.g., for another period of time, such as 5 seconds, after displaying the initial notification message  844 ), first electronic device  800 A displays (e.g., below timer  810 , replaces display of notification message  844  with) a notification message  846  (e.g., stating “It may help to rest your arm on a table or in your lap”) indicating that the user could try resting his/her arm on a surface to stabilize the user input on input device  804 . 
     In  FIG. 8N , while performing a second ECG recording corresponding to a user input  805  on input device  804 , first electronic device  800 A detects a press input on input device  804 , where the force of the press is above a threshold amount (e.g., such that the user “clicks” input device  804 ). In some embodiments, in response to detecting the press input on input device  804 , first electronic device  800 A displays (e.g., below timer  810 ) a notification message  848  (e.g., stating “You do not need to click the crown”) informing the user that input device  804  does not need to be “clicked” to perform the recording, and/or informing the user that less force can be used for the input on input device  804  to successfully complete the recording. 
     In  FIG. 8O , while performing a third ECG recording corresponding to a user input  807  on input device  804 , first electronic device  800 A detects (e.g., as in  FIG. 8F ), that user input  807  on input device  804  is lost (e.g., because the user lifted the finger used for the input away from input device  804 ). In some embodiments, in response to detecting that the user input on (e.g., the user&#39;s contact with) input device  804  is lost, first electronic device  800 A displays (e.g., below timer  810 ) a notification message  850  (e.g., corresponding to notification message  824 , stating “Please keep your finger on the crown”) requesting that the user restore the user input on input device  804  to continue with the ECG recording. 
       FIG. 8P  illustrates first electronic device  800 A displaying, on display  802 , user interface  806  of the ECG application while performing an ECG recording corresponding to a user input  809  on input device  804  (e.g., after an initial threshold time period (e.g., 5 seconds) has passed from the initiation of the recording). In some embodiments, the required duration of an ECG recording is 30 seconds. As indicated by timer  810  (e.g., showing “20 seconds”) in  FIG. 8P , 10 seconds have passed since the initiation of the recording. In some embodiments, first electronic device  800 A displays a tachogram  816  corresponding to a visual illustration of the ECG recording. 
     In  FIG. 8Q , first electronic device  800 A loses detection of user input  809  on input device  804 . In some embodiments, in response to (e.g., immediately in response to or within a short period of time, such as 1 second) losing detection of the user input on input device  804 , first electronic device  800 A resets the ECG recording (e.g., terminates the previous recording and prepares to start a new recording), as indicated by timer  810  (e.g., which now shows “30 seconds,” the full duration of a recording. In some embodiments, first electronic device  800 A causes the remaining time indicated in timer  810  to “rewind” back to (e.g., count back up to) the initial duration in response to losing detection of the user input on input device  804 . In some embodiments, first electronic device  800 A causes tachogram  816  to show a “silent” tachogram, thereby further indicating to the user that ECG information is not being captured. 
     In some embodiments (e.g., after resetting the recording), upon detecting that the user input on input device  804  has not been restored for a at least a predetermined period of time (e.g., 2.5 seconds), first electronic device  800 A displays, in user interface  806  of the ECG application, a notification message  852  (e.g., stating “Hold your finger on the crown”) requesting that the user restore the input on input device  804 , as shown in  FIG. 8R . In some embodiments (e.g., in addition to displaying notification message  852 ), the devices displays (e.g., re-displays) animation  808  in its initial pattern (e.g., a heart shape), as first described with reference to  FIG. 8A . In some embodiments, the plurality of dynamic objects forming animation forming animation  808  dynamically transition from the grid-like pattern of  FIG. 8Q  to its initial pattern (e.g., a heart shape) of  FIG. 8R . 
     In some embodiments (e.g., after resetting the recording), upon detecting that the user input on input device  804  has not been restored for at least the predetermined period of time (e.g., 2.5 seconds), first electronic device  800 A alternatively displays, in user interface  806  of the ECG application, animation  808  in its initial pattern (e.g., a heart shape) but forgoes displaying notification message  852 , as shown in  FIG. 8S . 
     In some embodiments, first electronic device  800 A first transitions form the user interface of  FIG. 8Q  to the user interface of  FIG. 8R  upon detecting that the user input on input device  804  has not been restored for a first predetermined period of time (e.g., 2.5 seconds), and then transitions from the user interface of  FIG. 8R  to the user interface of  FIG. 8S  upon detecting that the user input on input device  804  has not been restored for a second predetermined period of time (e.g., which is the same as or different from the first predetermined period of time) after the first predetermined period of time has passed. 
       FIGS. 9A-9B  are a flow diagram illustrating a method recording biometric information for health monitoring, in accordance with some embodiments. Method  900  is performed at a first electronic device (e.g.,  100 ,  300 ,  500 ,  600 B,  800 A) with a display and one or more input devices including a biometric sensor (e.g., a set of one or more sensors, such as electrodes, configured to measure electrical activity correlated to portions of the heart of a user of the electronic device). Some operations in method  900  are, optionally, combined, the orders of some operations are, optionally, changed, and some operations are, optionally, omitted. 
     As described below, method  900  provides an intuitive way for managing health monitoring. The method reduces the cognitive burden on a user for managing health monitoring, thereby creating a more efficient human-machine interface. For battery-operated computing devices, enabling a user to manage health monitoring faster and more efficiently conserves power and increases the time between battery charges. 
     The first electronic device (e.g.,  800 A) displays ( 908 ), on the display (e.g.,  802 ), a first user interface (e.g., of a health monitoring application or a health data measurement application, main user interface  806  of the ECG application, as shown in  FIG. 8A ) indicating that the first electronic device (e.g.,  800 A) is ready to detect biometric information (e.g., ECG data, BPM data, heart-related data). Displaying, on the display (e.g.,  802 ), the first user interface indicating that the first electronic device (e.g.,  800 A) is ready to detect biometric information provides visual feedback by indicating that biometric information is ready to be recorded on the first electronic device. Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, prior to displaying the first user interface (e.g.,  806  of  FIG. 8A ), the first electronic device (e.g.,  800 A) displays ( 902 ) a homescreen (e.g.,  1012 ) that includes an application affordance (e.g.,  1014 ) corresponding to a health monitoring application (e.g., for monitoring heart health, such as the ECG application). Displaying, on the display (e.g.,  802 ), the application affordance corresponding to the health monitoring application on the homescreen provides visual feedback by indicating to the user that the health monitoring application can be accessed from the homescreen of the first electronic device (e.g.,  800 A). Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. In some embodiments, the first electronic device (e.g.,  800 A) detects ( 904 ), via the one or more input devices, a user activation of the application affordance. In some embodiments, in response to detecting the user activation of the application affordance, the first electronic device (e.g.,  800 A) displays ( 906 ), on the display (e.g.,  802 ), the first user interface (e.g.,  806 ). 
     In some embodiments, a (text) notification (e.g.,  810 ) requesting the first input on the biometric sensor (e.g.,  804 ) is displayed in the first user interface (e.g.,  806  of  FIG. 8A ) after a predetermined amount of time (e.g., 5 seconds) has passed after detecting the user activation of the application affordance. In some embodiments, the notification (e.g.,  810 ) instructs the user to place a finger on the first input device (e.g.,  804 ). Providing the notification (e.g.,  810 ) requesting the first input on the biometric sensor in the first user interface after the predetermined amount of time has passed after detecting the user activation of the application affordance provides the user with more control of the device by helping the user avoid unintentionally an unintended operation (e.g., by selecting a wrong button or affordance) and simultaneously allowing the user to recognize that the input on the biometric sensor is required to proceed with the recording operation. Providing additional control of the device (without cluttering the user interface with additional displayed controls) enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the recorded biometric information includes an electrocardiogram recording derived from the biometric information detected by the biometric sensor (e.g.,  804 ). In some embodiments, the biometric sensor (e.g.,  804 ) is a contact-based sensor, and the first input with the biometric sensor (e.g.,  804 ) satisfies the first criteria when a contact (e.g., from a finger of a user) is detected on the biometric sensor (e.g.,  804 ). 
     The first electronic device (e.g.,  800 A) detects ( 910 ) a first input with the biometric sensor (e.g.,  804 ) that satisfies first criteria (e.g., user contact with the biometric sensor, movement below a threshold, electrical interference below a threshold). 
     In response to detecting the first input with the biometric sensor (e.g.,  804 ), the first electronics device (e.g.,  800 A) starts ( 912 ) to record biometric information detected by the biometric sensor (e.g.,  804 ). Also in response to detecting the first input with the biometric sensor (e.g.,  804 ), the first electronic device (e.g.,  800 A) displays ( 914 ), on the display (e.g.,  802 ), a second user interface (e.g.,  806  of  FIG. 8D ) (e.g., a measurement page of a health application) that is different from the first user interface (e.g.,  806  of  FIG. 8A ), where the second user interface (e.g.,  806  of  FIG. 8D ) includes an indication of progress (e.g.,  810 ) in recording the biometric information. In some embodiments, the indication of progress (e.g.,  810 ) is a countdown timer (e.g., showing a countdown in seconds from a predetermined start time to zero). Displaying, on the second user interface (e.g.,  806  of  FIG. 8D ), the indication of progress (e.g.,  810 ) in recording the biometric information improves visual feedback by indicating to the user that the recording is being carried out and the duration for which the user must maintain the input to continue with the recording. Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     After recording at least a portion of the biometric information, the first electronic device (e.g.,  800 A) detects ( 912 ), via the one or more input devices, that the first criteria are no longer met (e.g., user contact with the biometric sensor  804  is lost). 
     In response to detecting that the first criteria are no longer met for a first period of time (e.g., 5 seconds), the first electronic device (e.g.,  800 A) resets ( 918 ) the indication of progress (e.g.,  810 ) in recording the biometric information and maintaining display of the second user interface (e.g.,  806  of  FIG. 8D ). Resetting the indication of progress (e.g.,  810 ) while maintaining display of the second user interface (e.g.,  806  of  FIG. 8D ) in response to detecting that the first criteria are no longer met for a first period of time provides the user with more control of the device by helping the user avoid unintentionally leaving the health monitoring application while simultaneously allowing the user to easily continue with the recording without having to manually re-initiate the recording or the health monitoring application. Providing additional control of the device (without cluttering the user interface with additional displayed controls) enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In response to detecting that the first criteria are no longer met for a second period of time that is longer than the first period of time (e.g., longer than 5 seconds), the first electronic device (e.g.,  800 A) replaces ( 920 ) display of the second user interface (e.g.,  806  of  FIG. 8D ) with the first user interface (e.g.,  806  of  FIG. 8A ). Replacing display of the second user interface (e.g.,  806  of  FIG. 8D ) with the first user interface (e.g.,  806  of  FIG. 8A ) in response to detecting that the first criteria are no longer met for a second period of time that is longer than the first period of time improves visual feedback by visually indicating to the user that the recording has been stopped and that the a new recording can be re-initiated by the user. Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the first user interface (e.g.,  806  of  FIG. 8A ) includes a graphical animation (e.g., of a shape, such as a heart,  808  of  FIG. 8A ) indicating (to the user) that the first electronic device (e.g.,  800 A) is ready to detect biometric information, where the graphical animation is comprised of a plurality of moving objects (e.g.,  808 , circular dots) forming a first shape (e.g., a heart shape). Providing the graphical animation (e.g.,  808  of  FIG. 8A  to the user that the first electronic device (e.g.,  800 A) is ready to detect biometric information provides visual feedback about the current state of the application and indicates to that the user can proceed with a recording. Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the plurality of moving objects (e.g.,  808 ) of the graphical animation transitions from the first shape (e.g., a heart shape) to a second shape (e.g., a grid shape) different from the first shape as the display transitions from the first user interface to the second user interface. 
     In some embodiments, further in response to detecting that the first criteria are no longer met for the first period of time, the first electronic device (e.g.,  800 A) transitions the plurality of moving objects (e.g.,  808 ) of the graphical animation to an interstitial shape between the first shape (e.g., a heart shape) and the second shape (e.g., a grid shape). 
