     FIELD 
     The present disclosure relates generally to computer user interfaces, and more specifically to techniques for managing and/or presenting health data. 
     BACKGROUND 
     Electronic devices include user interfaces that display various health information to a user. The health information can include data collected by sensors of the electronic devices and/or data input by the user. 
     BRIEF SUMMARY 
     Some techniques for managing and/or presenting health data 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 and/or presenting health data. Such methods and interfaces optionally complement or replace other methods for managing and/or presenting health data. 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 also provide a user with notifications related to health events, thereby providing the user with information related to his or her health without requiring input. Such methods and interfaces also enable a user to conveniently track health information, thereby facilitating a user&#39;s ability monitor his or her health.

     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 and/or presenting health data. For example, there is a need for electronic devices that monitor health data and notify a user of a potential health event without requiring periodic and/or intermittent user input over time. For another example, there is a need for electronic devices that facilitate a user&#39;s ability to log and/or track health information over time, such that a user can easily monitor his or her health. Such techniques can reduce the cognitive burden on a user who accesses health data on an electronic device, thereby enhancing productivity. Further, such techniques can reduce processor and battery power otherwise wasted on redundant user inputs. 
     Below,  FIGS. 1A-1B, 2, 3, 4A-4B, and 5A-5B  provide a description of exemplary devices for performing the techniques for managing event notifications.  FIGS. 6A-6P  illustrate exemplary user interfaces for generating a notification associated with a health event.  FIG. 7  is a flow diagram illustrating methods of generating a notification associated with a health event in accordance with some embodiments. The user interfaces in  FIGS. 6A-6P  are used to illustrate the processes described below, including the processes in  FIG. 7 .  FIGS. 8A-8U  illustrate exemplary user interfaces for managing health information over a predefined time range.  FIG. 9  is a flow diagram illustrating methods of managing health information over a predefined time range in accordance with some embodiments. The user interfaces in  FIGS. 8A-8U  are used to illustrate the processes described below, including the processes in  FIG. 9 . 
     In addition, in methods described herein where one or more steps are contingent upon one or more conditions having been met, it should be understood that the described method can be repeated in multiple repetitions so that over the course of the repetitions all of the conditions upon which steps in the method are contingent have been met in different repetitions of the method. For example, if a method requires performing a first step if a condition is satisfied, and a second step if the condition is not satisfied, then a person of ordinary skill would appreciate that the claimed steps are repeated until the condition has been both satisfied and not satisfied, in no particular order. Thus, a method described with one or more steps that are contingent upon one or more conditions having been met could be rewritten as a method that is repeated until each of the conditions described in the method has been met. This, however, is not required of system or computer readable medium claims where the system or computer readable medium contains instructions for performing the contingent operations based on the satisfaction of the corresponding one or more conditions and thus is capable of determining whether the contingency has or has not been satisfied without explicitly repeating steps of a method until all of the conditions upon which steps in the method are contingent have been met. A person having ordinary skill in the art would also understand that, similar to a method with contingent steps, a system or computer readable storage medium can repeat the steps of a method as many times as are needed to ensure that all of the contingent steps have been performed. 
     Although the following description uses terms “first,” “second,” etc. to describe various elements, these elements should not be limited by the terms. In some embodiments, these terms are 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. In some embodiments, the first touch and the second touch are two separate references to the same touch. In some 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 some embodiments, the electronic device is a computer system that is in communication (e.g., via wireless communication, via wired communication) with a display generation component. The display generation component is configured to provide visual output, such as display via a CRT display, display via an LED display, or display via image projection. In some embodiments, the display generation component is integrated with the computer system. In some embodiments, the display generation component is separate from the computer system. As used herein, “displaying” content includes causing to display the content (e.g., video data rendered or decoded by display controller  156 ) by transmitting, via a wired or wireless connection, data (e.g., image data or video data) to an integrated or external display generation component to visually produce the content. 
     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. 
     It should be appreciated that device  100  is only one example of a portable multifunction device, and that device  100  optionally has more or fewer components than shown, optionally combines two or more components, or optionally has a different configuration or arrangement of the components. The various components shown in  FIG. 1A  are implemented in hardware, software, or a combination of both hardware and software, including one or more signal processing and/or application-specific integrated circuits. 
     Memory  102  optionally includes high-speed random access memory and optionally also includes non-volatile memory, such as one or more magnetic disk storage devices, flash memory devices, or other non-volatile solid-state memory devices. Memory controller  122  optionally controls access to memory  102  by other components of device  100 . 
     Peripherals interface  118  can be used to couple input and output peripherals of the device to CPU  120  and memory  102 . The one or more processors  120  run or execute various software programs (such as computer programs (e.g., including instructions)) and/or sets of instructions stored in memory  102  to perform various functions for device  100  and to process data. In some embodiments, peripherals interface  118 , CPU  120 , and memory controller  122  are, optionally, implemented on a single chip, such as chip  104 . In some other embodiments, they are, optionally, implemented on separate chips. 
     RF (radio frequency) circuitry  108  receives and sends RF signals, also called electromagnetic signals. RF circuitry  108  converts electrical signals to/from electromagnetic signals and communicates with communications networks and other communications devices via the electromagnetic signals. RF circuitry  108  optionally includes well-known circuitry for performing these functions, including but not limited to an antenna system, an RF transceiver, one or more amplifiers, a tuner, one or more oscillators, a digital signal processor, a CODEC chipset, a subscriber identity module (SIM) card, memory, and so forth. RF circuitry  108  optionally communicates with networks, such as the Internet, also referred to as the World Wide Web (WWW), an intranet and/or a wireless network, such as a cellular telephone network, a wireless local area network (LAN) and/or a metropolitan area network (MAN), and other devices by wireless communication. The RF circuitry  108  optionally includes well-known circuitry for detecting near field communication (NFC) fields, such as by a short-range communication radio. The wireless communication optionally uses any of a plurality of communications standards, protocols, and technologies, including but not limited to Global System for Mobile Communications (GSM), Enhanced Data GSM Environment (EDGE), high-speed downlink packet access (HSDPA), high-speed uplink packet access (HSUPA), Evolution, Data-Only (EV-DO), HSPA, HSPA+, Dual-Cell HSPA (DC-HSPDA), long term evolution (LTE), near field communication (NFC), wideband code division multiple access (W-CDMA), code division multiple access (CDMA), time division multiple access (TDMA), Bluetooth, Bluetooth Low Energy (BTLE), Wireless Fidelity (Wi-Fi) (e.g., IEEE 802.11a, IEEE 802.11b, IEEE 802.11g, IEEE 802.11n, and/or IEEE 802.11ac), voice over Internet Protocol (VoIP), Wi-MAX, a protocol for e-mail (e.g., Internet message access protocol (IMAP) and/or post office protocol (POP)), instant messaging (e.g., extensible messaging and presence protocol (XMPP), Session Initiation Protocol for Instant Messaging and Presence Leveraging Extensions (SIMPLE), Instant Messaging and Presence Service (IMPS)), and/or Short Message Service (SMS), or any other suitable communication protocol, including communication protocols not yet developed as of the filing date of this document. 
     Audio circuitry  110 , speaker  111 , and microphone  113  provide an audio interface between a user and device  100 . Audio circuitry  110  receives audio data from peripherals interface  118 , converts the audio data to an electrical signal, and transmits the electrical signal to speaker  111 . Speaker  111  converts the electrical signal to human-audible sound waves. Audio circuitry  110  also receives electrical signals converted by microphone  113  from sound waves. Audio circuitry  110  converts the electrical signal to audio data and transmits the audio data to peripherals interface  118  for processing. Audio data is, optionally, retrieved from and/or transmitted to memory  102  and/or RF circuitry  108  by peripherals interface  118 . In some embodiments, audio circuitry  110  also includes a headset jack (e.g.,  212 ,  FIG. 2 ). The headset jack provides an interface between audio circuitry  110  and removable audio input/output peripherals, such as output-only headphones or a headset with both output (e.g., a headphone for one or both ears) and input (e.g., a microphone). 
     I/O subsystem  106  couples input/output peripherals on device  100 , such as touch screen  112  and other input control devices  116 , to peripherals interface  118 . I/O subsystem  106  optionally includes display controller  156 , optical sensor controller  158 , depth camera controller  169 , intensity sensor controller  159 , haptic feedback controller  161 , and one or more input controllers  160  for other input or control devices. The one or more input controllers  160  receive/send electrical signals from/to other input control devices  116 . The other input control devices  116  optionally include physical buttons (e.g., push buttons, rocker buttons, etc.), dials, slider switches, joysticks, click wheels, and so forth. In some embodiments, input controller(s)  160  are, optionally, coupled to any (or none) of the following: a keyboard, an infrared port, a USB port, and a pointer device such as a mouse. The one or more buttons (e.g.,  208 ,  FIG. 2 ) optionally include an up/down button for volume control of speaker  111  and/or microphone  113 . The one or more buttons optionally include a push button (e.g.,  206 ,  FIG. 2 ). In some embodiments, the electronic device is a computer system that is in communication (e.g., via wireless communication, via wired communication) with one or more input devices. In some embodiments, the one or more input devices include a touch-sensitive surface (e.g., a trackpad, as part of a touch-sensitive display). In some embodiments, the one or more input devices include one or more camera sensors (e.g., one or more optical sensors  164  and/or one or more depth camera sensors  175 ), such as for tracking a user&#39;s gestures (e.g., hand gestures and/or air gestures) as input. In some embodiments, the one or more input devices are integrated with the computer system. In some embodiments, the one or more input devices are separate from the computer system. In some embodiments, an air gesture is a gesture that is detected without the user touching an input element that is part of the device (or independently of an input element that is part of the device) and is based on detected motion of a portion of the user&#39;s body through the air including motion of the user&#39;s body relative to an absolute reference (e.g., an angle of the user&#39;s arm relative to the ground or a distance of the user&#39;s hand relative to the ground), relative to another portion of the user&#39;s body (e.g., movement of a hand of the user relative to a shoulder of the user, movement of one hand of the user relative to another hand of the user, and/or movement of a finger of the user relative to another finger or portion of a hand of the user), and/or absolute motion of a portion of the user&#39;s body (e.g., a tap gesture that includes movement of a hand in a predetermined pose by a predetermined amount and/or speed, or a shake gesture that includes a predetermined speed or amount of rotation of a portion of the user&#39;s body). 