     In some embodiments, while displaying the second user interface (e.g.,  806  of  FIG. 8D ) and recording the biometric information (e.g., heart rhythm information, heart rate information), the first electronic device (e.g.,  800 A) displays, within the graphical animation that is in the second shape (e.g.,  808  of  FIG. 8D , a grid), a visual representation of the recorded biometric information, where the recorded biometric information is filtered and scaled such that the visual representation of the recorded biometric information can be displayed within the graphical animation. Displaying the visual representation of the recorded biometric information while displaying the second user interface (e.g.,  806  of  FIG. 8D ) and recording the biometric information improves visual feedback by allowing the user to view the current state and progress of the recording and indicating to the user that the recording is being carried out. Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the second user interface (e.g.,  806  of  FIG. 8D ) includes a (dynamic) graphical representation (e.g., a dynamic tachogram-like animation) that corresponds to a visualization of the biometric information from the recorded biometric information and a (countdown) timer (e.g.,  810 ) indicating (to the user) the amount of time remaining to complete the recording of the biometric information. In some embodiments, the biometric information that is recorded is heart-related data, and the graphical representation is a dynamic animation that includes a tachogram to reflect the data obtained from the biometric sensor (e.g.,  804 ). 
     In some embodiments, while recording the biometric information, the first electronic device (e.g.,  800 A) detects, via the one or more input devices, that second criteria are met. In some embodiments, in response to detecting that the second criteria are met, the first electronic device (e.g.,  800 A) displays, in the second user interface (e.g.,  806  of  FIG. 8D , below the indication of progress  810 ), a (text) notification (e.g.,  824 ) related to the second criteria. Displaying, on the second user interface (e.g.,  806  of  FIG. 8D ), the notification (e.g.,  824 ) related to the second criteria in response to detecting that the second criteria are met provides the user with more control of the device by quickly indicating to the user that one or more actions need to be taken by the user to maintain a recording. Providing additional control of the device (without cluttering the user interface with additional displayed controls) enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the second criteria is met when an amount of movement (of the device caused by the user) above a threshold is detected, and the notification (e.g.,  844 ) indicates (to the user) that the amount of movement should be decreased. In some embodiments, the notification (e.g.,  844 ) notifies the user that too much movement is detected. In some embodiments, the notification (e.g.,  844 ) further notifies the user to constrain his/her movements. 
     In some embodiments, the second criteria is met when the amount of movement (of the device caused by the user) above the threshold is detected for at least a third period of time, and the notification (e.g.,  846 ) indicates (to the user) that the first electronic device should be moved to a resting position (e.g., on a table). In some embodiments, if the first electronic device is a smartwatch, the notification (e.g.,  846 ) instructs the user to rest his/her arm on a table. 
     In some embodiments, the second criteria is met when a second input (e.g., a press input, a click input) having a type that is different from the type of the first input is detected on a first input device (e.g.,  804 , a crown, a mechanical button, a rotating button), and the notification (e.g.,  848 ) indicates (to the user) that the second input should not be repeated on the first input device. In some embodiments, the biometric sensor includes one or more electrodes integrated in the first input device (e.g.,  804 ) (e.g., operating in conjunction with one or more electrodes integrated in a housing portion (e.g., backplate) of the first electronic device (e.g.,  800 A). In some embodiments, the second input is a press/click input on the first input device (e.g.,  804 ), and the notification (e.g.,  848 ) notifies that the user should not press/click the first input device (e.g.,  804 ). 
     In some embodiments, the second criteria is met when the first input is no longer detected (e.g., discontinued, interrupted) by the biometric sensor (e.g.,  804 ) when recording of the biometric information is not yet completed, and the notification (e.g.,  850 ) indicates (to the user) that the first input should be maintained on the biometric sensor (e.g.,  804 ). In some embodiments, the first electronic device (e.g.,  800 A) detects that the first input is no longer detected when the user discontinues contact with the biometric sensor (e.g.,  804 ) while recording of the biometric information is still ongoing. In some embodiments, the notification (e.g.,  850 ) instructs the user to re-establish contact with (e.g., by placing his/her finger back on) the biometric sensor (e.g.,  804 ). 
     In some embodiments, after taking a first recording of first biometric information and a second recording of second biometric information different from the first biometric information (e.g., where the first recording and the second recording are different recordings that were taken at different times), the first electronic device (e.g.,  800 A) transmits ( 922 ), to a second electronic device (e.g.,  800 B, a smartphone paired with the smartwatch), the recorded first biometric information and the recorded second biometric information. 
     In some embodiments, (e.g., while not displaying the application corresponding to the first and second user interfaces on the display) the first electronic device (e.g.,  800 A) detects ( 924 ) (e.g., via a second biometric sensor that measures heart rate information without user input) heart rate information (of the user) for a predetermined amount of time. In some embodiments, in accordance with a determination that the detected heart rate information meets a first condition (e.g., above a threshold, such as 150 BPM, above a threshold for a certain amount of time), the first electronic device (e.g.,  800 A) displays ( 926 ), on the display (e.g.,  802 ), a notification indicating a high heart rate. Displaying, on the display (e.g.,  802 ), the notification indicating the high heart rate in accordance with the determination that the detected heart rate information meets the first condition improves visual feedback by quickly informing the user of the high heart rate. Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the first electronic device (e.g.,  800 A) detects ( 928 ), via the one or more input devices, a user activation of the notification. In some embodiments, in response to detecting the user activation of the notification, the first electronic device (e.g.,  800 A) displays ( 930 ), on the display (e.g.,  802 ), the first user interface (e.g.,  806  of  FIG. 8A , so that the user can check his/her electrocardiogram recording using the application corresponding to the first user interface). Displaying, on the display (e.g.,  802 ) the first user interface (e.g.,  806  of  FIG. 8A ) in response to detecting the user activation of the notification reduces the number of inputs needed to launch the application corresponding to the first user interface when the device detects the high heart rate of the user. Reducing the number of inputs needed to perform an operation enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently.

       FIGS. 10A-10J  illustrate exemplary user interfaces for health monitoring, in accordance with some embodiments. The exemplary user interfaces in these figures are used to illustrate the processes described below, including the processes in  FIG. 11 . The exemplary user interfaces in these figures relate generally to monitoring health using recorded biometric information, and are not limited to a specific type of biometric information. Only for the sake of convenience, the exemplary user interfaces in these figures are described with reference to a type of biometric information—electrocardiogram (hereinafter “ECG”) information. 
       FIG. 10A  illustrates a first electronic device  1000  (e.g., corresponding to second electronic device  600 B, first electronic device  800 A). In some embodiments, first electronic device  1000 A is a smartwatch. In some embodiments, first electronic device  1000 A has a display  1002  and one or more input devices (e.g., including a touch layer of display  1002  and one or more mechanical buttons, such as a rotating crown). In some embodiments, first electronic device  1000  includes one or more biometric sensors (e.g., for recording ECG information, for detecting heart rhythm and heart rate of the user) comprising one or more electrodes integrated in an input device  1004  (e.g., a mechanical input device, such as a depressible, rotating crown) of first electronic device  1000 . In some embodiments, the one or more biometric sensors of first electronic device  1000  further comprise one or more electrodes of (e.g., integrated in) a housing portion (e.g., the backplate) of first electronic device  1000 , where the one or more electrodes integrated in the input device operate in conjunction with the one or more electrodes of the housing portion to capture biometric information (e.g., ECG information). Features concerning the one or more biometric sensors of first electronic device  1000  used to capture biometric information (e.g., ECG information) is described in greater detail in Appendix A. 
     In some embodiments, first electronic device  1000  is configured to detect and respond to activation of input device  1004  (e.g., respond by performing a first predefined operation or a second predefined operation), where the activation is different from and independent of the capture of biometric information (e.g., ECG information). 
       FIG. 10A  illustrates first electronic device  1000  displaying, on display  1002 , a user interface  1006  of an ECG application (e.g., corresponding to user interface  644  of the ECG application described with reference to  FIGS. 6A-6AE  and user interface  806  of the ECG application described with reference to  FIGS. 8A-8S ). In some embodiments, the ECG application is configured to cause first electronic device  1000  to capture biometric information without detecting the activation of input device  1004 . 
     In some embodiments, user interface  1006  includes an animation  1008  (e.g., a fluid animation, corresponding to animation  646  of user interface  644  and animation  808  of user interface  806 ) that depicts a particular shape (e.g., a heart). In some examples, as shown in  FIG. 10A , animation  1008  comprises a plurality of dynamic objects (e.g., circular objects) that form the particular shape (e.g., a heart), where the shape appears three-dimensional and is visually fluid as the plurality of dynamic objects constantly move while maintaining the structure of the shape. In some examples, the plurality of dynamic objects forming animation  1008  have a consistent visual characteristic (e.g., the same color). 
     In some embodiments, while displaying animation  1008  in the particular shape (e.g., a heart), user interface  1006  displays a notification message  1010  (e.g., corresponding to notification message  648  of user interface  644  and notification message  810  of user interface  806 , stating “Hold your finger on the crown”) indicating to the user that an action must be performed (by the user) on the device to proceed with recording the user&#39;s ECG information. In some embodiments, notification message  1010  instructs the user of the type of input (e.g., a touch or contact on input device  1004  that is below a threshold amount such that the input does not “click” input device  1004 ) and that the input must be maintained on input device  1004  (e.g., for the duration of the recording). 
     In some embodiments, while displaying user interface  1006  of the ECG application as shown in  FIG. 10A , first electronic device  1000  detects a press input  1001  on input device  1004 , where the press input is an input on input device  1004  with a pressing force above a threshold amount such that the input “clicks” input device  1004 . 
     In some embodiments, in response to detecting press input  1001  while displaying user interface  1006  of the ECG application as shown in  FIG. 10A , first electronic device  1000  displays, on display  1002  (e.g., replaces display of user interface  1006  with), a home user interface  1012  (e.g., a main user interface of the operating system of the device), as shown in  FIG. 10B . In some embodiments, home user interface  1012  includes a plurality of icons corresponding to different applications installed on the device, including an icon  1014  corresponding to the ECG application. 
       FIG. 10C  illustrates first electronic device  1000 , while displaying user interface  1006  of the ECG application, detecting (and maintaining) a user input  1003  (e.g., a continuous touch or contact of a finger on input device  1000 ) on input device  1004  to begin an ECG recording (e.g., as described with reference to  FIGS. 8A-8C ). In some embodiments, upon beginning the ECG recording, the dynamic plurality of objects (e.g., circular objects) of animation  1008  transitions from their initial fluid shape in  FIG. 10A  to a grid-like shape. In some embodiments, upon beginning the ECG recording, the device displays, in user interface  1006 , a timer  1016  (e.g., below animation  1010 ) indicating the remaining amount of time to complete the recording (e.g., initially 30 seconds). In some embodiments, upon beginning the ECG recording, the device displays, in user interface  1006  (e.g., below timer  1016 ), a notification message  1018  (e.g., stating “Touch the crown and try to hold still”) requesting that the user maintain (a stable) user input  1003  on input device  1004  during the recording of the ECG information. 
       FIG. 10D  illustrates first electronic device  1000  recording ECG information from the user, where a initial threshold time period (e.g., 5 seconds) has not passed since the initiation of the recording (e.g., as indicated by timer  1016 , which shows that 3 seconds have passed since the initiation of the recording). In some embodiments, while the initial threshold time period has not yet passed, first electronic device  1000  detects a press input  1005  on input device  1004 , where the press input is an input on input device  1004  with a pressing force above a threshold amount such that the input “clicks” input device  1004 . In some embodiments, in response to detecting press input  1005  on input device  1004  while the initial threshold time period has not yet passed, first electronic device  1000  (automatically) terminates the recording and displays user interface  1006  of the ECG application as shown in  FIG. 10A . 
       FIG. 10E  illustrates first electronic device recording ECG information from the user, where the initial threshold time period (e.g., 5 seconds) has passed since the initiation of the recording (e.g., as indicated by timer  1016 , which shows that 6 seconds have passed since the initiation of the recording). In some embodiments, after the initial threshold time period has passed, first electronic device  1000  detects a press input  1007  (e.g., similar to press input  1005 ) on input device  1004 , where the press input is an input on input device  1004  with a pressing force above a threshold amount such that the input “clicks” input device  1004 . In some embodiments, in response to detecting press input  1007  on input device  1004  after the initial threshold time period (e.g., 5 seconds) has passed, first electronic device  1000  does not terminate the recording. In some embodiments, (instead of terminating the recording) first electronic device  1000  displays, in user interface  1006 , a notification message  1020  (e.g., stating “You do not need to click the crown”) indicating that there is no need to “click” input device  1004  during the recording or to successfully complete the recording. 
     In some embodiments, after detecting press input  1007  on input device  1004  after the initial threshold time period (e.g., 5 seconds) has passed, in response to which first electronic device  1000  does not terminate the recording, the device detects a second press input (e.g., similar to press input  1007 ) after detecting press input  1007  but before a predetermined amount of time (e.g., 2.5 seconds) has passed since detecting press input  1007 . In some embodiments, in response to detecting the second press input after detecting press input  1007  but before the predetermined amount of time (e.g., 2.5 seconds) has passed since detecting press input  1007 , first electronic device  1000  (automatically) terminates the recording and displays user interface  1006  of the ECG application as shown in  FIG. 10A . 
     In some embodiments, after detecting press input  1007  on input device  1004  after the initial threshold time period (e.g., 5 seconds) has passed, in response to which first electronic device  1000  does not terminate the recording, the device detects a second press input (e.g., similar to press input  1007 ) after detecting press input  1007  and after a predetermined amount of time (e.g., 2.5 seconds) has passed since detecting press input  1007 . In some embodiments, (instead of terminating the recording) first electronic device  1000  displays, in user interface  1006 , a notification message  1020  (e.g., stating “You do not need to click the crown”) indicating that there is no need to “click” input device  1004  during the recording or to successfully complete the recording. In summary, in some embodiments and while recording is underway, termination of recording occurs if two inputs are received within a predetermined period (e.g., within rapid succession (e.g., within 2.5 seconds)). In contrast, in some embodiments, if two inputs are received but spaced apart by more than the predetermined period (e.g., within 2.5 seconds) the recording is not cancelled. 
       FIG. 10F  illustrates first electronic device  1000  performing an ECG recording on the ECG application with, as indicated by timer  1016  of user interface  1006  (e.g., showing “20 Seconds”), 20 seconds remaining to complete the recording. In  FIG. 10F , the initial threshold time period (e.g., 5 seconds) has passed since the initiation of the recording. In some embodiments, after the initial threshold time period (e.g., 5 seconds) has passed since the initiation of the recording, first electronic device  1000  detects a user input a press input  1009  (or a press-and-hold input) on input device  1004 , where the press input is an input on input device  1004  with a pressing force above a threshold amount such that the input “clicks” input device  1004  (e.g., and the pressing force is maintained for at least a period of time, such as 1 second). In some embodiments, in response to detecting press input  1009  on input device  1004  after the initial threshold time period (e.g., 5 seconds) has passed, first electronic device  1000  does not terminate the recording and displays, in user interface  1006 , a notification message  1020  (e.g., stating “You do not need to click the crown”) indicating that there is no need to “click” input device  1004  during the recording or to successfully complete the recording. 
     In some embodiments, at least a predetermined amount of time (e.g., 5 seconds) after detecting user input  1009 , first electronic device  1000  detects a press a press-and-hold input  1011  on input device  1004 , where the press-and-hold input is an input on input device  1004  with a pressing force above a threshold amount such that the input “clicks” input device  1004 , and input device  1004  is “clicked” for at least a threshold period of time (e.g., 1 second). In some embodiments, in response to detecting press-and-hold input  1011  on input device  1004  while the initial threshold time period has not yet passed, first electronic device  1000  (automatically) displays, on display  1002  (e.g., replaces display of user interface  1006  of the ECG application with), a user interface  1022  of a virtual assistant (e.g., a virtual assistant controlled by the operating system of the device), as shown in  FIG. 10G . 
       FIGS. 10H-10J  illustrate first electronic device  1000  receiving an electronic communication (e.g., a phone call, a text message, an email message) while the device is performing an ECG recording. In  FIG. 10H , the received electronic communication (e.g., a text message from “Jane Appleseed”) is represented as a notification  1026  corresponding to the electronic communication. The electronic communication (represented as notification  1026 ) is received while first electronic device  1000  is performing an ECG recording (e.g., from user input  1013  on input device  1004 . 
       FIG. 10I  illustrates first electronic device  1000  displaying, on display  1002 , a summary page  1028  of the ECG recording (e.g., corresponding to summary page  826  described with reference to  FIGS. 8J-8K ) upon completing the ECG recording. In  FIG. 10J , upon (or subsequent to) completing the recording (and displaying summary page  1028  corresponding to the recording), first electronic device  1000  displays, on display  1002 , a notification alert  1030  corresponding to the electronic communication (e.g., the text message from “Jane Appleseed”) that was received during the recording. In some embodiments, if one or more additional electronic communications were received during the recording, the device also provides one or more notification alerts corresponding to the received electronic communications upon (or subsequent to) completing the recording. 
     In some embodiments, upon (or prior to) beginning an ECG recording, first electronic device  1000  automatically disables a wireless communication radio (e.g., a LTE connection) of the device. In some embodiments, upon (or in response to) completing the ECG recording, first electronic device  1000  automatically re-enables the wireless communication radio on the device. 
     In some embodiments, upon (or prior to) beginning an ECG recording, first electronic device  1000  automatically disables a haptic feedback controller (e.g., a haptic actuator) of the device. In some embodiments, upon (or in response to) completing the ECG recording, first electronic device  1000  automatically re-enables the haptic feedback controller of the device. 
       FIG. 11  is a flow diagram illustrating a method for using an input device for health monitoring, in accordance with some embodiments. Method  1100  is performed at a device (e.g.,  100 ,  300 ,  500 ,  600 B,  800 A,  1000 ) with a display and one or more input devices including a first input device with an integrated biometric sensor (e.g., a rotatable and depressible watch crown with integrated biometric sensors comprising one or more electrodes for detecting characteristics of the user&#39;s heart). Some operations in method  1100  are, optionally, combined, the orders of some operations are, optionally, changed, and some operations are, optionally, omitted. 
     As described below, method  1100  provides an intuitive way for managing health monitoring. The method reduces the cognitive burden on a user for managing health monitoring, thereby creating a more efficient human-machine interface. For battery-operated computing devices, enabling a user to manage health monitoring faster and more efficiently conserves power and increases the time between battery charges. 
     The first electronic device (e.g.,  1000 ) displays ( 1102 ), on the display (e.g.,  1002 ), a user interface (e.g.,  1006  of  FIG. 10A ) of an application (e.g., a health application, such as a health monitoring application or a health data measurement application) for capturing biometric information (e.g., ECG data, BPM data, heart-related data) from the biometric sensor (e.g.,  1004 ). 
     In some embodiments, the first electronic device (e.g.,  1000 ) is configured to detect and respond to activation of the first input device (e.g.,  1004 , respond by performing the predefined operation or a second predefined operation), where the activation is different from and independent of the capture of biometric information. 
     In some embodiments, the application is configured to cause the first electronic device (e.g.,  1000 ) to capture the biometric information without detecting the activation of the first input device (e.g.,  1004 ). 
     While displaying the user interface (e.g.,  1006  of  FIG. 10A ) of the application for capturing biometric information from the biometric sensor (e.g.,  1004 ), the first electronic device (e.g.,  1000 ) detects ( 1104 ) a first activation of the first input device (e.g.,  1004 , a pressing of the first input device, such as a rotating crown, past a threshold amount to cause a “click” of the crown). 
     In response to detecting the first activation of the first input device (e.g.,  1004 , a press on the first input device) and while capturing biometric information from the biometric sensor (e.g.,  1004 ), in accordance with a determination that the first activation of the first input device (e.g.,  1004 ) was detected when first criteria are met (e.g., the device has captured less than a predetermined amount of biometric information and/or the first input device has been activated within at least a threshold amount of time, such as 5 seconds), where the first criteria are based on progress toward capturing biometric information with the biometric sensor (e.g.,  1004 ), the first electronic device (e.g.,  1000 ) performs ( 1106 ) a predefined operation associated with the first input device (e.g.,  1004 ) that interrupts capture of the biometric information (e.g., scrolling of a displayed content, exiting a currently active application, activation of a digital assistant function). Performing the predefined operation associated with the first input device (e.g.,  1004 ) that interrupts the capture of biometric information in accordance with the determination that the first activation of the first input device (e.g.,  1004 ) was detected when the first criteria are met provides the user with more control of the device by enabling the user to interrupt the capture of biometric information in certain situations through an input on the first input device. Providing additional control options without cluttering the UI with additional displayed controls enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     Also in response to detecting the first activation of the first input device (e.g.,  1004 , a press on the first input device) and while capturing biometric information from the biometric sensor (e.g.,  1004 ), in accordance with a determination that the first activation of the first input device (e.g.,  1004 ) was detected when the first criteria are not met, the first electronic device (e.g.,  1000 ) continues ( 1108 ) to capture the biometric information without performing the predefined operation associated with the first input device (e.g.,  1004 ). Continuing to capture the biometric information without performing the predefined operation associated with the first input device (e.g.,  1004 ) in accordance with the determination that the first activation of the first input device was detected when the first criteria are not met provides the user with more control of the device by enabling the user continue with the capturing of the biometric information in certain situations without having to manually re-initiate the recording process. Providing additional control options without cluttering the UI with additional displayed controls enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, prior to capturing the biometric information (e.g., while displaying an introductory animation, such as animation  808  of main user interface  806  as shown in  FIG. 8A ), the first electronic device (e.g.,  1000 ) detects a second activation of the first input device (e.g.,  1004 ). In some embodiments, in response to detecting the second activation of the first input device (e.g.,  1004 ), the first electronic device (e.g.,  1000 ) performs the predefined operation (e.g., performing the predefined operation without determining whether capture of biometric information is occurring). 
     In some embodiments, the predefined operation includes displaying, on the display (e.g.,  1002 ), a predefined user interface (e.g.,  1012 , a homescreen that includes one or more affordances for launching an application). In some embodiments, displaying the predefined user interface (e.g.,  1012 ) includes closing or suspending any currently active or running application (e.g., the application for capturing biometric information). 
     In some embodiments, the predefined operation includes displaying, on the display (e.g.,  1002 ), a user interface (e.g.,  1022 ) of a digital virtual assistant (e.g., by replacing display of the user interface (e.g.,  1006 ) of the application for capturing biometric information). 
     In some embodiments, the first criteria are met when capturing the biometric information has occurred for less than a first threshold amount of time (e.g., 5 seconds). 
     In some embodiments, after continuing to capture the biometric information without performing the predefined operation associated with the first input device (e.g.,  1004 ), the first electronic device (e.g.,  1000 ) detects ( 1110 ) a second activation of the first input device (e.g.,  1004 ). In some embodiments, in response to detecting the second activation of the first input device (e.g.,  1004 ), in accordance with a determination that the second activation of the first input device (e.g.,  1004 ) was detected within a predetermined time (e.g., 5 seconds) after detecting the first activation of the first input device (e.g.,  1004 ), the first electronic device (e.g.,  1000 ) performs ( 1112 ) the predefined operation associated with the first input device (e.g.,  1004 ) that interrupts capture of the biometric information. Performing the predefined operation associated with the first input device (e.g.,  1004 ) that interrupts the capture of the biometric information in accordance with the determination that the second activation of the first input device was detected within the predetermined time after detecting the first activation of the first input device provides the user with more control of the device and reduces the number of inputs needed to interrupt the capturing of the biometric information by allowing the user to quickly and easily interrupt the capturing of biometric information using the first input device. Providing additional control of the device and reducing the number of inputs needed to perform an operation enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, in response to detecting the second activation of the first input device (e.g.,  1004 ), in accordance with a determination that the second activation of the first input device (e.g.,  1004 ) was detected after the predetermined time after detecting the first activation of the first input device (e.g.,  1004 ), the first electronic device (e.g.,  1000 ) continues ( 1114 ) to capture the biometric information without performing the predefined operation associated with the first input device (e.g.,  1004 ). Continuing to capture the biometric information without performing the predefined operation associated with the first input device (e.g.,  1004 ) in accordance with the determination that the second activation of the first input device was detected after the predetermined time after detecting the first activation of the first input device provides the user with more control of the device by helping the user avoid unintentionally interrupting the capturing of the biometric information and simultaneously allowing the user to recognize that another and/or different input is required to interrupt the capturing of the biometric information. Providing additional control of the device (without cluttering the user interface with additional displayed controls) enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, upon (or prior to) capturing the biometric information (e.g., heart rhythm information, heart rate information) from the biometric sensor (e.g.,  1004 ), the first electronic device (e.g.,  1000 ) automatically disables a haptic feedback controller (e.g., a haptic actuator associated with the first input device) of the first electronic device (e.g.,  1000 ). In some embodiments, upon (or in response to) completing capturing the biometric information, the first electronic device (e.g.,  1000 ) automatically re-enables the haptic feedback controller. 