     A quick press of the push button optionally disengages a lock of touch screen  112  or optionally begins a process that uses gestures on the touch screen to unlock the device, as described in U.S. patent application Ser. No. 11/322,549, “Unlocking a Device by Performing Gestures on an Unlock Image,” filed Dec. 23, 2005, U.S. Pat. No. 7,657,849, which is hereby incorporated by reference in its entirety. A longer press of the push button (e.g.,  206 ) optionally turns power to device  100  on or off. The functionality of one or more of the buttons are, optionally, user-customizable. Touch screen  112  is used to implement virtual or soft buttons and one or more soft keyboards. 
     Touch-sensitive display  112  provides an input interface and an output interface between the device and a user. Display controller  156  receives and/or sends electrical signals from/to touch screen  112 . Touch screen  112  displays visual output to the user. The visual output optionally includes graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). 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. 
     Touch screen  112  optionally uses LCD (liquid crystal display) technology, LPD (light emitting polymer display) technology, or LED (light emitting diode) technology, although other display technologies are used in other embodiments. Touch screen  112  and display controller  156  optionally detect contact and any movement or breaking thereof using any of a plurality of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with touch screen  112 . In an exemplary embodiment, projected mutual capacitance sensing technology is used, such as that found in the iPhone® and iPod Touch® from Apple Inc. of Cupertino, Calif. 
     A touch-sensitive display in some embodiments of touch screen  112  is, optionally, analogous to the multi-touch sensitive touchpads described in the following U.S. Pat. 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. 11/038,590, “Mode-Based Graphical User Interfaces For Touch Sensitive Input Devices,” filed Jan. 18, 2005; (6) 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 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.

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. 
     Device  100  optionally also includes one or more optical sensors  164 .  FIG. 1A  shows an optical sensor coupled to optical sensor controller  158  in I/O subsystem  106 . Optical sensor  164  optionally includes charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensor  164  receives light from the environment, projected through one or more lenses, and converts the light to data representing an image. In conjunction with imaging module  143  (also called a camera module), optical sensor  164  optionally captures still images or video. 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 depth camera sensors  175 .  FIG. 1A  shows a depth camera sensor coupled to depth camera controller  169  in I/O subsystem  106 .

In some embodiments, in conjunction with imaging module  143  (also called a camera module), depth camera sensor  175  is optionally used to determine a depth map of different portions of an image captured by the imaging module  143 . In some embodiments, a depth camera sensor is located on the front of device  100  so that the user&#39;s image with depth information is, optionally, obtained for video conferencing while the user views the other video conference participants on the touch screen display and to capture selfies with depth map data. In some embodiments, the depth camera sensor  175  is located on the back of device, or on the back and the front of the device  100 . In some embodiments, the position of depth camera sensor  175  can be changed by the user (e.g., by rotating the lens and the sensor in the device housing) so that a depth camera sensor  175  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).

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.

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 .

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 and a GPS (or GLONASS or other global navigation system) receiver 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:

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 (such as computer programs (e.g., including instructions)), 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 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 computer programs (e.g., sets of instructions or including instructions) need not be implemented as separate software programs (such as computer programs (e.g., including instructions)), 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, 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  and  900  ( FIGS. 7 and 9 ). 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. 
     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). 
     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. 
     Attention is now directed towards embodiments of user interfaces (“UI”) and associated processes that are implemented on an electronic device, such as portable multifunction device  100 , device  300 , or device  500 . 
       FIGS. 6A-6P  illustrate exemplary user interfaces for generating notifications associated with a health event, in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in  FIG. 7 . 
       FIG. 6A  illustrates computer system  600  having display generation component  602  and displaying, via display generation component  602 , health user interface  604  of a health application of computer system  600  on a first date (e.g., Sunday, April 5th). At  FIG. 6A , health user interface  604  includes health data user interface objects  604   a  and  604   b  and health event notification user interface object  606 . Health data user interface objects  604   a  and  604   b  include information related to health parameters (e.g., quantitative and/or qualitative measurements and/or characteristics detected by a sensor of computer system  600  and/or received by computer system  600  via user input and/or from an external device) of a user associated with computer system  600 . In some embodiments, health user interface  604  is a home screen or a default screen of the health application that computer system  600  displays, via display generation component  602 , upon launching the health application. 
     At  FIG. 6A , computer system  600  displays health event notification user interface object  606  prompting a user to enable and/or activate notifications related to a particular health event. Health event notification user interface object  606  is associated with hypertension notifications that computer system  600  generates in response to a determination that a user associated with computer system  600  is at risk for hypertension. As used herein, “hypertension” refers to a user having and/or being at risk of chronic high blood pressure, as opposed to a single instance and/or single measurement of high blood pressure. Therefore, computer system  600  generates hypertension notifications upon determining that a user associated with computer system  600  has regular occurrences of high blood pressure (e.g., instead of the user simply having one instance and/or one measurement indicative of high blood pressure). 
     Computer system  600  displays health event notification user interface object  606  on health user interface  604  based on a determination that the user has not previously enabled and/or activated hypertension notifications. In some embodiments, health event notification user interface object  606  can be displayed on another user interface of the health application, such as a checklist user interface that prompts a user to enable and/or activate tracking of health parameters (e.g., heart rate and/or rhythm monitoring, electrocardiogram monitoring, blood oxygen monitoring, noise exposure monitoring, and/or cardio fitness level monitoring) that have not yet been enabled and/or activated by the user. In some embodiments, computer system  600  enables and/or activates hypertension notifications by default and/or without user input (e.g., computer system  600  enables hypertension notifications as a default setting upon initial start-up of computer system  600 ). 
     At  FIG. 6A , computer system  600  detects user input  650   a  (e.g., a tap gesture) corresponding to selection of user interface object  606   a  (e.g., user interface object labeled “Enable”) of health event notification user interface object  606 . In response to detecting user input  650   a , computer system  600  displays first set-up user interface  608  on the first date, as shown at  FIG. 6B . First set-up user interface  608  includes additional information related to enabling and/or activating hypertension notifications. For instance, first set-up user interface  608  includes learn more region  608   a  that provides information related to hypertension and/or the hypertension notifications. As such, the user associated with computer system  600  can obtain further guidance from learn more region  608   a  before deciding to enable and/or activate the hypertension notifications. At  FIG. 6B , computer system  600  detects user input  650   b  (e.g., a tap gesture) on user interface object  608   b  (e.g., user interface object labeled “Set Up”). In response to detecting user input  650   b , computer system  600  displays second set-up user interface  610  on the first date, as shown at  FIG. 6C . 
     Second set-up user interface  610  includes further information (e.g., textual information) regarding the hypertension notifications that computer system  600  generates. At  FIG. 6C , computer system  600  detects user input  650   c  (e.g., a tap gesture) on user interface object  610   a  (e.g., user interface object labeled “Enable”) of second set-up user interface  610 . In response to detecting user input  650   c , computer system  600  displays third set-up user interface  612  on the first date, as shown at  FIG. 6D . 
     Third set-up user interface  612  includes birth date user interface object  612   a , first diagnosis user interface object  612   b , second diagnosis user interface object  612   c , and next user interface object  612   d . In some embodiments, computer system  600  is configured to enable and/or activate the hypertension notifications for users that satisfy feature-eligibility criteria and to not enable and/or activate (e.g., block enabling and/or activation of) the hypertension notifications for user that do not satisfy the feature-eligibility criteria. For example, the feature-eligibility criteria includes a criterion that the user is above a threshold age (e.g., 22 years old). Accordingly, computer system  600  receives information related to a birth date of the user associated with computer system  600 . In some embodiments, computer system  600  displays (e.g., pre-populates) a birth date in birth date user interface object  612   a  corresponding to a birth date previously received by computer system  600  (e.g., input by the user and/or received by computer system  600  during an initial set up and/or activation of computer system  600 ). In some embodiments, computer system  600  receives the birth date and displays the received birth date in birth date user interface object  612   a  in response to one or more inputs corresponding to selection of birth date user interface object  612   a.    
     In addition, the feature-eligibility criteria includes a criterion that the user has not been diagnosed with hypertension (e.g., received a diagnosis from a physician). At  FIG. 6D , third set-up user interface  612  includes first diagnosis user interface object  612   b  corresponding to the user having been previously diagnosed with hypertension (e.g., the user obtained a hypertension diagnosis from a physician). Second diagnosis user interface object  612   c  corresponds to the user not having been previously diagnosed with hypertension (e.g., the user has not obtained a hypertension diagnosis from a physician). In some embodiments, computer system  600  is configured to enable and/or activate the hypertension notifications for users that have not received a hypertension diagnosis and configured to not enable and/or activate (e.g., block enabling and/or activation of) hypertension notifications for users that have received a hypertension diagnosis. In some embodiments, computer system  600  is configured to not enable and to not collect and store sensor data for the purposes of determining whether to provide hypertension notifications for users that do not meet the feature-eligibility criteria. In some embodiments, computer system  600  does not make determinations based on hypertension notification criteria for users that do not meet the feature-eligibility criteria. 
     In some embodiments, next user interface object  612   d  is not available for selection (e.g., via user input) in response to the birth date being associated with an age below the threshold age and/or in response to user input selecting first diagnosis user interface object  612   b  (e.g., next user interface object  612   d  is greyed out or not displayed). In other words, computer system  600  does not enable the user to complete the set-up (e.g., enabling and/or activation) of hypertension notifications if the user is below the threshold age and/or the user has previously been diagnosed with hypertension. In some embodiments, computer system  600  forgoes display of health event notification user interface object  606  on health user interface  604  in response to detecting that an age of the user is below the threshold age and/or in response to receiving data indicative of a hypertension diagnosis of the user associated with computer system  600 . 
     At  FIG. 6D , computer system  600  receives and/or detects a birth date of the user that is associated with an age above the threshold age and receives user input corresponding to selection of second diagnosis user interface object  612   c . As such, next user interface object  612   d  is available for selection. At  FIG. 6D , computer system  600  detects user input  650   d  on next user interface object  612   d . In response to detecting user input  650   d , computer system  600  displays fourth set-up user interface  614  on the first date, as shown at  FIG. 6E . 