     In some embodiments, upon (or prior to) capturing the biometric information (e.g., heart rhythm information, heart rate information) from the biometric sensor, the first electronic device (e.g.,  1000 ) automatically disables a wireless communication radio (e.g., LTE connection) of the first electronic device (e.g.,  1000 ) and prevents a first type of notification (e.g.,  1026 , of a message, of an alert, a type of notification other than a timer notification) from being displayed, where the first type of notification includes a notification corresponding to an electronic communication (e.g., a text message, an email, a phone call) received while the capturing the biometric information. In some embodiments, the notifications that are prevented from being displayed do not include a timer notification. In some embodiments, upon (or in response to) completing capturing the biometric information, the first electronic device (e.g.,  1000 ) automatically re-enables the wireless communication radio and allows the first type of notification (e.g.,  1030 ) to be displayed. 
     Note that details of the processes described above with respect to method  1100  (e.g.,  FIG. 11 ) are also applicable in an analogous manner to the methods described above and below. For example, method  700  optionally includes one or more of the characteristics of the various methods described above with reference to method  1100 . For another example, method  900  optionally includes one or more of the characteristics of the various methods described above with reference to method  1100 . For example, method  1300  optionally includes one or more of the characteristics of the various methods described above with reference to method  1100 . For example, method  1500  optionally includes one or more of the characteristics of the various methods described above with reference to method  1100 . For brevity, these details are not repeated below. 
       FIGS. 12A-12S  illustrate exemplary user interfaces for managing aspects of health monitoring. The user interfaces in these figures are used to illustrate the processes described below, including the processes in  FIGS. 13A-13B . The exemplary user interfaces in these figures relate generally to monitoring health using recorded biometric information, and are not limited to a specific type of biometric information. Only for the sake of convenience, the exemplary user interfaces in these figures are described with reference to a type of biometric information—electrocardiogram (hereinafter “ECG”) information. 
       FIG. 12A  illustrates a first electronic device  1200  (e.g., corresponding to second electronic device  600 B, first electronic device  800 A, and/or first electronic device  1000 ). In some embodiments, first electronic device  1200  is a smartwatch. In some embodiments, first electronic device  1200  has a display  1202  and one or more input devices (e.g., including a touch layer of display  1202  and one or more mechanical buttons, such as a rotating crown). In some embodiments, first electronic device  1200  includes one or more biometric sensors (e.g., for recording ECG information, for detecting heart rhythm and heart rate of the user) comprising one or more electrodes integrated in an input device  1204  (e.g., a mechanical input device, such as a depressible, rotating crown) of first electronic device  1200 . In some embodiments, the one or more biometric sensors of first electronic device  1200  further comprise one or more electrodes of (e.g., integrated in) a housing portion (e.g., the backplate) of first electronic device  1200 , where the one or more electrodes integrated in the input device operate in conjunction with the one or more electrodes of the housing portion to capture biometric information (e.g., ECG information). Features concerning the one or more biometric sensors of first electronic device  1200  used to capture biometric information (e.g., ECG information) is described in greater detail in Appendix A. 
     In  FIG. 12A , first electronic device  1200  displays, on display  1202 , a summary page  1206  (e.g., corresponding to summary page  826  and summary page  1028 ) of an ECG application for a completed ECG recording, where the evaluation result of the completed ECG recording is a “regular rhythm” result, as indicated by indication  1208 A of summary region  1208 . In some embodiments, summary region  1208  also includes an indication  1208 B of a heart rate reading (e.g., in BPM) of the completed ECG recording. In some embodiments, while displaying summary page  1206 , the device displays (e.g., maintains display of) an animation (e.g., corresponding to animation  808  shown in  FIG. 8A , in its initial shape as shown in  FIG. 8A ) in the background of the summary page (e.g., in a lighter shade so that the summary page is easily legible to the user). 
     In some embodiments, summary region  1208  also includes a information affordance  1210  for viewing a detailed description about the respective evaluation result. In some embodiments, while displaying summary page  1206 , first electronic device  1200  detects (e.g., via a touch input) a user activation  1201  of information affordance  1210 . 
       FIG. 12B  illustrates first electronic device  1200  displaying, on display  1202 , at least a portion of a information page  1212  that includes description about medical characteristics of its respective result. In some embodiments, the description included in information page  1212  corresponds to the text description shown in possible results page  618  of the tutorial described with reference to  FIGS. 6A-6AE . In  FIG. 12B , first electronic device  1200  detects a scrolling input  1203  on input device  1204  (e.g., a rotating of input device  1204 , a rotating crown) in the direction of the bottom of the page. In some embodiments, the page can be scrolled via a scrolling touch gesture on the display. In response to detecting the scrolling input, first electronic device  1200  scrolls information page  1212  towards the bottom of the page. 
       FIG. 12C  illustrates first electronic device  1200  displaying, on display  1202 , the bottom portion of information page  1212  of the ECG application. In some embodiments, information page  1212  includes (e.g., at the end of the page), a return affordance  1214  for returning to the previous page of the ECG application. In some embodiments, while displaying information page  1212 , first electronic device  1200  detects (e.g., via a touch input) a user activation  1205  of return affordance  1214 . In response to detecting user activation  1205  of return affordance  1214 , first electronic device  1200  again displays, on display  1202  (e.g., replaces display of information page  1212  with), summary page  1206 , as shown in  FIG. 12D . 
     In  FIG. 12D , while displaying, on display  1202 , summary page  1206 , first electronic device  1200  detects a scrolling input  1207  on input device  1204  (e.g., a rotating of the input device, a rotating crown). In some embodiments, in response to detecting scrolling input  1207  on input device  1204 , first electronic device  1200  scrolls summary page  1206  to reveal additional items of the page, as shown in  FIG. 12E . 
     In some embodiments, as shown in  FIG. 12E , summary page  1206  includes a symptoms region  1216  that includes an affordance  1218  for associating (e.g., via user selection from a list of symptoms) one or more symptoms to the ECG recording represented by the summary page. In some embodiments, as also shown in  FIG. 12E , summary page  1206  includes an emergency contact affordance  1220  (e.g., for seeking immediate medical care, for contacting  911 ). In some embodiments, in response to detecting a user selection of emergency contact affordance  1220 , first electronic device  1200  initiates a phone call to an emergency contact (e.g.,  911 ). 
     In  FIG. 12E , while displaying symptoms region  1216  of summary page  1206 , first electronic device  1200  detects (e.g., via a touch input) a user activation  1209  of affordance  1218  for associating one or more symptoms to the ECG recording. In some embodiments, in response to detecting user activation  1209  of affordance  1218 , first electronic device  1200  displays, on display  1202  (e.g., replaces display of summary page  1206  with), a symptoms page  1222 , as shown in  FIG. 12F . 
     In some embodiments, symptoms page  1222  includes a selectable symptoms list  1224  that includes a plurality of symptoms options, of which one or more of the listed symptoms can be selected by the user from the list. In some examples, a symptom option of selectable symptoms list  1224  is a “Light headed or dizzy” option. In some examples, a symptom option of selectable symptoms list  1224  is a “Fainting or near fainting spells” option. In some examples, a symptom option of selectable symptoms list  1224  is a “Shortness of breath” option. In some examples, a symptom option of selectable symptoms list  1224  is a “Chest pain” option. In some examples, a symptom option of selectable symptoms list  1224  is an “Other” option (e.g., for indicating one or more symptoms that are not listed in the selectable symptoms list). In some examples, a symptom option of selectable symptoms list  1224  is a “None” option (e.g., for indicating that the user is not experiencing (or was not experiencing during the time of the ECG recording) any abnormal symptoms). 
     In  FIG. 12G , while displaying, on display  1202 , selectable symptoms list  1224  of symptoms page  1222 , first electronic device  1200  detects (e.g., via touch inputs) a user selection  1211  of a first symptom option  1224 A (e.g., a “Shortness of breath” option) and a user selection of  1213  of a second symptom option  1224 B (e.g., a “Chest pain” option). In response to detecting user selection  1211  of first symptom option  1224 A and user selection  1213  of second symptom option  1224 B, first electronic device  1200  displays, in selectable symptoms list  1224 , an indication  1226 A (e.g., a marking of the option, such as a checkmark) of first symptom option  1224 A and an indication  1226 B (e.g., a marking of the option, such as a checkmark) of second symptom option  1224 B, as shown in  FIG. 12H . In some embodiments, user-specified symptoms can be added (via symptoms page  1222 ) to evaluation results that correspond to “regular” results, as is the case in  FIGS. 12A-12H . 
     In some embodiments, first electronic device  1200  detects a scrolling gesture (e.g., via a scrolling touch gesture, via a rotating input on input device  1204 , a rotating crown) on symptoms page  1222  and, in response to the scrolling gesture, scrolls the page to reveal a bottom portion of the page. In some embodiments, as shown in  FIG. 12H , symptoms page  1222  includes (e.g., at the bottom of the page) a return affordance  1228  for confirming the selection of symptoms from selectable symptoms list  1224  to associate with the ECG recording and for returning to summary page  1206 . In  FIG. 12H , first electronic device  1200  detects (e.g., via a touch input) a user activation  1215  of return affordance  1228 . 
     In some embodiments, in response to detecting user activation  1215  of return affordance  1228 , if at least one of the user-specified symptoms are determined to be “serious” symptoms (e.g., symptoms that may require immediate medical attention), first electronic device  1200  displays, on the display  1202 , an alert page  1230 , as shown in  FIG. 12I . In some embodiments, alert page  1230  includes an emergency contact affordance  1232  which, when activated by the user, causes the device to initiate a process for seeking immediate medical attention (e.g., by initiating an emergency call to an emergency contact, by initiating a 911 call). In some embodiments, alert page  1230  includes a return affordance  1234  for returning to summary page  1206  (e.g., without contacting an emergency contact). 
     In some embodiments, in response to detecting user activation  1215  of return affordance  1228 , if none of the user-specified symptoms are determined to be “serious” symptoms (e.g., symptoms that may require immediate medical attention), first electronic device  1200  (automatically) displays summary page  1206  without displaying alert page  1230 . 
     In  FIG. 12I , while displaying, on display  1202 , alert page  1230 , first electronic device detects (e.g., via a touch input) a user activation  1217  of return affordance  1234  from alert page  1230 . In some embodiments, in response to detecting user activation  1217  of return affordance  1234 , first electronic device  1200  again displays, on display  1202  (e.g., replaces display of alert page  1230  with), an updated symptoms region  1236  (e.g., corresponding to previous symptoms region  1216 ) of summary page  1206 , as shown in  FIG. 12J , where updated symptoms region  1236  includes a list of the user-specified symptoms from selectable symptoms list  1224 . 
     In some embodiments, updated symptoms region  1236  further includes an edit affordance  1238  for returning to symptoms page  1222  to modify the user-specified symptoms from selectable symptoms list  1224 . In some embodiments, the user-specified symptoms of an ECG recording cannot be modified (either at first electronic device  1200  or at a second electronic device paired to first electronic device  1200 , such as a smartphone) upon leaving the ECG application while on that recording. 
     In  FIG. 12J , while displaying updated symptoms region  1236  in summary page  1206  (after having received user-specified symptoms for the recording), first electronic device  1200  detects a scrolling input  1219  on input device  1204  (e.g., a rotating of input device  1204 , a rotating crown) towards the bottom of summary page  1206 . In some embodiments, in response to detecting scrolling input  1219  on input device  1204 , first electronic device  1200  scrolls summary page towards the bottom of the page. 
       FIG. 12K  illustrates first electronic device  1200  displaying, on display  1202 , a bottom portion of summary page  1206 . In some embodiments, summary page  1206  includes an emergency contact affordance  1240  for initiating a process for seeking immediate medical attention (e.g., initiating an emergency call to an emergency contact, initiating a 911 call). In some embodiments, summary page  1206  includes a return affordance  1242  for confirming selections (e.g., user specified symptoms) made via summary page  1206  and for returning to a mina user interface  1244  of the ECG application (e.g., corresponding to user interface  644  described with reference to  FIGS. 6A-6AE , user interface  806  described with reference to  FIGS. 8A-8S , and user interface  1006  described with reference to  FIGS. 10A-10J ), as shown in  FIG. 12L . 
     In some embodiments, within a summary region (e.g.,  1248 ) of a summary page (e.g.,  1206 ), an indication of the evaluation result of an ECG recording (e.g., “regular,” “Atrial Fibrillation,” “high heart rate,” “low heart rate,” “inconclusive”) is highlighted with a warning visual characteristic (e.g., a warning color, such as yellow) if the result is an abnormal result (e.g., “Atrial Fibrillation,” “high heart rate,” “low heart rate”) different from a default visual characteristic (e.g., a default color). Similarly, in some embodiments, within a summary region of a summary page, an indication of the heart rate measurement of an ECG recording (e.g., the BPM) is highlighted with the warning visual characteristic (e.g., a warning color, such as yellow) if the heart rate is abnormal high (e.g., above 100 BPM) or abnormally low (e.g., below 50 BPM). In some embodiments, if one of the evaluation result or heart rate measurement is abnormal, both the indication of the evaluation result and the indication of the heart rate measurement are displayed with warning visual characteristic 
       FIG. 12M  illustrates a full expanded view of an example summary page  1246  corresponding to a first ECG recording performed using first electronic device  1200 . As indicated by a summary region  1248 , the first ECG recording has an Atrial Fibrillation result (an abnormal result), as shown by an evaluation result indication  1248 A (e.g., showing “Atrial Fibrillation”), with a normal heart rate (e.g., between 50-100 BPM), as shown by a BPM indication  1248 B (e.g., showing “80 BPM”). In some embodiments, evaluation result indication  1248 A is highlighted with the warning visual characteristic (e.g., text “Atrial Fibrillation” is displayed in a warning color, such as yellow, instead of a default color) and BPM indication  1248 B is not highlighted with the warning visual characteristic (e.g., text “80 BPM” is displayed in a default color, such as white). 
       FIG. 12N  illustrates a full expanded view of an example summary page  1250  corresponding to a second ECG recording performed using first electronic device  1200 . As indicated by a summary region  1252 , the second ECG recording has an Atrial Fibrillation result (an abnormal result), as shown by an evaluation result indication  1252 A (e.g., showing “Atrial Fibrillation”), with a high heart rate (e.g., over 100 BPM), as shown by a BPM indication  1252 B (e.g., showing “120 BPM”). In some embodiments, evaluation result indication  1252 A is highlighted with the warning visual characteristic (e.g., text “Atrial Fibrillation” is displayed in a warning color, such as yellow, instead of a default color) and BPM indication  1252 B is also highlighted with the warning visual characteristic (e.g., text “120 BPM” is displayed in the warning color, such as yellow). 
       FIG. 12O  illustrates a full expanded view of an example summary page  1254  corresponding to a third ECG recording performed using first electronic device  1200 . As indicated in summary page  1254 , the measured heart rate of the third ECG recording was too low (e.g., below 50 BPM) to check for Atrial Fibrillation. An evaluation result indication  1256 A (e.g., showing “Heart rate under 50”) of a summary region  1256  indicates a low heart rate result (an abnormal result) with a BPM indication  1256 B (e.g., showing “46 BPM”) of summary region  1256  showing the low heart rate. In some embodiments, evaluation result indication  1256 A is highlighted with the warning visual characteristic (e.g., text “Heart rate under 50” is displayed in a warning color, such as yellow) and BPM indication  1256 B is also highlighted with the warning visual characteristic (e.g., text “46 BPM” is displayed in the warning color, such as yellow). 
       FIG. 12P  illustrates a full expanded view of an example summary page  1258  corresponding to a fourth ECG recording performed using first electronic device  1200 . As indicated by a summary region  1260 , the fourth ECG recording has a regular rhythm result (a normal result, a non-Atrial Fibrillation result), as shown by an evaluation result indication  1260 A (e.g., showing “Regular Rhythm”), with a high heart rate (e.g., over 100 BPM), as shown by a BPM indication  1260 B (e.g., showing “120 BPM”). In some embodiments, evaluation result indication  1260 A is not highlighted with the warning visual characteristic (e.g., text “Regular Rhythm” is displayed in a default color, such as white) and BPM indication  1260 B is highlighted with the warning visual characteristic (e.g., text “120 BPM” is displayed in the warning color, such as yellow). 
     In some embodiments, as indicated by an alternate summary region  1261 , if the heart rhythm result is a normal result (e.g., a non-Atrial Fibrillation result) and the heart rate result is an abnormal result (e.g., a high or low heart rate result), evaluation result  1261 A of summary region  1261  indicates the abnormal heart rate result (e.g., by stating “Heart rate over 100,” “Heart rate over 150,” “Heart rate below 50”) while BPM indication  1261 B is maintained. In some embodiments, evaluation result indication  1261 A is highlighted with the warning visual characteristic (e.g., text “Heart rate over 100” is displayed in a warning color, such as yellow) and BPM indication  1261 B is highlighted with the warning visual characteristic (e.g., text “120 BPM” is displayed in the warning color, such as yellow). 
       FIG. 12Q  illustrates a full expanded view of an example summary page  1262  corresponding to a fifth ECG recording performed using first electronic device  1200 . As indicated in summary page  1262 , the measured heart rate of the fifth ECG recording was too high (e.g., over 150 BPM) to check for Atrial Fibrillation. An evaluation result indication  1264 A (e.g., showing “Heart rate over 150”) of a summary region  1264  indicates a high heart rate result (an abnormal result) with a BPM indication  1264 B (e.g., showing “152 BPM”) of summary region  1264  showing the high heart rate. In some embodiments, evaluation result indication  1264 A is highlighted with the warning visual characteristic (e.g., text “Heart rate over 150” is displayed in the warning color, such as yellow) and BPM indication  1264 B is also highlighted with the warning visual characteristic (e.g., text “152 BPM” is displayed in the warning color, such as yellow). 
       FIG. 12R  illustrates a full expanded view of an example summary page  1266  corresponding to a sixth ECG recording performed using first electronic device  1200 . As indicated by a summary region  1268 , the sixth ECG recording has a regular result (a normal result, a non-Atrial Fibrillation result), as shown by an evaluation result indication  1268 A (e.g., showing “Regular Rhythm”), with a normal heart rate (e.g., 50-100 BPM), as shown by a BPM indication  1268 B (e.g., showing “80 BPM”). In some embodiments, evaluation result indication  1268 A is not highlighted with the warning visual characteristic (e.g., text “Regular Rhythm” is displayed in the default color, such as white) and BPM indication  1268 B is also not highlighted with the warning visual characteristic (e.g., text “80 BPM” is displayed in the default color, such as white). 
       FIG. 12S  illustrates a full expanded view of an example summary page  1270  corresponding to a seventh ECG recording performed using first electronic device  1200 . As indicated by a summary region  1272 , the seventh ECG recording has an inconclusive result (e.g., due to a poor reading), as shown by an evaluation result indication  1272 A (e.g., showing “Inconclusive”), with an inconclusive heart rate, as shown by a BPM indication  1272 B. In some embodiments, evaluation result indication  1272 A is not highlighted with the warning visual characteristic (e.g., text “Inconclusive” is displayed in the default color, such as white) and BPM indication  1272 B is also not highlighted with the warning visual characteristic (e.g., text “− BPM” is displayed in the default color, such as white). In some embodiments, summary page  1270  of an inconclusive results includes a text description explaining to the user why the evaluation was inconclusive. 
       FIGS. 13A-13B  are a flow diagram illustrating a method for managing aspects of health monitoring, in accordance with some embodiments. Method  1300  is performed at a device (e.g.,  100 ,  300 ,  500 ,  600 B,  800 A,  1000 ,  1200 ) with a display and one or more input devices (e.g., a rotatable and depressible watch crown with integrated biometric sensors (e.g., comprising one or more electrodes) for detecting characteristics of the user&#39;s heart (e.g.,  1204 ), a touchscreen of the display, a mechanical button, a biometric sensor). Some operations in method  1300  are, optionally, combined, the orders of some operations are, optionally, changed, and some operations are, optionally, omitted. 
     As described below, method  1300  provides an intuitive way for managing health monitoring. The method reduces the cognitive burden on a user for managing health monitoring, thereby creating a more efficient human-machine interface. For battery-operated computing devices, enabling a user to manage health monitoring faster and more efficiently conserves power and increases the time between battery charges. 
     The first electronic device (e.g.,  1200 ) captures ( 1302 ) biometric information with a biometric sensor that is in communication with the first electronic device (e.g., comprising one or more electrodes integrated an input device (e.g.,  1204 ) operating in conjunction with one or more electrodes of a housing portion (e.g., backplate) of the first electronic device). 
     The first electronic device (e.g.,  1200 ) displays ( 1304 ), on the display (e.g.,  1202 ), a representation (e.g.,  1208 ) of an evaluation of a medical characteristic (e.g., related to heart health) determined based on the biometric information (e.g., ECG data, BPM data, heart-related data) captured by the biometric sensor. Displaying, on the display (e.g.,  1202 ), the representation of the evaluation of the medical characteristic improves visual feedback by enabling the user to quickly and easily see the result of the evaluation based on the captured biometric information. Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, upon (or prior to) capturing the biometric information with the biometric sensor, the first electronic device (e.g.,  1200 ) automatically disables a wireless communication radio (e.g., RF circuitry  108 , a LTE connection) of the first electronic device and prevents notifications (e.g., of a message, of an alert) from being displayed. Automatically disabling the wireless communication radio of the first electronic device (e.g.,  1200 ) and preventing notifications from being displayed enables the user to perform more accurate recordings of biometric information without manually disabling certain other functions of the device that may interrupt or interfere with the capturing of the biometric information. Performing an operation without requiring user input enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. In some embodiments, the notifications that are prevented from being displayed do not include a timer notification. 
     In some embodiments, upon (or in response to) completing capture of the biometric information, the first electronic device (e.g.,  1200 ) automatically re-enables the wireless communication radio (e.g., RF circuitry  108 , a LTE connection) and allows notifications to be displayed. Automatically re-enabling the wireless communication radio and allowing notifications to be displayed upon completing capture of the biometric information reduces the number of inputs required from the user to control the device by enabling the user to bypass having to manually re-enable the wireless communication radio and allow notifications to be displayed. Reducing the number of inputs needed to perform an operation enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the medical characteristic includes a heart rhythm characteristic (e.g., a characteristic corresponding to  1208 A) and a heart rate characteristic (e.g., a characteristic corresponding to  1208 B), and the displayed representation of the evaluation of the medical characteristic includes a heart rhythm evaluation (e.g., a electrocardiogram evaluation,  1208   a ) summary and a heart rate evaluation (e.g., a BPM reading,  1208 B) summary. 
     In some embodiments, the heart rhythm evaluation summary (e.g.,  1252 A) is displayed with a first visual characteristic (e.g., a first color, a warning color such as yellow) and the heart rate evaluation summary (e.g.,  1252 B) is displayed with the first visual characteristic when the heart rhythm evaluation corresponds to an abnormal result and the heart rate evaluation corresponds to an abnormal result. Displaying the heart rhythm evaluation summary (e.g.,  1252 A) with the first visual characteristic and the heart rate evaluation summary (e.g.,  1252 B) with the first visual characteristic when the heart rhythm evaluation corresponds to an abnormal result and the heart rate evaluation corresponds to an abnormal result improves visual feedback by enabling the user to quickly and easily recognize the out of the evaluation result and whether the evaluation result should be paid closer attention to (e.g., for further medical attention). Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. In some embodiments, the heart rhythm analysis evaluation (e.g.,  1252 A) corresponds to an abnormal result if an abnormal rhythm pattern is detected (e.g., signs of Atrial Fibrillation). In some embodiments, the heart rate evaluation (e.g.,  1252 B) corresponds to an abnormal result if the rate is greater than a high limit number (e.g., 100 BPM). 