     At  FIG. 6E , fourth set-up user interface  614  includes first informational platter  614   a , second informational platter  614   b , and third informational platter  614   c . Informational platters  614   a ,  614   b , and  614   c  provided additional details regarding the hypertension notifications. The additional details may include textual information that provides guidance and/or suggested actions for the user upon receipt and/or absence of a hypertension notification. At  FIG. 6E , computer system  600  detects user input  650   e  on user interface object  614   d  of fourth set-up user interface  614 . In response to detecting user input  650   e , computer system  600  displays confirmation user interface  616  on the first date, as shown at  FIG. 6F . 
     At  FIG. 6F , confirmation user interface  616  includes hypertension notifications user interface object  616   a  (e.g., a toggle). Hypertension notifications user interface object  616   a  is in an active and/or “on” position, thereby indicating that computer system  600  successfully enabled and/or activated the hypertension notifications. Confirmation user interface  616  verifies to the user that the set-up process for enabling the hypertension notifications is successfully completed. In some embodiments, computer system  600  detects user input (e.g., a tap gesture; not shown) on done user interface object  616   b . In response to detecting user input on done user interface object  616   b , computer system  600  displays health user interface  604  (e.g., health user interface  604  without health event notification user interface object  606 ) and/or hypertension user interface  644  (e.g., hypertension user interface  644  without notification user interface objects  646   a  and  646   b ), as described in below with reference to  FIG. 6L . 
     After computer system  600  enables and/or activates the hypertension notifications, computer system  600  initiates a process for one or more sensors  618 ,  620 , and/or  622  of computer system  624  to collect data corresponding to one or more parameters and/or characteristics of user of computer system  624 . As set forth below, computer system  624  is in communication with computer system  600  and provides (e.g., transmits) collected data and/or an indication that a set of notification criteria (e.g., hypertension notification criteria) has been satisfied to computer system  600  (e.g., via a wireless signal, such as Bluetooth, Wi-Fi, and/or Zigbee). 
     At  FIG. 6G , computer system  624  collects data from sensors  618 ,  620 , and/or  622  over a predetermined period of time, such as 30 days, before computer system  624  and/or computer system  600  determines whether the data satisfies the set of notification criteria (e.g., hypertension notification criteria). For instance,  FIG. 6G  includes table  626  to illustrate days and/or times at which data is collected from sensors  618 ,  620 , and/or  622  after computer system  600  enables and/or activates the hypertension notifications. Table  626  includes first day  626   a , second day  626   b , and third day  626   c  that each fall within the predetermined period of time (e.g., 30 days from the first date of Sunday, April 5th). As shown at  FIG. 6G , data is collected on each of first day  626   a , second day  626   b , and third day  626   c  as represented by check marks in the “Data Collected” column of table  626 . While  FIG. 6G  illustrates that data is collected on first day  626   a , second day  626   b , and third day  626   c  within the predetermined period of time, data is also collected at other times (e.g., other days and/or multiple times within first day  626   a , second day  626   b , and/or third day  626   c ) within the predetermined period of time. In some embodiments, data is collected on days that the user wears computer system  624  (e.g., on a wrist of user) for an amount of time that is sufficient for sensors  618 ,  620 , and/or  622  to collect at least one measurement. In some embodiments, computer system  600  and/or computer system  624  determine whether the data satisfies the set of notification criteria (e.g., hypertension notification criteria) in response to the data including a threshold number of data points. For example, computer system  600  and/or computer system  624  determines whether the data includes data points collected on at least 15 days of the 30 day period of time and/or that the data includes data points for at least 5 hours, 8 hours, 10 hours, and/or 12 hours for each of the 15 days within the 30 day time period before making the determination as to whether or not the data satisfies the notification criteria. In some embodiments, computer system  600  and/or computer system  624  does not determine whether the data satisfies the set of notification criteria (e.g., hypertension notification criteria) if the data does not include the threshold number of data points. As such, computer system  600  and/or computer system  624  does not generate a hypertension notification unless the data includes a threshold number of data points. 
     The predetermined period of time is sufficiently long so that computer system  624  collects enough data to determine whether the user is at risk for hypertension. Therefore, the predetermined period of time is greater than 1 hour, 1 day, and/or 1 week. Further, the data collected over the predetermined period of time includes individual data points that are spaced apart from one another by an amount of time that is greater than an amount of time for collecting a respective data point. For example, the data collected over the period of time can include a first data point collected on a first day of the predetermined period of time and a second data point collected on a second day of the predetermined period of time, where the first day and the second day are spaced apart by multiple days. In addition, sensors  618 ,  620 , and/or  622  can collect individual data points in less than 1 second, 1 second, and/or 1 minute. Thus, the time computer system  624  spends collecting individual data points is substantially less than the predetermined period of time over which data is ultimately collected in order to determine whether the data satisfies the set notification criteria. 
     As set forth above, computer system  600  and/or computer system  624  determines whether the data collected over the predetermined period of time satisfies the set of notification criteria after the predetermined period of time has elapsed. In some embodiments, the set of notification criteria includes a threshold risk score (e.g., a quantitative value). Computer system  600  and/or computer system  624  determines a risk score by inputting the data collected over the predetermined period of time into an algorithm (e.g., a machine learning algorithm). The algorithm is configured to assess the data collected over the predetermined period of time for trends and/or patterns associated with hypertension. For instance, the algorithm is generated based on clinical data from users other than the current user associated with computer system  600  and computer system  624 . The clinical data includes data from users diagnosed with hypertension, and optionally, data from users that have normal blood pressure and have not been diagnosed with hypertension. Accordingly, the algorithm analyzes the data in order to generate a risk score (e.g., a quantitative value) associated with whether the user associated with computer system  600  and computer system  624  has hypertension. In response to the algorithm generating a risk score that meets or exceeds the threshold risk score, computer system  600  and/or computer system  624  determines that the data collected over the predetermined period of time satisfies the set of notification criteria. In contrast, in response to the algorithm generating a risk score that is below the threshold risk score, computer system  600  and/or computer system  624  determines that the data collected over the predetermined period of time does not satisfy the set of notification criteria. 
     At  FIG. 6G , sensor  618  is a photoplethysmogram sensor (e.g., a photoplethysmograph) that collects data indicative of changes in light absorption of the skin. For instance, sensor  618  of computer system  624  emits light  618   a , which reflects off of skin of the user associated with computer system  624  (e.g., the user wearing computer system  624  and the same user associated with computer system  600 ). Light  618   a  is reflected from the skin of the user and received by sensor  618  of computer system  624 , which may enable computer system  624  (and/or computer system  600 ) to determine changes in blood volume of the user associated with computer system  624 . In addition, sensor  620  is a gyro sensor and/or an accelorometer that collects data indicative of movement (e.g., angular velocity)  620   a  of the user associated with computer system  624 . Further still, sensor  622  is an electrocardiogram (ECG) sensor and/or a heart rate sensor that collects data indicative of a heart rate of the user associated with computer system  624 . 
     Accordingly, sensors  618 ,  620 , and  622  of computer system  624  do not directly measure pressure and/or blood pressure of the user associated with computer system  624 . In particular, sensors  618 ,  620 , and  622  do not provide computer system  624  and/or computer system  600  with raw data that includes pressure and/or blood pressure. Further, computer system  624  and/or sensors  618 ,  620 , and  622  of computer system  624  do not apply pressure to, and/or restrict blood flow of, the user associated with computer system  624 . Further still, sensors  618 ,  620 , and  622  do no measure vibration. Therefore, sensors  618 ,  620 , and  622 , either alone or collectively, are not traditional blood pressure measurement devices, such as a sphygmomanometer, which measures pressure, vibration, and/or acoustics associated with blood flowing through arteries and/or blood vessels. Instead, sensors  618 ,  620 , and  622  provide data associated with light absorption of the skin of the user, movement of the user, and/or a heart rate of the user to computer system  624  and/or computer system  600 . That data received from sensors  618 ,  620 , and  622  is then input into an algorithm to determine the risk score of the data collected over the predetermined period, which is then compared to the threshold risk score. 
     Further, the data collected by sensors  618 ,  620 , and  622  is passively measured. In other words, computer system  624  causes sensors  618 ,  620 , and  622  to collect the data while the user wears computer system  624  and without the user providing an input each time a data point is measured. Therefore, the user associated with computer system  624  (e.g., the same user associated with computer system  600 ) can enable hypertension notifications via the set-up process described above with respect to  FIGS. 6A-6F  and not provide any further inputs to computer system  600  and/or computer system  624  in order for computer system  600  and/or computer system  624  to collect the data over the predetermined period of time. 
     As set forth above, data measured and/or collected from sensors  618 ,  620 , and  622  is received by computer system  624  and/or computer system  600  (e.g., via computer system  624 ). Computer system  624  and/or computer system  600  utilizes the data collected over the predetermined period of time to determine whether the set of notification criteria is met (e.g., whether the risk score generated by the algorithm using the data exceeds the threshold risk score). In response to determining that the data collected over the predetermined period of time satisfies the set of notification criteria, computer system  600  and/or computer system  624  generate a notification indicating that the user associated with computer system  600  and computer system  624  is at risk for hypertension. 
     At  FIG. 6H , computer system  600  displays notification  628  on user interface  630  (e.g., a lock screen user interface and/or a home screen user interface). Computer system  600  displays notification  628  on a second date (e.g., Tuesday, May 5th), which is a date that occurs after the predetermined period of time has elapsed starting from the first date (e.g., Sunday, April 5th). Accordingly, computer system  600  (and/or computer system  624 ) determines that the data collected during the predetermined period of time (e.g., as shown at  FIG. 6G ) satisfies the set of notification criteria, thereby causing display of notification  628 . At  FIG. 6H , notification  628  includes application indicator  628   a  and information indicator  628   b . Application indicator  628   a  includes graphical user interface elements and/or text indicative of an application (e.g., a health application) of computer system  600  that is associated with notification  628 . In addition, information indicator  628   b  provides details (e.g., textual details) indicating that the notification  628  pertains to the user being at risk for hypertension. As shown at  FIG. 6H , notification  628  does not include an indication of a blood pressure measurement of the user (e.g., a numeric indicator and/or quantitative value of systolic and/or diastolic pressure), but instead notifies the user that data collected indicates that the user is at risk for hypertension. 