     In some embodiments, the heart rhythm evaluation summary (e.g.,  1248 A) is displayed with the first visual characteristic and the heart rate evaluation summary (e.g.,  1248 B) is not displayed with the first visual characteristic when the heart rhythm evaluation corresponds to an abnormal result (e.g., signs of Atrial Fibrillation) and the heart rate evaluation corresponds to a normal result (e.g., 60-100 BPM). Displaying the heart rhythm evaluation summary (e.g.,  1248 A) with the first visual characteristic and not displaying the heart rate evaluation summary (e.g.,  1248 B) with the first visual characteristic when the heart rhythm evaluation corresponds to an abnormal result and the heart rate evaluation corresponds to a normal result improves visual feedback by enabling the user to quickly and easily recognize and differentiate between an abnormal result and a normal result, and whether an evaluation result should be paid closer attention to (e.g., for further medical attention). Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the heart rate evaluation summary (e.g.,  1260 A) is displayed with the first visual characteristic and the heart rhythm evaluation summary (e.g.,  1260 B) is not displayed with the first visual characteristic when the heart rate evaluation corresponds to an abnormal result (e.g., BPM below 50 or above 100) and the heart rhythm evaluation (e.g.,  1260 A) corresponds to a normal result. Displaying heart rate evaluation summary (e.g.,  1260 A) with the first visual characteristic and not displaying the heart rhythm evaluation summary (e.g.,  1260 B) with the first visual characteristic when the heart rate evaluation corresponds to an abnormal result (e.g., BPM below 50 or above 100) and the heart rhythm evaluation corresponds to a normal result improves visual feedback by enabling the user to quickly and easily recognize and differentiate between an abnormal result and a normal result, and whether an evaluation result should be paid closer attention to (e.g., for further medical attention). Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the heart rate evaluation summary (e.g.,  1264 A) is displayed with a first visual characteristic and the heart rhythm evaluation summary (e.g.,  1264 B) is displayed with the first visual characteristic when the heart rate evaluation corresponds to a highly abnormal result (e.g., BPM over 150 or below 50) such that a determination cannot be made on the heart rhythm evaluation. Displaying the heart rate evaluation summary (e.g.,  1264 A) and the heart rhythm evaluation summary (e.g.,  1264 B) with the first visual characteristic when the heart rate evaluation corresponds to a highly abnormal result (e.g., BPM over 150 or below 50) such that a determination cannot be made on the heart rhythm evaluation improves visual feedback by enabling the user to quickly and easily recognize that the result corresponds to a highly abnormal result and that the evaluation result should be paid closer attention to (e.g., for further medical attention). Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, in accordance with a determination that the evaluation of the medical characteristic cannot be determined (e.g., because the biometric information captured by the biometric sensor is incomplete or is of poor quality), the first electronic device (e.g.,  1200 ) displays ( 1306 ), in the representation of the evaluation, an indication that the evaluation was inconclusive (e.g.,  1272 A). In some embodiments, the evaluation also includes a text description (e.g.,  1270 ) explaining to the user why the evaluation was inconclusive (e.g., due to a poor reading from the biometric sensor). Providing the text description explaining to the user why the evaluation result was inconclusive improves visual feedback and provides the user with more control of the device by enabling the user to easily understand why the evaluation result and inconclusive (e.g., such that the user can take a new recording that addresses a reason for the inconclusive result). Improving visual feedback to the user and providing additional control of the device (without cluttering the user interface with additional displayed controls) enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     While displaying the representation (e.g.,  1208 ) of the evaluation of the medical characteristic, the first electronic device (e.g.,  1200 ) detects ( 1308 ), via the one or more input devices, a sequence of one or more inputs (e.g., a sequence of one or more touch inputs on a touchscreen of the display (e.g.,  1209 ,  1211 ,  1213 )) to add user-specified symptoms (e.g.,  1224 ) to the evaluation of the medical characteristic. In some embodiments, one or more symptoms are displayed in a list for user selection. Providing one or more symptoms as a list for user selection reduces the number of inputs required from the user to provide the one or more symptoms (e.g., allows the user to not have to type the one or more symptoms). Reducing the number of inputs needed to perform an operation enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. In some embodiments, the user selects one or more symptoms from the provided list of symptoms. 
     In some embodiments, while displaying, on the display (e.g.  1202 ), the representation (e.g.,  1208 ) of the evaluation of the medical characteristic (e.g., a result of the evaluation, data from the evaluation, such as BPM), the first electronic device (e.g.,  1200 ) detects, via a first input device (e.g.,  1204 ), a scrolling input (e.g.,  1207 ). In some embodiments, the first input device is a rotating crown (e.g.,  1204 ) and the scrolling input is a rotation of the rotating crown (e.g.,  1207 ). In some embodiments, the first input device is the touch layer of the display and the scrolling input is a scrolling touch gesture on the display (e.g.,  1202 ). Further in such embodiments, in response to detecting the scrolling input, the first electronic device (e.g.,  1200 ) scrolls a second user interface (e.g.,  1206 ) that includes the representation of the evaluation of the medical characteristic. Additionally in such embodiments, the first electronic device (e.g.,  1200 ) displays, on the display (e.g.,  1202 ), an add-symptoms affordance (e.g.,  1216 ) for adding the user-specified symptoms to the evaluation. Displaying, on the display (e.g.,  1202 ), the add-symptoms affordance for adding the user-specified symptoms to the evaluation provides visual feedback by allowing the user to quickly recognize how to add one or more symptoms to an evaluation result. Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the user-specified symptoms include a first symptom (e.g.,  1226 B) corresponding to a serious symptom (e.g., a symptom that may require immediate medical attention), and a first representation of the one or more representations of user-specified symptoms corresponding to the first symptom is displayed with a first visual characteristic (e.g., a warning color, such as yellow). In some embodiments, the user-specified symptoms include a second symptom (e.g.,  1226 A) corresponding to a non-serious symptom, and a second representation of the one or more representations of user-specified symptoms corresponding to the second symptom is displayed with a second visual characteristic (e.g., a non-warning color, a default color) that is different from the first visual characteristic. 
     In some embodiments, the evaluation of the medical characteristic is a normal result (no abnormalities detected, e.g., a normal result as discussed above with respect to method  700  and  FIG. 6H ) and the sequence of one or more inputs (e.g.,  1209 ,  1211 ,  1213 ) to add the user-specified symptoms is detected while displaying the representation of the evaluation corresponding to the normal result. Thus, in some embodiments, one or more symptoms can be added to an evaluation with no abnormal results. 
     In some embodiments, while displaying the representation (e.g.,  1208 ) of the evaluation of the medical characteristic, the first electronic device (e.g.,  1200 ) detects, via the one or more input devices (e.g.,  1202 ), a user activation of an information affordance (e.g.,  1210 ). In such embodiments, in response to detecting the user activation of the information affordance, the first electronic device (e.g.,  1200 ) displays, on the display (e.g.,  1202 ), text information (e.g.,  1212 ) related to the evaluation. Displaying, on the display (e.g.,  1202 ), the text information (e.g.,  1212 ) related to the evaluation in response to detecting the user activation of the information affordance provides more control of the device by enabling the user to easily access more information related to the evaluation result. Providing additional control options (without cluttering the user interface with additional displayed controls) enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. In some embodiments, the displayed text information related to the evaluation corresponds to the text information presented for the same type of evaluation during the onboarding process, as described in method  700  (e.g.,  FIGS. 6F-6L ). 
     In response to detecting the sequence of one or more inputs (e.g.,  1209 ,  1211 ,  1213 ), in accordance with a determination that at least one of the user-specified symptoms meet respective criteria, the first electronic device (e.g.,  1200 ) displays ( 1310 ), on the display (e.g.,  1202 ), a first user interface (e.g., a Symptom Alert user interface  1230 ) that includes an affordance (e.g.,  1232 ) that, when activated, initiates a process for seeking immediate medical attention (e.g., initiating an emergency call, initiating a 911 call). Displaying, on the display (e.g.,  1202 ), the first user interface (e.g.,  1230 ) that includes the affordance that, when activated, initiates the process for seeking immediate medical attention improves user control of the device by enabling the user to quickly and easily recognize that immediate medical attention may be necessary and enables the user to easily and conveniently initiate a process for seeking immediate medical attention. Providing additional control options and reducing the number of inputs needed to perform an operation enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In response to detecting the sequence of one or more inputs (e.g.,  1209 ,  1211 ,  1213 ), in accordance with a determination that (all of) the user-specified symptoms do not meet the respective criteria, the first electronic device (e.g.,  1200 ) displays ( 1312 ), on the display (e.g.,  1202 ), the representation of the evaluation of the medical characteristic and one or more representations of user-specified symptoms without displaying the first user interface (e.g., without displaying interface  1230 ). Displaying, on the display (e.g.,  1202 ), the representation of the evaluation of the medical characteristic and the one or more representations of the user-specified symptoms without displaying the first user interface (e.g.,  1230 ) improves visual feedback by enabling the user to easily view the evaluation and the user-specified symptoms upon user selection of the symptoms. Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, further in accordance with a determination that (all of) the user-specified symptoms do not meet the respective criteria, the first electronic device (e.g.,  1200 ) detects ( 1312 ), via the one or more input devices (e.g.,  1204 ), a scrolling gesture (e.g., a rotation of a rotating crow (e.g.,  1219 ), a scrolling input on the touch layer of the display). In some embodiments, in response to detecting, via the one or more input devices, the scrolling gesture, the first electronic device (e.g.,  1200 ) displays ( 1314 ), on the display (e.g.,  1202 ), an option for seeking medical attention (e.g., a selectable text allowing the user to initiate a process for contacting  911  (e.g.,  1240 )). Displaying, on the display (e.g.,  1202 ), the option for seeking medical attention in response to detecting the scrolling gesture improves user control of the device by providing the user with a quick and easy method for seeking medical attention, if the user determines that medical attention is needed. Providing additional control options (without cluttering the user interface with additional displayed controls) enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, subsequent to detecting the sequence of one or more inputs (e.g.,  1209 ,  1211 ,  1213 ), the first electronic device (e.g.,  1200 ) detects ( 1316 ) a user activation (e.g.,  1221 ) of a confirmation button (e.g.,  1242 ). In such embodiments, in response to (or subsequent to) detecting the user activation of the confirmation button, the first electronic device (e.g.,  1200 ) transmits ( 1318 ) (e.g., via a wireless communication radio of the device) the evaluation of the medical characteristic from the first electronic device (e.g.,  1200 ) to a second electronic device (e.g.,  100 ,  300 ,  500 ,  600 A), a smartphone that is paired with the first electronic device) for display of a corresponding representation of the evaluation of the medical characteristic on the second electronic device. 
     In some embodiments, the user-specified symptoms (e.g.,  1226 A,  1226 B) cannot be modified after detecting the user activation of the confirmation button.

       FIG. 14A  illustrates a first electronic device  1400 A (e.g., a smartphone similar to first electronic device  600 A) with a display  1402  and one or more input devices. In some embodiments, the one or more input devices include a touch layer of display  1402  for detecting touch input, one or more image sensors  1404  (e.g., a camera, a depth sensor), a first mechanical button  1406  configured to perform one or more operations (e.g., and including an integrated biometric sensor, such as a fingerprint sensor), and a second mechanical button  1408  configured to perform one or more operations. In some embodiments, first electronic device  1400 A includes a wireless communication radio (e.g., for LTE, Bluetooth, WiFi connections). In some embodiments, first electronic device  1400 A is paired with a second electronic device (e.g., a smartwatch). In some embodiments, the second electronic device corresponds to second electronic device  1400 B described below with reference to  FIGS. 14H-14J . In some embodiments, second electronic device  1400 B includes a plurality of biometric sensors, including a biometric sensor (comprising one or more photodiode sensors) enclosed in a housing of the second electronic device and an integrated biometric sensor (e.g., integrated with an input device, such as a rotatable input device, of the second electronic device). 