     In some embodiments, computer system  600  and/or computer system  624  reset the predetermined period of time after generating notification  628 . As such, computer system  600  and/or computer system  624  does not generate another notification indicating that the user is at risk of hypertension until collecting another set of data within a second predetermined period of time (e.g., 30 days; a predetermined period of time that does not overlap with the predetermined period of time used to generate notification  628 ). For example, computer system  600  generates and displays notification  628  on Tuesday, May 5th. Computer system  600  and/or computer system  624  resets the predetermined period of time, such that a second notification is not generated and/or displayed until after the predetermined period of time elapses again starting from Tuesday, May 5th. In other words, the predetermined period of time for collecting data that is used to generate a first hypertension notification does not overlap with the predetermined period of time for collecting data that is used to generate a second hypertension notification. 
     In particular, at  FIG. 6I , computer system  600  displays notification  632  on user interface  630  (e.g., a lock screen user interface). Computer system  600  displays notification  632  on a third date (e.g., Friday, June 5th), which occurs after the predetermined period of time (e.g., 30 days) has elapsed starting from the second date (e.g., Tuesday, May 5th). As such, computer system  600  and/or computer system  624  resets the predetermined period of time in response to generating and displaying notification  628 , such that a subsequent notification (e.g., notification  632 ) is not generated and/or displayed until after the predetermined period of time has elapsed starting from the time notification  628  was generated. At  FIG. 6I , notification  632  includes application indicator  632   a  and information indicator  632   b . Application indicator  632   a  includes graphical user interface elements and/or text indicating an application (e.g., a health application) of computer system  600  that is associated with notification  632 . In addition, information indicator  632   b  provides details (e.g., textual details) indicating that the notification  632  pertains to the user being at risk for hypertension. As shown at  FIG. 6I , notification  632  does not include an indication of a blood pressure measurement of the user (e.g., a numeric indicator and/or quantitative value of systolic and/or diastolic pressure), but instead notifies the user that data collected indicates that the user is at risk for hypertension. 
     At  FIG. 6I , computer system  600  detects user input  650   f  (e.g., a tap gesture and/or user input satisfying a set of unlock criteria) on notification  632 . In response to detecting user input  650   f , computer system  600  displays health event user interface  634 , as shown at  FIG. 6J . Health event user interface  634  corresponds to notification  632  and provides further information and/or details associated with notification  632 . Similar to notification  632 , health event user interface  634  does not include a blood pressure measurement of the user, such as a numeric and/or quantitative value of a systolic and/or a diastolic pressure measurement. Instead, health event user interface  634  includes information region  634   a , notification details region  636 , and device details region  638 . Information region  634   a  provides textual indications related to the cause for computer system  600  displaying notification  632  and additional information for the user to consider as a result of the notification  632 . Notification details region  636  includes date user interface object  636   a  indicating a date and time that notification  632  was generated by computer system  600  (and/or computer system  624 ), source user interface object  636   b  indicating the application of computer system  600  associated with notification  632  (e.g., the health application), and log user interface object  636   c  indicating a date and time that notification was logged, stored, and/or otherwise recorded by the application indicated by source user interface object  636   b . Device details region  638  provides one or more user interface objects indicative of a particular device (e.g., computer system  600  and/or computer system  624 ) that generated notification  632 . 
     In some embodiments, the user of computer system  600  can access health event user interface  634  via health user interface  604  in addition to, or in lieu of, user input  650   f . For instance, at  FIG. 6K , computer system  600  displays health user interface  604 , which includes notification  640 . Notification  640  corresponds to notification  632 , and thus, computer system  600  displays notification  640  in response to a determination (e.g., by computer system  600  and/or computer system  624 ) that data collected over the predetermined period of time satisfies the set of notification criteria for generating a hypertension notification. At  FIG. 6K , notification  640  includes an indication (e.g., textual indication) providing the user with information related to the cause of notification  640 . In addition, notification  640  includes learn more user interface object  640   a . In response to detecting user input corresponding to selection of learn more user interface object  640   a , computer system  600  displays an educational user interface that provides the user with further information related to hypertension and suggested actions that the user can take as a result of receiving notification  640 . 
     Health user interface  604  of  FIG. 6K  is translated in an upwards direction as compared to health user interface  604  of  FIG. 6A . As such, computer system  600  displays notifications, such as notification  640 , in a notification region  642  of health user interface  604 , where the notifications in notification region  642  are associated with and/or generated by the health application. In some embodiments, notifications region  642  of health user interface  604  is positioned above and/or before health data user interface objects  604   a  and/or  604   b  when computer system  600  launches the health application and displays health user interface  604  (e.g., before receiving a user input requesting to translate health user interface  604 ). Accordingly, the user associated with computer system  600  can easily view recent notifications corresponding to health events and/or health information that are relevant to the user when the health application is launched by computer system  600 . 
     At  FIG. 6K , computer system  600  detects user input  650   g  (e.g., a tap gesture) corresponding to selection of notification  640 . In response to detecting user input  650   g , computer system  600  displays hypertension user interface  644 , as shown at  FIG. 6L . Hypertension user interface  644  is another user interface associated with the health application of computer system  600 , but includes user interface objects that are specifically related to the hypertension notifications and information associated with hypertension and/or the hypertension notifications. For example, hypertension user interface  644  includes status user interface object  644   a , notifications region  646 , and learn more region  648 . Status user interface object  644   a  provides an indication as to the status of the hypertension notifications feature (e.g., whether computer system  600  has enabled and/or activated the hypertension notifications). In some embodiments, status user interface object  644   a  includes an indication (e.g., a textual indication) of a date and/or time when data from sensors  618 ,  620 , and  622  was last collected within the predetermined period of time. 
     Notifications region  646  of hypertension user interface  644  includes first notification user interface object  646   a  and second notification user interface object  646   b . First notification user interface object  646   a  corresponds to notification  632  generated on the third date (e.g., June 5th) and second notification user interface object  646   b  corresponds to notification  628  generated on the second date (e.g., May 5th). As such, computer system  600  displays a history of the hypertension notifications generated by computer system  600  and/or computer system  624  within notifications region  646  of hypertension user interface  644 . Thus, the user associated with computer system  600  and computer system  624  can access and view a history of the hypertension notifications that have been generated by computer system  600  and/or computer system  624 . In some embodiments, notifications region  646  includes more notification user interface objects than the two notification user interface objects  646   a  and  646   b  (e.g., when additional hypertension notifications have been generated by computer system  600  and/or computer system  624 ). In some embodiments, computer system  600  displays the notification user interface objects within notifications region  646  in reverse chronological order (e.g., most recent at the top and least recent at the bottom). In some embodiments, computer system  600  displays a predetermined number of notification user interface objects in notification region  646  and displays a user interface object (e.g., “See All”) that, when selected, causes computer system  600  to display a list of notification user interface objects for all hypertension notifications generated by computer system  600  and/or computer system  624 . In some embodiments, computer system  600  adjusts a size of notifications region  646  on hypertension user interface  644 , such that notification user interface objects corresponding to each respective hypertension notification is displayed on hypertension user interface  644 . 
     In some embodiments, computer system  600  and/or computer system  624  determines that the data collected over the predetermined period of time does not satisfy the set of notification criteria. In response to determining that the data collected over the predetermined period of time does not satisfy the set of notification criteria, computer system  600  forgoes display of notifications  628  and  632 , as well as forgoes display of notification user interface objects  646   a  and  646   b  on hypertension user interface  644 . 
     At  FIG. 6L , computer system  600  detects user input  650   h  (e.g., a tap gesture) corresponding to selection of first notification user interface object  646   a . In response to detecting user input  650   h , computer system  600  displays health event user interface  634 , as shown at  FIG. 6J , which corresponds to notification  632  generated by computer system  600  and/or computer system  624  on the third date (e.g., June 5th). In some embodiments, computer system  600  displays health user interface  634  corresponding to notification  628  generated by computer system  600  and/or computer system  624  on the second date (e.g., May 5th) in response to user input corresponding to selection of second notification user interface object  646   b.    
     In addition, at  FIG. 6L , learn more region  648  of hypertension user interface  644  includes first user interface object  648   a  (e.g., labeled “Things to Know”), second user interface object  648   b  (e.g., labeled “How Hypertension Notifications Work”), and third user interface object  648   c  (e.g., labeled “Learn More” and/or “About Hypertension”). In response to user input corresponding to selection of the user interface objects  648   a ,  648   b , and/or  648   c , computer system  600  displays an educational user interface that provides the user with additional details and/or information related to hypertension, the hypertension notifications, and/or suggested actions for the user as a result of receiving a hypertension notification. 
     At  FIG. 6L , computer system  600  detects user input  650   i  (e.g., a swipe gesture; an upward swipe gesture) on hypertension user interface  644 . In response to detecting user input  650   i , computer system  600  translates hypertension user interface  644  and displays additional options region  652  of hypertension user interface  644  (e.g., displays additional options region  652  concurrently with learn more region  648  and ceases to display notifications region  646 ), as shown at  FIG. 6M . At  FIG. 6M , additional options region  652  includes favorites user interface object  652   a , all data user interface object  652   b , and source user interface object  652   c.    
     In response to user input corresponding to selection of favorites user interface object  652   a , computer system  600  is configured to add a user interface object to health user interface  604  that is displayed in a favorites region (e.g., a region of health user interface  604  that includes health data user interface objects  604   a  and/or  604   b ). As such, information related the hypertension notifications may be included on health user interface  604  after the hypertension notifications are enabled and/or activated and regardless of whether a hypertension notification was recently generated (e.g., by computer system  600  and/or computer system  624 ). 
     In response to user input corresponding to all data user interface object  652   b , computer system  600  displays a list of dates and/or times at which data was collected and/or measured by sensors  618 ,  620 , and  622  of computer system  624 . In some embodiments, computer system  600  displays additional information (e.g., a measurement value(s), a device used to collect the data, a date and/or time at which the data was added to the health application, and/or a test type) in response to user input corresponding to selection of an item of the list of dates and/or times at which data was collected. 