       FIG. 14A  illustrates first electronic device  1400 A displaying, on display  1402 , a first page  1410  of a setup process for performing initial setup of Atrial Fibrillation-detection management features (e.g., of an associated health application), where heart-related information (e.g., heart rhythm information) used to determine Atrial Fibrillation is captured using a second electronic device (e.g., second electronic device  1400 B) paired with first electronic device  1400 A. In some embodiments, first page  1410  of the setup process includes a graphical indication region  1410 A that graphically indicates (e.g., via a static image, via an animation) a function of the Atrial Fibrillation-detection management features (e.g., recording heart rhythm information). In some embodiments, first page  1410  of the setup process includes a text description region  1410 B describing background information relevant to the use of the Atrial Fibrillation-detection management features. 
     In some embodiments, first page  1410  of the setup process includes a date of birth entry field  1410 C for receiving a user input corresponding to the user&#39;s date of birth, where the user&#39;s date of birth is used to determine whether the user meets a minimum age requirement (e.g., 22 years of age) to use the Atrial Fibrillation-detection management features. In some embodiments, date of birth entry field  1410 C indicates (e.g., by stating “Required”) that the user&#39;s date of birth must be entered in order to proceed with the setup process. In some embodiments, date of birth entry field  1410 C includes scrollable month, day, and year fields. 
     In some embodiments, first page  1410  of the setup process does not include date of birth entry field  1410 C. In some embodiments, first page  1410  of the setup process includes (e.g., in addition to or alternatively to date of birth entry field  1410 C) an age restriction message (e.g., stating “You must be 22 years or older”) indicating to the user that the user must meet the minimum age requirement. 
     In some embodiments, first page  1410  of the setup process includes an affordance  1410 D for proceeding with the tutorial. In  FIG. 14A , while displaying first page  1410  of the Atrial Fibrillation-detection management setup process and after having received an input corresponding to the user&#39;s date of birth in entry field  1410 C, first electronic device  1400 A detects (e.g., via a touch input) a user activation  1401  of affordance  1410 D for proceeding with the setup process. 
     In some embodiments, in accordance with a determination that the minimum age requirement is not met (e.g., a determination made in response to detecting user activation  1401 ), first electronic device  1400 A displays, on display  1402 , an error notification (e.g., stating “The Atrial Fibrillation-detection management features are not intended for use by people under 22”) indicating that the user does not meet the requisite minimum age requirement. In some embodiments, the error notification is overlaid on first page  1410  of the setup process. In some embodiments, while displaying the error notification, the background of the display (displaying first page  1410 ) is dimmed (thereby emphasizing the displayed error notification). 
     In some embodiments, in response to detecting user activation  1401  (and in accordance with a determination that the minimum age requirement is met), first electronic device  1400 A displays, on display  1402  (e.g., replaces display of first page  1410  with), a second page  1412  of the setup process, as shown in  FIG. 14B . 
       FIG. 14B  illustrates first electronic device  1400 A displaying, on display  1402 , second page  1412  of the setup process for enabling Atrial Fibrillation-detection management features. In some embodiments, second page  1412  of the setup process includes an animation region  1412 A that graphically indicates (e.g., via a static image, via an animation) a feature of Atrial Fibrillation detection (e.g., that heart-related information can be captured at several different times during time period to determine whether Atrial Fibrillation exists). In some embodiments, second page  1412  of the setup process includes a text description region  1412 B that describes how the Atrial Fibrillation-detection features are implemented (using a second electronic device, such as second electronic device  1400 B). In some embodiments, second page  1412  of the setup process includes an affordance  1412 C for proceeding with the setup process. 
     In  FIG. 14B , while displaying second page  1412  of the Atrial Fibrillation-detection management setup process, first electronic device  1400 A detects (e.g., via a touch input) a user activation  1403  of affordance  1412 C for proceeding with the setup process. In some embodiments, in response to detecting user activation  1403 , first electronic device  1400 A displays, on display  1402  (e.g., replaces display of second page  1412  with), a third page  1414  of the setup process, as shown in  FIG. 14C . 
     In some embodiments, third page  1414  of the setup process indicates to the user (e.g., via a text description) one or more limitations of Atrial-Fibrillation evaluation results that are determined from heart-related information captured using the second electronic device (e.g., second electronic device  1400 B) (e.g., using a biometric sensor of the second electronic device comprising one or more photodiode sensors). In some examples, third page  1414  of the setup process includes a list  1414 A of one or more functional characteristics of the Atrial Fibrillation-detection features and/or medical characteristics that cannot be determined from the captured heart-related information (e.g., heart attack, blood clots/stroke). In some embodiments, third page  1414  of the setup process includes (e.g., at the bottom of the page), an affordance  1414 B for proceeding with the tutorial. 
     In  FIG. 14C , while displaying, on display  1402 , third page  1414  of the setup process, first electronic device  1400 A detects (e.g., via a touch input) a user activation  1405  of affordance  1414 B for proceeding with the setup process. In some embodiments, in response to detecting user activation  1405  of affordance  1414 B, the device displays, on display  1402 , a fourth page  1416  of the setup process, as shown in  FIG. 14D . 
       FIG. 14D  shows first electronic device  1400 A displaying, on display  1402 , fourth page  1416  of the setup process. In some embodiments, fourth page  1416  of the setup process includes a graphical indication region  1416 A and a text indication region  1416 B that provides instructions on how to view and manage Atrial Fibrillation-detection features when Atrial Fibrillation is determined based on heart-related information (e.g., captured at different times) captured using the second electronic device (e.g., second electronic device  1400 B). 
     In some embodiments, fourth page  1416  of the setup process includes a notification activation affordance  1416 C (e.g., showing “Turn on AFib Notifications”) for enabling notifications on first electronic device  1400 A and/or second electronic device  1400 B when Atrial Fibrillation is determined (using heart-related information captured using the second electronic device). In some embodiments, while displaying fourth page  1416  of the setup process, first electronic device  1400 A detects (e.g., via a touch input) a user activation  1407  of notification activation affordance  1416 C. In some embodiments, in response to detecting user activation  1407 , first electronic device  1400 A activates notifications to be displayed on first electronic device  1400 A and/or second electronic device  1400 B when Atrial Fibrillation is determined. 
       FIG. 14E  illustrates first electronic device  1400 A displaying, on display  1402 , a heart data user interface  1418  of a health application associated with the Atrial Fibrillation-detection features (e.g., operating after activation of notifications as described with respect to  FIGS. 14A-14D ). In some embodiments, the health application is accessible via a corresponding icon on a home user interface of the operating system of first electronic device  1400 A. 
     In some embodiments, heart data user interface  1418  of the health application includes a heart rate affordance  1420 . In some embodiments, heart rate affordance  1420  includes an indication of a range of the user&#39;s heart rate measured (e.g., via second electronic device  1400 B) during a certain period of time (e.g., today). In some embodiments, in response to detecting a user selection on heart rate affordance  1420 , heart data user interface  1418  displays a graphical depiction of the heart rate information summarized by heart rate affordance  1420  within a graphical depiction region  1422  of the user interface (and further highlights the affordance with a particular visual characteristic, such as a different color, to indicate to the user that the heart rate affordance is currently selected by the user). 
     In some embodiments, heart data user interface  1418  of the health application includes an Atrial Fibrillation affordance  1424 . In some embodiments, Atrial Fibrillation affordance  1424  includes an indication of the number of heart-related readings taken during a certain period of time (e.g., “Today (4 Readings)”) by the second electronic device (e.g., second electronic device  1400 B) (e.g., using a biometric sensor comprising one or more photodiode sensors of the second electronic device). In some embodiments, Atrial Fibrillation affordance  1424  includes an information affordance  1424 A for viewing and managing information about existing heart-related recordings taken by the second electronic device (e.g., using a biometric sensor comprising one or more photodiode sensors) to detect Atrial Fibrillation. 
     In  FIG. 14E , while displaying heart data user interface  1418  with Atrial Fibrillation affordance  1424  visible on display  1402 , first electronic device  1400 A detects (e.g., via a touch input) a user activation  1409  of information affordance  1424 A of Atrial Fibrillation affordance  1424 . In some embodiments, in response to detecting user activation  1409  of information affordance  1424 A, first electronic device  1400 A displays, on display  1402 , an Atrial Fibrillation management user interface  1426 , as shown in  FIG. 14F . 
       FIG. 14F  illustrates first electronic device  1400 A displaying, on display  1402 , an Atrial Fibrillation management user interface  1426 . In some embodiments, Atrial Fibrillation management user interface  1426  includes an alert log indication region  1426 A indicating Atrial Fibrillation alerts (if any) that have been generated upon detection of the condition using the second electronic device (e.g., second electronic device  1400 B). In some embodiments, if Atrial Fibrillation has not yet been detected (and thus no Atrial Fibrillation alerts have been generated), alert log indication region  1426 A indicates (e.g., by stating “No data”) that alerts have not yet been generated for Atrial Fibrillation detection. 
     In some embodiments, Atrial Fibrillation management user interface  1426  includes a recent analysis indication  1426 B indicating the time(s) of one or more most recent measurements of heart-related information made by the second electronic device (e.g., second electronic device  1400 B) (e.g., using a biometric sensor comprising one or more photodiode sensors of the second electronic device). In some embodiments, the one or more recent measurements shown in recent analysis indication  1426 B only include heart-related information captured after an Atrial Fibrillation alert has been presented (if any) by first electronic device  1400 A and/or second electronic device  1400 B. 
     In some embodiments, Atrial Fibrillation management user interface  1426  includes a show all affordance  1426 C for viewing a record of all past measurements of heart-related information using the second electronic device (e.g., second electronic device  1400 B) (e.g., using a biometric sensor comprising one or more photodiode sensors of the second electronic device). 
     In some embodiments, Atrial Fibrillation management user interface  1426  includes an indication  1426 D (e.g., a brief textual description) of how Atrial Fibrillation is detected by the second electronic device (e.g., second electronic device  1400 B). In some embodiments, Atrial Fibrillation management user interface  1426  includes a learn more affordance  1426 E for viewing additional information (e.g., expounding upon the description shown in indication  1426 D) about the Atrial Fibrillation-detection features. 
     In some embodiments, Atrial Fibrillation management user interface  1426  includes a disable notifications affordance  1426 F for disabling notifications from being presented (on first electronic device  1400 A and/or second electronic device  1400 B) when Atrial Fibrillation is detected. 
       FIG. 14G  illustrates first electronic device  1400 A displaying, on display  1402 , Atrial Fibrillation management user interface  1426  after two previous Atrial Fibrillation alerts have been presented at first electronic device  1400 A and/or second electronic device  1400 B, as indicated in alert log indication region  1426 A. In  FIG. 14G , alert log indication region  1426 A includes a first alert log  1428 A corresponding to a first Atrial Fibrillation alert (upon a first detection of Atrial Fibrillation) and a second alert log  1428 B corresponding to a second Atrial Fibrillation alert (upon a second detection of Atrial Fibrillation different from/separate from the first detection of Atrial Fibrillation). 
     In some embodiments, an alert log (e.g., first alert log  1428 A and second alert log  1428 B) includes a time at which the alert was generated. In some embodiments, in response to detecting a user activation of an alert log, first electronic device  1400 A displays, on display  1402 , a detailed alert log page that includes more detailed information about the captured heart-related information corresponding to the alert log (e.g., heart rate information, separate non-contiguous number of times during which the heart-related information was captured). 
       FIG. 14H  illustrates second electronic device  1400 B (e.g., paired with first electronic device  1400 A and including a biometric sensor comprising one or more photodiode sensors for detecting heart-related information) displaying, on a display  1430 , an Atrial Fibrillation notification  1432  corresponding to a received Atrial Fibrillation alert. In some embodiments, in response to detecting a user activation (e.g., via a touch input on display  1430  or via a scrolling gesture (e.g., a rotation of a rotating input device of second electronic device  1400 B or a scrolling input on display  1430  of second electronic device  1400 B)) of Atrial Fibrillation notification  1432 , second electronic device  1400 B displays, on display  1430 , an Atrial Fibrillation alert  1434 , as shown in  FIG. 14I . 
     In some embodiments, Atrial Fibrillation alert  1434  includes an indication  1434 A (e.g., a textual description) describing the reason for the alert (e.g., a detection of Atrial Fibrillation) and an explanation of the medical condition (e.g., Atrial Fibrillation) associated with the alert. In some embodiments, Atrial Fibrillation alert  1434  includes an indication  1434 B listing the one or more times (corresponding to measurements of heart-related information taken by second electronic device  1400 B (e.g., using a biometric sensor comprising one or more photodiode sensors)) during which Atrial Fibrillation was detected by the device. In some embodiments, indication  1434 B includes (not shown in  FIG. 14I ) one or more times and dates (e.g., within the previous 48 hours) during which Atrial Fibrillation was detected by the device. In some embodiments, Atrial Fibrillation alert  1434  includes an indication  1434 C indicating that medical attention may be required (e.g., stating “If you have not been diagnosed with Atrial Fibrillation by a physician, you should discuss with your doctor”). In some embodiments, Atrial Fibrillation alert  1434  includes an indication  1434 D warning that the user should not take a medical action (e.g., changing medication or treatments) without consulting a physician. 
     In some embodiments, Atrial Fibrillation alert  1434  includes an ECG affordance  1436  for taking more detailed heart-related information using an ECG application of second electronic device  1400 B (e.g., corresponding to the ECG application discussed above with respect to  FIGS. 6A-6AE, 8A-8S, 10A-10J, and 12A-12S ). In some embodiments, the more detailed heart-related information captured using the ECG application relates to the condition (e.g., Atrial Fibrillation) detected by second electronic device  1400 B without using the ECG application. In some embodiments, using the ECG application, the more detailed heart-related information is captured by one or more biometric sensors of second electronic device  1400 B that comprise one or more electrodes of (e.g., integrated in) an input device (e.g., a rotatable and depressible input device) of second electronic device  1400 B and one or more electrodes of (e.g., integrated in) a housing portion (e.g., the backplate) of second electronic device  1400 B, where the one or more electrodes integrated in the input device operate in conjunction with the one or more electrodes of the housing portion to capture the more detailed heart-related information (e.g., ECG information). Features concerning the one or more biometric sensors of second electronic device  1400 B used to capture the more detailed heart-related information (e.g., ECG information) is described in greater detail in Appendix A. In some embodiments, Atrial Fibrillation alert  1434  includes a dismiss affordance  1438  for dismissing the alert (e.g., without proceeding to the ECG application to record more detailed heart-related information). 
       FIG. 15  is a flow diagram illustrating a method for providing a health condition alert, in accordance with some embodiments. Method  1500  is performed at a device (e.g.,  100 ,  300 ,  500 ,  600 B,  800 A,  1000 ,  1200 ,  1400 B) with a display and one or more input devices (e.g., a rotatable and depressible input device with an integrated biometric sensor(s) (e.g., comprising one or more electrodes) for detecting characteristics of the user&#39;s heart (e.g.,  1204 ), a touch-sensitive surface, a mechanical button). The device is operably connected to a plurality of biometric sensors (e.g., a physical activity tracking sensor; a sensor integrated into electronic device; a plurality of sensors discrete from the electronic device that are connected (e.g., wireless connected) to the device). Some operations in method  1500  are, optionally, combined, the orders of some operations are, optionally, changed, and some operations are, optionally, omitted. 
     As described below, method  1500  provides an intuitive way for providing a health condition alert. The method reduces the cognitive burden on a user for managing a health condition, thereby creating a more efficient human-machine interface. For battery-operated computing devices, enabling a user to manage health monitoring faster and more efficiently conserves power and increases the time between battery charges. 
     The electronic device (e.g.,  1400 B) receives ( 1502 ) (e.g., via an internal connection from an integrated sensor of the electronic device (e.g.,  1400 ), via a wireless connection from a discrete sensor) first biometric information from a first biometric sensor of the plurality of biometric sensors. In some embodiments, the first biometric sensor comprises one or more photodiode sensors (e.g., enclosed in a housing of the electronic device). In some embodiments, the first biometric information comprises biometric information recorded at a first time and biometric information recorded at a second time different from (e.g., spaced apart from, non-contiguous with) the first time (e.g., a common time on a different day of the week). 
     In response to receiving the first biometric information and in accordance with a determination that the first biometric information satisfies first criteria (e.g., because the first biometric information includes heart rate or rhythm information that is abnormal and, optionally, because during a predetermined period of time (e.g., 48 hours), the electronic device (e.g.,  1400 B) has detected a threshold number of readings (e.g., five readings) having indications of irregular heart rate or rhythm), the electronic device (e.g.,  1400 B) displays ( 1504 ), on the display (e.g.,  1430 ), an alert (e.g.,  1434 ) including a first affordance (e.g.,  1436 ) for detecting additional biometric information (e.g., using an ECG application on the electronic device). Displaying an alert that includes a first affordance for detecting additional biometric information in response to receiving the first biometric information and in accordance with a determination that the first biometric information satisfies first criteria improves visual feedback by quickly (and in an easily-recognizable method) indicating to the user that an action (e.g., measuring additional biometric information) can be taken on the device. Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. In some embodiments, the biometric information relates to heart-related information. In some embodiments, the first criteria comprises abnormal heart rhythm information. 
     In some embodiments, the alert (e.g.,  1434 ) includes one or more times (e.g.,  1434 B) during which the first biometric information was recorded by the electronic device. In some embodiments, the alert includes an indication (e.g.,  1434 A, a text description) of a medical condition (e.g., abnormal heart rhythm, Atrial Fibrillation) identified based on the first biometric information. In some embodiments, the alert includes an indication (e.g.,  1434 C, a text description) to seek medical attention. Including an indication to seek medical attention enhances the operability of the device by quickly and efficiently indicating to the user an action relating to information provided by the device can be taken. Enhancing the operability of the device makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     The electronic device (e.g.,  1400 B) receives ( 1506 ), via the one or more input devices, user activation of the first affordance (e.g.,  1436 ). 
     Subsequent to receiving the user activation of the first affordance (e.g.,  1436 ), the electronic device (e.g.,  1400 B) receives ( 1512 ) (e.g., using the ECG application) second biometric information (e.g., more detailed heart rhythm information, ECG information) associated with the first biometric information from (at least) a second biometric sensor (e.g., a biometric sensor integrated with an input device (e.g.,  636 ,  804 ,  1004 ,  1204 , such as a rotatable input device) of the plurality of biometric sensors that is different from the first biometric sensor. In some embodiments, the second biometric sensor is integrated with a first input device (e.g.,  636 ,  804 ,  1004 ,  1204 , a rotatable and depressible input device) of the one or more input devices. In some embodiments, a first type of input on the first input device (e.g.,  629 ,  801 ,  1005 , such as a non-press input or a contact input, activates a feature(s) associated with activation of the second biometric sensor but does not activate a feature(s) associated with activation of the first input device. 
     In some embodiments, in response to receiving the user activation of the first affordance (e.g.,  1436 ) and prior to receiving the second biometric information, the electronic device (e.g.,  1400 B) displays ( 1508 ), on the display (e.g.,  1430 ), a first application (e.g.,  806 ,  1006 , an ECG application) associated with receiving the second biometric information. Displaying the first application associated with receiving the second biometric information in response to receiving the user activation of the first affordance and prior to receiving the second biometric information improves visual feedback by enabling the user to quickly and easily recognize that the second biometric information to be captured relates to features of the first application. Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, subsequent to displaying the first application (e.g.,  806 ,  1006 , an ECG application) and prior to receiving the second biometric information, the electronic device (e.g.,  1400 B) detects ( 1510 ) a user input (e.g.,  629 ,  801 ,  1005 , a non-press input, a contact input) on a first input device (e.g.,  636 ,  804 ,  1004 ,  1204 , a rotatable and depressible input device) of the one or more input devices, where the second biometric sensor is integrated with the first input device. In some embodiments, in response to detecting the user input, the electronic device receives the second biometric information from the second biometric sensor. 
     In some embodiments, the second biometric information is received from the second biometric sensor while the user input (e.g.,  629 ,  801 ,  1005 , a non-press input, a contact input) is maintained on the first input device (e.g.,  636 ,  804 ,  1004 ,  1204 , a rotatable and depressible input device). In some embodiments, in response to detecting that the user input is no longer maintained on the first input device, the electronic device (e.g.,  1400 B) ceases receiving the second biometric information from the second biometric sensor. In some embodiments, if the user input is restored within a predetermined period of time, the electronic device resumes receiving the second biometric information from the second biometric sensor. 
     Note that details of the processes described above with respect to method  1500  (e.g.,  FIG. 15 ) are also applicable in an analogous manner to the methods described above. For example, method  700  optionally includes one or more of the characteristics of the various methods described above with reference to method  1500 . For another example, method  900  optionally includes one or more of the characteristics of the various methods described above with reference to method  1500 . For another example, method  1100  optionally includes one or more of the characteristics of the various methods described above with reference to method  1500 . For another example, method  1300  optionally includes one or more of the characteristics of the various methods described above with reference to method  1500 . For brevity, these details are not repeated below. 
     The foregoing description, for purpose of explanation, has been described with reference to specific embodiments. However, the illustrative discussions above are not intended to be exhaustive or to limit the invention to the precise forms disclosed. Many modifications and variations are possible in view of the above teachings. The embodiments were chosen and described in order to best explain the principles of the techniques and their practical applications. Others skilled in the art are thereby enabled to best utilize the techniques and various embodiments with various modifications as are suited to the particular use contemplated. 
     Although the disclosure and examples have been fully described with reference to the accompanying drawings, it is to be noted that various changes and modifications will become apparent to those skilled in the art. Such changes and modifications are to be understood as being included within the scope of the disclosure and examples as defined by the claims. 
     As described above, one aspect of the present technology is the gathering and use of data available from various sources to improve the delivery to users of invitational content or any other content that may be of interest to them. The present disclosure contemplates that in some instances, this gathered data may include personal information data that uniquely identifies or can be used to contact or locate a specific person. Such personal information data can include demographic data, location-based data, telephone numbers, email addresses, home addresses, or any other identifying information. 
     The present disclosure recognizes that the use of such personal information data, in the present technology, can be used to the benefit of users. For example, the personal information data can be used to deliver targeted content that is of greater interest to the user. Accordingly, use of such personal information data enables calculated control of the delivered content. Further, other uses for personal information data that benefit the user are also contemplated by the present disclosure. 
     The present disclosure further contemplates that the entities responsible for the collection, analysis, disclosure, transfer, storage, or other use of such personal information data will comply with well-established privacy policies and/or privacy practices. In particular, such entities should implement and consistently use privacy policies and practices that are generally recognized as meeting or exceeding industry or governmental requirements for maintaining personal information data private and secure. For example, personal information from users should be collected for legitimate and reasonable uses of the entity and not shared or sold outside of those legitimate uses. Further, such collection should occur only after receiving the informed consent of the users. Additionally, such entities would take any needed steps for safeguarding and securing access to such personal information data and ensuring that others with access to the personal information data adhere to their privacy policies and procedures. Further, such entities can subject themselves to evaluation by third parties to certify their adherence to widely accepted privacy policies and practices. 
     Despite the foregoing, the present disclosure also contemplates embodiments in which users selectively block the use of, or access to, personal information data. That is, the present disclosure contemplates that hardware and/or software elements can be provided to prevent or block access to such personal information data. For example, in the case of advertisement delivery services, the present technology can be configured to allow users to select to “opt in” or “opt out” of participation in the collection of personal information data during registration for services. In another example, users can select not to provide location information for targeted content delivery services. In yet another example, users can select to not provide precise location information, but permit the transfer of location zone information. 
     Therefore, although the present disclosure broadly covers use of personal information data to implement one or more various disclosed embodiments, the present disclosure also contemplates that the various embodiments can also be implemented without the need for accessing such personal information data. That is, the various embodiments of the present technology are not rendered inoperable due to the lack of all or a portion of such personal information data. For example, content can be selected and delivered to users by inferring preferences based on non-personal information data or a bare minimum amount of personal information, such as the content being requested by the device associated with a user, other non-personal information available to the content delivery services, or publically available information.