     In response to user input corresponding to source user interface object  652   c , computer system  600  displays an additional user interface having information related to computer systems and/or devices used to collect and/or measure data for use in determining whether to generate the hypertension notifications. In some embodiments, the additional user interface also includes information related to other applications (e.g., applications different from the health application), devices, and/or software for which the user has provided access to the data used by computer system  600  and/or computer system  624  to determine whether to generate the hypertension notifications. 
     In some embodiments, computer system  624  is also configured to generate and display notifications in response to a determination that the data collected over the predetermined period of time satisfies the set of notification criteria. For instance, at  FIG. 6N , computer system  624  includes display generation component  654  and computer system  624  displays, via display generation component  654 , notification  656 . Notification  656  can be generated by computer system  624  and/or computer system  600  and can be displayed at the same time as one of notifications  628 ,  632 . As such, the user can be notified about a potential hypertension event on both computer system  600  and computer system  624 . 
     At  FIG. 6N , computer system  624  detects user input  650   j  (e.g., a tap gesture) on notification  656 . In response to detecting user input  650   j , computer system  624  displays, via display generation component  654 , notification user interface  658 , as shown at  FIG. 6O . Notification user interface  658  includes an indication  658   a  (e.g., a textual indication) related to the notification and a learn more user interface object  658   b . As set forth above, notification  656  and notification user interface  658  do not include a blood pressure measurement (e.g., a numeric and/or quantitative value representing a systolic and/or diastolic blood pressure) of the user. Instead, notification  656  and notification user interface  658  inform the user that the data collected over the predetermined period of time suggests that the user may have hypertension (e.g., the user is at risk of hypertension based on the data collected over the predetermined period of time). In some embodiments, notification user interface  658  includes indication  658   a , which may correspond to information region  634   a  of health event user interface  634 . However, notification user interface  658  does not include the information provided in notification details region  636  and device details region  638  of health event user interface  634 . As such, indication  658   a  may prompt the user to use computer system  600  to display health user interface  604  and/or health event user interface  634  to ultimately obtain the information provided in notification details region  636  and device details region  638  of health event user interface  634 . 
     At  FIG. 6O , computer system  624  detects user input  650   k  (e.g., a tap gesture) on learn more user interface object  658   b . In response to detecting user input  650   k , computer system  624  displays educational user interface  660 , as shown at  FIG. 6P . Educational user interface  660  provides an indication (e.g., a textual indication) related to information about hypertension, suggested actions for the user to take as a result of receiving notification  656 , and/or information about how notification  656  was generated. 
       FIG. 7  is a flow diagram illustrating a method for generating a notification associated with a health event using an electronic device in accordance with some embodiments. Method  700  is performed at a device (e.g.,  100 ,  300 ,  500 ) with one or more output devices and one or more sensors. 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 generating a notification associated with a health event. The method reduces the cognitive burden on a user for accessing information about the health event, thereby creating a more efficient human-machine interface. For battery-operated computing devices, enabling a user to access information about the health event faster and more efficiently conserves power and increases the time between battery charges. 
     Computer system (e.g.,  100 ,  300 ,  500 ,  600 , and/or  624 ) (e.g., an electronic device; a smart device, such as a smart watch or a smart phone; a mobile device; a wearable device) is in communication with one or more output devices (e.g.,  602  and/or  654 ) (e.g., a display generation component (a display, such as a touchscreen display); an audio generation component (e.g., audio circuitry; an integrated speaker; a connected speaker); a haptic output component (e.g., a haptic feedback controller; a haptic motor)) and one or more sensors (e.g.,  618 ,  620 , and/or  622 ) (e.g., a photoplethysmogram sensor, a gyro sensor, and/or an electrocardiogram sensor). In some embodiments, the one or more sensors do not include a sensor for directly and/or specifically measuring a pressure value of a user of the computer system. 
     Computer system receives ( 702 ) first data associated with a user of the computer system from the one or more sensors (e.g.,  618 ,  620 , and/or  622 ) (e.g., periodically and/or intermittently receiving measurement data from the one or more sensors, where the data from the one or more sensors includes data indicative of light absorption of skin of a user associated with the computer system (e.g., one or more measurements received from a photoplethysmogram sensor), data indicative of orientation and/or angular velocity of the computer system (e.g., one or more measurements received from a gyro sensor), and/or data indicative of voltage over time (e.g., one or more measurements of electrical activity of the heart received from an electrocardiogram sensor)). The first data from the one or more sensors (e.g.,  618 ,  620 , and/or  622 ) does not include a direct measurement of pressure (e.g., a value from a sensor that is configured to specifically measure pressure, such as a manometer, a pressure transducer, a strain gauge, and/or a piezometer). In some embodiments, the data from the one or more sensors is data from (e.g., generated by; relating to; about) a user of the computer system. In some embodiments, the data from the one or more sensors includes an indirect measurement of pressure. For instance, raw data from the one or more sensors may be utilized (e.g., as seeds of an algorithm) to calculate and/or estimate pressure, such as systolic blood pressure and/or diastolic blood pressure. In some embodiments, the computer system does not use the data to indirectly determine and/or calculate a numerical measurement of pressure. 
     In response to receiving the first data from the one or more sensors ( 704 ) (e.g.,  618 ,  620 , and/or  622 ) and in accordance with a determination that the first data from the one or more sensors (e.g.,  618 ,  620 , and/or  622 ) satisfies a set of hypertension notification criteria (e.g., the computer system uses the data from the one or more sensors to make an assessment as to whether the user associated with the computer system is at risk for chronic hypertension (e.g., the user associated with the computer system has consistently high blood pressure as opposed to one instance, one estimation, and/or one measurement of blood pressure that is considered high blood pressure); the computer system uses the data from the one or more sensors to generate a risk score indicative of chronic hypertension and the risk score exceeds a threshold value), computer system generates ( 706 ) (e.g., outputting; providing; displaying), via the one or more output devices (e.g.,  602  and/or  654 ), a notification (e.g.,  628 ,  632 ,  656 ) indicative of a hypertension event (e.g., the data from the one or more sensors indicates that the user associated with the computer system is at risk for chronic hypertension as opposed to one instance (e.g., one measurement and/or one estimation) of high blood pressure) associated with the user of the computer system (e.g., the computer system generates a notification that is displayed by the display generation component of the computer system (e.g., a smart watch) and/or the computer system is in communication with an external device (e.g., a smart phone) and generates a signal received by the external device that causes the external device to display a notification on a display generation component of the external device). In some embodiments, the set of hypertension notification criteria do not include a criterion (e.g., do not include any criterion) based on (e.g., that take into account) a blood pressure value (e.g., diastolic and/or systolic value of a user of the computer system). In some embodiments, the set of hypertension notification criteria do not include a criterion (e.g., any criterion) based on a pressure measurement. 
     In response to receiving the first data from the one or more sensors ( 704 ) (e.g.,  618 ,  620 , and/or  622 ) and in accordance with a determination that the first data from the one or more sensors (e.g.,  618 ,  620 , and/or  622 ) does not satisfy the set of hypertension notification criteria (e.g., the computer system uses the data from the one or more sensors to make an assessment as to whether the user associated with the computer system is at risk for chronic hypertension (e.g., the user associated with the computer system does not have consistently high blood pressure); the computer system uses the data from the one or more sensors to generate a risk score indicative of chronic hypertension and the risk score does not exceed the threshold value), computer system forgoes ( 708 ) generating the notification (e.g.,  628 ,  632 ,  656 ) of the hypertension event (e.g., a notification is not displayed by the computer system and the external device because the data from the one or more sensors indicates that the user associated with the computer system is not at risk for chronic hypertension). 
     Conditionally generating a notification indicative of a hypertension event provides the user with feedback regarding the received first data and the relationship of that data to the set of hypertension notification criteria. Providing improved user feedback enhances the operability of the computer system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the system by enabling the user to use the computer system more quickly and efficiently. 
     In some embodiments, the first data associated with a user of the computer system includes data received from the one or more sensors (e.g.,  618 ,  620 , and/or  622 ) over a first period of time that is selected from the group consisting of: a period of greater than 1 hour; a period of greater than 1 day; and a period of greater than 1 week. In some embodiments, the first data is intermittent sensor data from the period of time. In some embodiments, the intermittent data is collected at regular intervals. In some embodiments, the intermittent data is collected at irregular levels. In some embodiments, the first data is continuous sensor data from the period of time. 
     In some embodiments, the first data associated with a user of the computer system includes a plurality of subsets of data (e.g., the first data is intermittently-collected data) that includes: a first subset of data that is received over a second period of time (e.g., a measurement time window (e.g., 1 second)); and a second subset of data that is received starting after a third period of time (e.g., a time interval between the collection of the first and second subsets of data (e.g., a period of 10 seconds after collecting the first subset of data)) has elapsed after receiving the first subset of data (e.g., after the end of the first period of time). The third period of time is greater than the second period of time. 
     Conditionally generating a notification based on data that collected over multiple periods of time reduces the risk of transient errors in data collection and decreases the risk of erroneous notifications. Reducing the occurrence of erroneous notifications enhances the operability of the computer system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the system by enabling the user to use the computer system more quickly and efficiently. 
     In some embodiments, the set of hypertension notification criteria includes a criterion that is satisfied when a risk score (e.g., a quantitative value derived or calculated based on the data) exceeds a threshold value (e.g., an empirically-derived value calculated based a plurality of clinical patients, including patients diagnosed with hypertension and patients that are not diagnosed with hypertension). The risk score is generated based on the first data associated with the user of the computer system. 
     In some embodiments, the one or more sensors (e.g.,  618 ,  620 , and/or  622 ) are selected from the group consisting of a photoplethysmogram sensor, a gyroscopic sensor, an electrocardiogram sensor, an accelerometer, and a combination thereof. 
     In some embodiments, the first data associated with the user of the computer system does not include data from a vibration sensor. In some embodiments, the one or more sensors do not include a sensor (e.g., do not include any sensor) that measures vibrations and/or pressure values. 
     In some embodiments, the computer system is not in communication with (e.g., does not include) a component (e.g., any component) that actively applies mechanical pressure (e.g., a blood pressure cuff) to the user of the computer system. In some embodiments, the one or more sensors (e.g.,  618 ,  620 , and/or  622 ) do not include a sensor (e.g., do not include any sensor) (e.g., a pressure sensor) that measures data within a fourth period of time (e.g., 1 second, 30 seconds, 1 minute, 1 hour) after active, mechanical pressure is applied to the user of the computer system. 
     In some embodiments, the user of the computer system satisfies a set of feature-eligibility criteria. In some embodiments, the feature-eligibility criteria includes a criterion that is satisfied when the user has been determined to be over a first age (e.g., over 22 years of age). In some embodiments, the method further comprises determining an age of the user (e.g., receiving an input corresponding to the age of the user; receiving data from an external electronic device, data corresponding to the age of the user). In some embodiments, if the user of the computer system does not satisfy the set of feature-eligibility criteria, the notification(s) indicative of a hypertension event are not generated by the computer system. In some embodiments, if the user of the computer system does not satisfy the set of feature-eligibility criteria, no data is collected from the sensors for the purposes of determining whether to provide notification(s) indicative of a hypertension event and no determinations are made based on the set of hypertension notification criteria. 
     In some embodiments, the set of hypertension notification criteria includes a criterion that is satisfied when the user of the computer system satisfies a set of feature-eligibility criteria. In some embodiments, the feature-eligibility criteria includes a criterion that is satisfied when the user has been determined to be over a first age (e.g., over 22 years of age). 
     Conditionally generating a notification based on data for users that satisfy a set of feature-eligibility criteria reduces the risk of generating erroneous notifications (e.g., resulting from errors due to the user not being eligible). Reducing the occurrence of erroneous notifications enhances the operability of the computer system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the system by enabling the user to use the computer system more quickly and efficiently. 
     In some embodiments, computer system receiving the first data associated with the user of the computer system from the one or more sensors (e.g.,  618 ,  620 , and/or  622 ) includes computer system receiving the first data over a first predetermined time period (e.g., a 1 day period; a 7 day period; a fifteen day period; a 30 day period). In some embodiments, the set of hypertension notification criteria includes a criterion that is satisfied when data has been collected for at least the predetermined time period. 
     In some embodiments, after computer system receives the first data associated with the user of the computer system from the one or more sensors (e.g.,  618 ,  620 , and/or  622 ) over the first predetermined time period, computer system receives second data associated with the user of the computer system from the one or more sensors (e.g.,  618 ,  620 , and/or  622 ), wherein the second data is received over a second predetermined period of time that does not overlap the first predetermined period of time (e.g., a period of time equal to the first predetermined period of time). In response to computer system receiving the second data from the one or more sensors and in accordance with a determination that the second data from the one or more sensors satisfies the set of hypertension notification criteria, computer system generates, via the one or more output devices (e.g.,  602  and/or  654 ), a second notification (e.g.,  632 ) indicative of a hypertension event associated with the user of the computer system. 
     In some embodiments, the first data and the second data are non-overlapping sets of data. In some embodiments, a first notification indicative of a hypertension event can be issued (e.g., issued if the first data satisfies the set of hypertension notification criteria) based on the first data and a second notification indicative of a hypertension event can be issued (e.g., issued if the second data satisfies the set of hypertension notification criteria) based on the second data. In some embodiments, the first data is stored in a first data buffer until the first predetermined time period elapses and the computer system resets the first data buffer prior to receiving the second data and storing the second data in the first data buffer. 
     Conditionally generating first and second notifications based on separate data sets collected makes the first and second notifications independent and reduces the risk that transient, aberrant data will affect multiple notifications. Generating independent notifications and reducing the occurrence of erroneous notifications enhances the operability of the computer system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the system by enabling the user to use the computer system more quickly and efficiently. 
     In some embodiments, the one or more output devices (e.g.,  602  and/or  654 ) includes a display generation component (e.g.,  602  and/or  654 ) and the computer system is in communication with one or more input devices (e.g.,  602  and/or  654 ) (e.g., a touch-sensitive surface, a mouse, a microphone). Computer system receives a first set of one or more inputs (e.g.,  650   f ), via the one or more input devices (e.g.,  602 ), corresponding to the notification (e.g.,  628 ) (e.g., a touch gesture or mouse click on a displayed notification that is user-selectable graphical object; a verbal command received after an audio notification is outputted). In response to the first set of one or more inputs (e.g.,  650   f ), computer system displays, via the display generation component (e.g.,  602 ), a first user interface (e.g.,  634 ) that includes first information (e.g.,  634   a ,  636   a ,  636   b ,  636   c , and/or  638 ) corresponding to the first data (e.g., information on when the data was received; information on the sensor(s); values for the first data and/or subsets of the first data). 
     Displaying an interface with additional information corresponding to the first data provides the user with feedback regarding the received first data. Providing improved user feedback enhances the operability of the computer system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the system by enabling the user to use the computer system more quickly and efficiently. 
     In some embodiments, the one or more output devices (e.g.,  602  and/or  654 ) includes a display generation component (e.g.,  602  and/or  654 ). After computer system generates the notification (e.g.,  628 ,  632 , and/or  656 ) indicative of a hypertension event, computer system displays a second user interface (e.g.,  644 ) that includes information (e.g.,  646   a  and/or  646   b ) (e.g., a time when the notification was generated; a total of notifications that have been generated; data used to generate the notification) corresponding to one or more notifications (e.g.,  628 ,  632 , and/or  656 ) indicative of hypertension events, including the notification (e.g.,  628 ,  632 , and/or  656 ) indicative of a hypertension event. In some embodiments, the second user interface includes a set of one or more user-selectable graphical objects that affect one or more settings associated with notifications indicative of hypertension events (e.g., a frequency of notifications, a duration of notifications, one or more criterion of the set of hypertension notification criteria). 
     Displaying a second interface with information corresponding to the notification indicative of a hypertension event provides the user with additional feedback about the notification and the data received by the system. Providing improved user feedback enhances the operability of the computer system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the system by enabling the user to use the computer system more quickly and efficiently. 
     In some embodiments, the notification (e.g.,  628 ,  632 , and/or  656 ) indicative of a hypertension event does not include a numerical (e.g., quantitative) indication of a blood pressure value of a user of the computer system. In some embodiments, the notification does not include any numerical or quantitative values. In some embodiments, the notification only includes non-numerical information. 
     In some embodiments, the first data associated with a user of the computer system includes a second plurality of subsets of data (e.g., the first data is intermittently-collected data) that includes a third subset of data that is received at a first time and a fourth subset of data that is received a second predetermined period of time after receiving the third subset of data (e.g., at a second time that is a predetermined time). The third subset of data is not received in response to user input (e.g., any user input; the first time is predetermined time; the third subset of data is received independently of user input (e.g., is automatically received)). In some embodiments, the fourth subset of data is not received in response to user input (e.g., any user input; the second time is predetermined time; the fourth subset of data is received independently of user input (e.g., is automatically received)). 
     Conditionally generating a notification based on separate data sets collected automatically over time reduces the risk of erroneous notifications and of missing the collection of data. Reducing the occurrence of erroneous notifications and reducing the risk of missed data collection enhances the operability of the computer system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the system by enabling the user to use the computer system more quickly and efficiently. 
     Note that details of the processes described above with respect to method  700  (e.g.,  FIG. 7 ) are also applicable in an analogous manner to the methods described below. For example, method  900  optionally includes one or more of the characteristics of the various methods described above with reference to method  700 . For example, notifications generated via method  700  can be used to prompt a user to initiate a data collection log for a predefined period of time, as set forth in method  900 . For brevity, these details are not repeated below. 
       FIGS. 8A-8U  illustrate exemplary user interfaces for managing health information over a predefined period of time, in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in  FIG. 9 . 
       FIG. 8A  illustrates computer system  600  having display generation component  602  and displaying, via display generation component  602 , health user interface  604  of the health application of computer system  600  on a first date (e.g., Monday, May 11th). At  FIG. 8A , health user interface  604  includes first health data user interface object  604   a  and third health data user interface object  604   c . First health data user interface object  604   a  includes information related to a first health parameter (e.g., “Weight”) of a user associated with computer system  600  and third health data user interface object  604   c  includes information related to a second health parameter (e.g., “Blood Pressure”) of a user associated with computer system  600 . In some embodiments, health user interface  604  is a home screen or a default screen of the health application that computer system  600  displays, via display generation component  602 , upon launching the health application. In some embodiments, health user interface  604  includes more than two health data user interface objects or one health data user interface object. 
     At  FIG. 8A , computer system  600  detects user input  850   a  (e.g., a tap gesture) corresponding to selection of third health data user interface object  604   c . In response to detecting user input  850   a , computer system  600  displays blood pressure user interface  800  on the first date, as shown at  FIG. 8B . Blood pressure user interface  800  includes blood pressure graphical element  802  (e.g., a graph) that includes a visual indication (e.g., a set of data points corresponding to systolic pressure and diastolic pressure) of one or more blood pressure measurements received by computer system  600 , if available. Computer system  600  is not configured to measure blood pressure (e.g., apply pressure to the user and/or measure a pressure and/or vibration value) of a user associated with the computer system  600 . Instead, computer system  600  receives blood pressure data (e.g., blood pressure measurements) via user input and/or via an external device (e.g., a blood pressure measurement device in communication with computer system  600 ). 
     Blood pressure data received by computer system  600  is included on blood pressure graphical element  802 . At  FIG. 8B , blood pressure user interface  800  also includes information user interface object  803 . In response to detecting user input corresponding to selection of information user interface object  803 , computer system  600  displays an indication of a particular standard and/or rating system associated with the blood pressure data received by computer system  600  and/or displayed on blood pressure graphical element  802 . For instance, different countries, regions, and/or areas around the world utilize different rating systems for measuring blood pressure and/or determining whether a person has high, low, and/or normal blood pressure. Accordingly, information user interface object  803  enables computer system  600  to display indicators that provide information as to the particular standard and/or rating system applicable to the blood pressure data corresponding to blood pressure user interface  800 . 
     In some embodiments, computer system  600  filters the blood pressure data displayed on blood pressure graphical element  802 . For instance, blood pressure user interface  800  includes date filter  804 , which enables computer system  600  to adjust a time scale of blood pressure graphical element  802  and filter blood pressure data displayed on blood pressure graphical element  802  based on date. At  FIG. 8B , date filter  804  includes day filter  804   a , week filter  804   b , month filter  804   c , and year filter  804 . In some embodiments, date filter  804  may include other suitable periods of time for filtering blood pressure data. At  FIG. 8B , day filter  804   a  of date filter  804  is activated (e.g., selected), and thus, computer system  600  displays all blood pressure data received by computer system  600  for a particular day (e.g., the current day) on blood pressure graphical element  802 . In response to detecting user input on week filter  804   b , computer system  600  displays all blood pressure data received by computer system  600  for a particular week (e.g., a week that includes the current day) on blood pressure graphical element  802 . In response to detecting user input on month filter  804   c , computer system  600  displays all blood pressure data received by computer system  600  for a particular month (e.g., a month that includes the current day) on blood pressure graphical element  802 . Similarly, in response to detecting user input on year filter  804   d , computer system  600  displays all blood pressure data received by computer system for a particular year (e.g., a year that includes the current day) on blood pressure graphical element  802 . 
     In addition to filtering blood pressure data by the time at which it was received by computer system  600  and/or a time stamp associated with the blood pressure data, computer system  600  is also configured to provide indications of particular blood pressure ranges (e.g., normal blood pressure ranges, low blood pressure ranges, and/or high blood pressure ranges) on blood pressure graphical element  802 . Thus, a user can visually compare his or her blood pressure data to various blood pressure ranges to better understand his or her health. At  FIG. 8B , computer system detects user input  850   b  (e.g., a tap gesture) corresponding to selection of filter user interface object  806  of blood pressure user interface  800 . In response to detecting user input  850   b , computer system  600  displays indicators of a normal blood pressure range on blood pressure graphical element  802  on the first date, as shown at  FIG. 8C . 
     At  FIG. 8C , blood pressure graphical element  802  includes first indicator  808  and second indicator  810 , which represent an upper limit (e.g., first indicator  808 ) and a lower limit (e.g., second indicator), respectively, for a normal range of a first portion (e.g., systolic pressure) of a blood pressure measurement. In addition, blood pressure graphical element  802  includes third indicator  812  and fourth indicator  814 , which represent an upper limit (e.g., third indicator  812 ) and a lower limit (e.g., fourth indicator  814 ), respectively, for a normal range of a second portion (e.g., diastolic pressure) of a blood pressure measurement. As such, computer system  600  is configured to display indications of various blood pressure ranges in response to user input on filter user interface object  806 , such that the user associated with computer system  600  can easily compare his or her blood pressure measurements to normal blood pressure ranges, low blood pressure ranges, and/or high blood pressure ranges. 
     At  FIG. 8C , blood pressure user interface  800  also includes blood pressure log user interface object  816 . As set forth in detail below, in response to user input corresponding to selection of blood pressure log user interface object  816 , computer system  600  is configured to activate and/or initiate a schedule for recording blood pressure measurements over a selected time range. In response to activation and/or initiation of the schedule, computer system  600  generates notifications to remind the user to input and/or otherwise provide blood pressure measurements to computer system  600  over the selected time range. As such, the schedule for recording blood pressure measurements facilitates a user&#39;s ability to track his or her blood pressure over the selected time range, thereby improving the user&#39;s understanding of his or her health. 
     At  FIG. 8C , computer system  600  detects user input  850   c  (e.g., a tap gesture) corresponding to selection of blood pressure log user interface object  816 . In response to detecting user input  850   c , computer system  600  initiates a set-up process for activating the schedule for recording blood pressure measurements and displays first set-up user interface  818  on the first date, as shown at  FIG. 8D . At  FIG. 8D , first set-up user interface  818  includes textual indications that provide the user with information related to the schedule for recording blood pressure measurements. At  FIG. 8D , computer system  600  detects user input  850   d  (e.g., a tap gesture) corresponding to selection of set-up user interface object  818   a  of first set-up user interface  818 . In response to detecting user input  850   d , computer system  600  displays second set-up user interface  820  on the first date, as shown at  FIG. 8E . Second set-up user interface  820  includes textual indications related to blood pressure measurement devices (e.g., manual blood pressure measurement devices and/or Bluetooth blood pressure measurement devices) that the user can utilize to measure his or her blood pressure. At  FIG. 8E , computer system  600  detects user input  850   e  (e.g., a tap gesture) corresponding to selection of next user interface object  820   a  of second set-up user interface  820 . In response to detecting user input  850   e , computer system  600  displays third set-up user interface  822  on the first date, as shown at  FIG. 8F . 
     At  FIG. 8F , third set-up user interface  822  includes first time range user interface object  822   a , second time range user interface object  822   b , and next user interface object  822   c . Computer system  600  can initiate the schedule for recording blood pressure measurements over different time ranges based on user selection of first time range user interface object  822   a  or second time range user interface object  822   b . At  FIG. 8F , first time range user interface object  822   a  corresponds to a first time range of seven days and second time range user interface object  822   b  corresponds to a second time range of 30 days. As set forth below, the schedule for recording blood pressure measurements over the first time range can include a first number of number of blood pressure measurements, such as two blood pressure measurements per day over the seven day range. The schedule for recording blood pressure measurements over the second time range can include a second number of blood pressure measurements, different from the first number of blood pressure measurements, such as one blood pressure measurement per day over the 30 day range. As such, computer system  600  determines different periods of time (e.g., half of one day or one full day) within the selected time range for recording respective blood pressure measurements based on which time range is selected. 
     At  FIG. 8F , computer system  600  detects user input  850   f  (e.g., a tap gesture) corresponding to selection of first time range user interface object  822   a . In some embodiments, in response to detecting user input  850   f , computer system  600  displays indicator  824  on first time range user interface object  822   a  indicating that the first time range associated with first time range user interface object  822   a  is selected. After detecting user input  850   f , computer system  600  detects user input  850   g  (e.g., a tap gesture) corresponding to selection of next user interface object  822   c . After detecting user input  850   g  (and, optionally, after detecting user inputs  850   i ,  850   j , and/or  850   k  described below with reference to  FIGS. 8G-8I ), computer system  600  displays blood pressure user interface  800 , as shown at  FIG. 8J . 
     Alternatively, at  FIG. 8F , computer system  600  detects user input  850   h  (e.g., a tap gesture) corresponding to selection of second time range user interface object  822   b . In some embodiments, in response to detecting user input  850   h , computer system  600  displays indicator  824  on second time range user interface object  822   b  (e.g., instead of on first time range user interface object  822   a ) indicating that the second time range associated with second time range user interface object  822   b  is selected. After detecting user input  850   h , computer system detects user input  850   g  corresponding to selection of next user interface object  822   c . After detecting user input  850   g  (and, optionally, after detecting user inputs  850   i ,  850   j , and/or  850   k  described below with reference to  FIGS. 8G-8I ), computer system  600  displays blood pressure user interface  800 , as shown at  FIG. 8K . In some embodiments, computer system  600  deactivates and/or forgoes display of next user interface object  822   c  before computer system  600  detects user input  850   f  or user input  850   h . Accordingly, computer system  600  does not process and/or detect user input  850   g  until after receiving user input corresponding to selection of one of first time range user interface object  822   a  or second time range user interface object  822   b.    
     While  FIG. 8F  shows selection of a time range for the schedule for recording blood pressure measurements as user interface objects  822   a  and  822   b , in some embodiments, third set-up user interface  822  includes, in addition to user interface objects  822   a  and  822   b  and/or in lieu of user interface objects  822   a  and  822   b , a user interface object enabling a user to enter a custom time range via a keyboard or other input device. 
     At  FIG. 8F , in response to detecting user input  850   g , computer system  600  displays fourth set-up user interface  826  on the first date, as shown at  FIG. 8G . Fourth set-up user interface  826  includes textual indications that inform the user that computer system  600  generates notifications reminding the user to input blood pressure measurements in accordance with the schedule and/or the selected time range. In some embodiments, fourth set-up user interface  826  includes one or more user interface objects that, when selected, cause computer system  600  to deactivate notification reminders associated with the schedule for recording blood pressure measurements. At  FIG. 8G , computer system  600  detects user input  850   i  (e.g., a tap gesture) corresponding to selection of next user interface object  826   a  of fourth set-up user interface  826 . In response to detecting user input  850   i , computer system  600  displays fifth set-up user interface  828  on the first date, as shown at  FIG. 8H . Fifth set-up user interface  828  includes textual indications that provide information to the user on how to measure blood pressure to obtain a blood pressure measurement that is ultimately provided to computer system  600  (e.g., via user input and/or transmission from an external device). At  FIG. 8H , computer system  600  detects user input  850   j  (e.g., a tap gesture) corresponding to selection of next user interface object  828   a  of fifth set-up user interface  828 . In response to detecting user input  850   j , computer system  600  displays sixth set-up user interface  830  on the first date, as shown at  FIG. 8I . 
     Sixth set-up user interface  830  includes log blood pressure measurement user interface object  830   a  and skip blood pressure measurement user interface object  830   b . As such, sixth set-up user interface  830  enables a user to provide a first blood pressure measurement for the schedule (e.g., via selection of log blood pressure measurement user interface object  830   a ) and/or complete the set-up and provide the first blood pressure measurement for the schedule at a time after the current time (e.g., via selection of skip blood pressure measurement user interface object  830   b ). At  FIG. 8I , computer system  600  detects user input  850   k  (e.g., a tap gesture) corresponding to selection of skip blood pressure measurement user interface object  830   b . In response to detecting user input  850   k , computer system  600  displays blood pressure user interface  800  on the first date, as shown at  FIGS. 8J and 8K . As set forth below, computer system  600  displays blood pressure user interface  800  including first schedule user interface object  832  ( FIG. 8J ) corresponding to the first time range or second schedule user interface object  834  ( FIG. 8K ) corresponding to the second time range based on computer system  600  detecting user input  850   f  or  850   h  at  FIG. 8F . 
     Alternatively, at  FIG. 8I , computer system  600  detects user input  850   l  (e.g., a tap gesture) corresponding to selection of log blood pressure measurement user interface object  830   a . In response to detecting user input  850   l , computer system  800  displays measurement input user interface  854 , as shown at  FIG. 8O . 
     Turning now to  FIG. 8J , computer system  600  detects user input  850   f  corresponding to selection of first time range user interface object  822   a  and displays blood pressure user interface  800  having first schedule user interface object  832  on the first date. First schedule user interface object  832  corresponds to the schedule being over the first time range of seven days. Accordingly, first schedule user interface object  832  includes day indicators  832   a - 832   g  corresponding to respective days of a week. In addition, first schedule user interface object  832  includes first interval indicator  832   h  and second interval indicator  832   i . Because the first time range associated with first schedule user interface object  832  is for a relatively short period of time (i.e., seven days versus 30 days), first schedule user interface object  832  provides for multiple blood pressure measurements per day. At  FIG. 8J , first schedule user interface object  832  includes measurement indicators  836  representing time periods (e.g., intervals) within the first time range for respective blood pressure measurements. In other words, measurement indicators  836  indicate various sub-ranges of time (e.g., a half of a day or 12 hours) within the first time range that computer system  600  is configured to prompt the user to provide (e.g., input and/or otherwise transmit) a blood pressure measurement to computer system  600 . 
     In addition, computer system  600  displays add measurement user interface object  838  on blood pressure user interface  800 . In response to detecting user input corresponding to selection of add measurement user interface object  838 , computer system  600  displays measurement input user interface  854 , as shown at  FIG. 8O . As set forth in detail below with reference to  FIG. 8O , a blood pressure measurement received by computer system  600  via measurement input user interface  854  corresponds to a respective measurement indicator  836  that is associated with a current day and/or a current time of day. In other words, in response to detecting user input corresponding to selection of add measurement user interface object  838 , computer system  600  is configured to receive and record a blood pressure measurement that corresponds to the respective measurement indicator  836  associated with the current day and/or the current time of day without receiving and recording a blood pressure measurements that corresponds to a measurement indicator  836  that is not associated with the current day and/or the current time of day. 
     As set forth above, in response to detecting user input  850   h  corresponding to selection of second time range user interface object  822   b , computer system  600  displays blood pressure user interface  800  having second schedule user interface object  834 , as shown at  FIG. 8K . Second schedule user interface object  834  corresponds to the schedule being over the second time range of 30 days. Accordingly, second schedule user interface object  834  includes day indicators  834   a - 834   g  corresponding to respective days of a week for five weeks (e.g., rows within second schedule user interface object  834 ) that occur over the course of 30 days. In contrast to first schedule user interface object  832 , second schedule user interface object  834  does not include interval indicators. Because the second time range associated with second schedule user interface object  834  is for a relatively long period of time (i.e., 30 days versus seven days), second schedule user interface object  834  provides for a single blood pressure measurement per day. In other words, because the second time range includes several weeks, the schedule for recording blood pressure measurements receives a sufficient amount of data to identify trends and/or patterns in the user&#39;s blood pressure even when the data is entered and/or received once per day. 
     At  FIG. 8K , second schedule user interface object  834  includes measurement indicators  840  representing each day within the second time range for respective blood pressure measurements. In other words, measurement indicators  840  indicate various sub-ranges of time (e.g., a single day or 24 hours) within the second time range that computer system  600  is configured to prompt the user to provide (e.g., input and/or otherwise transmit) a blood pressure measurement to computer system  600 . 
     At  FIG. 8K , computer system  600  detects user input  850   m  (e.g., a tap gesture) corresponding to selection of add measurement user interface object  838 . In response to detecting user input  850   m , computer system  600  displays measurement input user interface  854 , as shown at  FIG. 8O . As set forth in detail below with reference to  FIG. 8O , a blood pressure measurement received by computer system  600  via measurement input user interface  854  corresponds to a respective measurement indicator  840  that is associated with a current day and/or a current time of day. In other words, in response to detecting user input corresponding to selection of add measurement user interface object  838 , computer system  600  is configured to receive and record a blood pressure measurement that corresponds to the respective measurement indicator  840  associated with the current day and/or the current time of day without recording a blood pressure measurement that corresponds to a measurement indicator  840  that is not associated with the current day and/or the current time of day. 
     Turning now to  FIG. 8L , computer system  600  displays notification  842  on user interface  844  (e.g., a lock screen user interface and/or a home screen user interface) on a second date (e.g., Friday, May 15th) after the first date. Notification  842  corresponds to a confirmation that a blood pressure measurement was received within a time period of the first time range and/or the second time range corresponding to the current day and/or the current time of day. For example, notification  842  provides a confirmation to the user that a blood pressure measurement was received for the morning of Friday, May 15th when the time range is the first time range (e.g., seven days) and/or that the blood pressure measurement was received for the day of Friday, May 15th when the time range is the second time range (e.g., 30 days). In some embodiments, computer system  600  displays notification  842  after receiving a blood pressure measurement (e.g., via user input while computer system  600  displays measurement input user interface  854 ). In some embodiments, computer system  600  displays notification  842  in response to receiving a blood pressure measurement from an external device (e.g., a blood pressure measurement device configured to transmit a wireless signal indicative of the blood pressure measurement to computer system  600  via Bluetooth, Wi-Fi, and/or Zigbee). In some embodiments, computer system  600  displays notification  842  in response to receiving any blood pressure measurement before computer system  600  displays a reminder notification (e.g., notification  846  at  FIG. 8M ) prompting the user to provide a blood pressure measurement for the period of time within the first time range and/or the second time range corresponding to the current day and/or current time of day. 
     Computer system  600  is configured to prompt the user to provide a blood pressure measurement for the period of time within the first time range and/or the second time range corresponding to the current day and/or current time of day in response to detecting that a blood pressure measurement has not been received. At  FIG. 8M , computer system  600  displays notification  846  on user interface  844  on the second date in response to detecting that a blood pressure measurement has not been received within a threshold time (e.g., 1 hour, 6 hours, 8 hours, 10 hours, 12 hours) from the beginning of the period of time (e.g., 12 am of a day and/or 12 pm of a day) of the first time range and/or the second time range corresponding to the current day and/or the current time of day. Accordingly, computer system  600  prompts and/or reminds the user to provide the blood pressure measurement so that computer system  600  can receive a blood pressure measurement for each period of time within the first range and/or the second time range. 
     In some embodiments, in response to receiving a blood pressure measurement (e.g., via an external device, such as a Bluetooth enabled blood pressure device and/or sensor), computer system  600  is configured to remove and/or cease displaying notification  846  on user interface  844  and/or from another user interface associated with the health application. Accordingly, computer system  600  clears reminder notifications when the reminder to provide a blood pressure measurement is no longer appropriate. 
     At  FIG. 8M , computer system  600  detects user input  850   n  (e.g., a long press gesture) corresponding to notification  846 . In response to detecting user input  850   n , computer system  600  displays skip blood pressure measurement user interface object  848  and log blood pressure measurement user interface object  852  on user interface  844  on the second date, as shown at  FIG. 8N . In response to receiving user input corresponding to selection of skip blood pressure measurement user interface object  848 , computer system  600  clears and/or removes notification  846  from user interface  844 . In some embodiments, computer system  600  provides an additional notification reminding user to provide a blood pressure measurement after a predetermined period of time from detecting user input corresponding to selection of skip blood pressure measurement user interface object  848 . 
     At  FIG. 8N , computer system  600  detects user input  850   o  (e.g., a tap gesture) corresponding to selection of log blood pressure measurement user interface object  852 . In response to detecting user input  850   o , computer system  600  displays measurement input user interface  854  on the second date, as shown at  FIG. 8O . As set forth above, computer system  600  can also display measurement input user interface  854  in response to user input  850   l  and/or  850   m.    
     Measurement input user interface  854  includes first measurement user interface object  854   a  and second measurement user interface object  854   b . At  FIG. 8O , computer system  600  detects user input  850   p  (e.g., a tap gesture) corresponding to selection of first measurement user interface object  854   a . In addition, computer system  600  detects one or more user inputs (e.g., via a keyboard and/or other input device) that correspond to a numeric value of a first measurement of blood pressure, such as a systolic pressure from a blood pressure measurement. At  FIG. 8O , computer system  600  also detects user input  850   q  (e.g., a tap gesture) corresponding to selection of second measurement user interface object  854   b . In addition, computer system  600  detects one or more user inputs (e.g., via a keyboard and/or other input device) that correspond to a numeric value of a second measurement of blood pressure, such as a diastolic pressure from a blood pressure measurement. In some embodiments, measurement input user interface  854  includes a single measurement user interface object that enables a user to input both portions (e.g., systolic and diastolic pressure) of a blood pressure measurement. 
     At  FIG. 8O , measurement input user interface  854  is displayed at 9:41 PM on May 15th (e.g., the current day). As such, inputs corresponding to the first measurement user interface object  854   a  and the second measurement user interface object  854   b  (e.g., collectively a blood pressure measurement) correspond to a respective measurement indicator  836  and/or  840  for the evening of and/or the entire day of Friday, May 15th. At  FIG. 8O , measurement input user interface  854  does not include a user interface object that enables computer system  600  to receive a measurement corresponding to another measurement indicator that is not associated with the current day and/or the current time of day. 
     In some embodiments, computer system  624 , which is in communication with computer system  600  (e.g., and associated with the same user as computer system  600 ), is also configured to provide notifications related to the schedule for collecting blood pressure measurements. For instance, at  FIG. 8P , computer system  624  displays notification user interface  856 . Computer system  624  displays notification user interface  856  in response to a determination that computer system  600  has not received a blood pressure measurement for the period of time within the first time range and/or the second time range. In some embodiments, computer system  624  displays notification user interface  856  when computer system  600  displays notification  846 . 
     At  FIG. 8P , notification user interface  856  includes first measurement user interface object  856   a  and second measurement user interface object  856   b . At  FIG. 8P , computer system  624  detects user input  850   r  (e.g., a tap gesture) corresponding to selection of first measurement user interface object  856   a . In addition, computer system  624  detects one or more user inputs (e.g., via a keyboard and/or another input device) that correspond to a numeric value of a first measurement of blood pressure, such as a systolic pressure from a blood pressure measurement. At  FIG. 8P , computer system  624  also detects user input  850   s  (e.g., a tap gesture) corresponding to selection of second measurement user interface object  856   b . In addition, computer system  624  detects one or more user inputs (e.g., via a keyboard and/or another input device) that correspond to a numeric value of a second measurement of blood pressure, such as a diastolic pressure from a blood pressure measurement. In some embodiments, notification user interface  856  includes a single measurement user interface object that enables a user to input both portions (e.g., systolic and diastolic pressure) of a blood pressure measurement. 
     At  FIG. 8P , notification user interface  856  is displayed at 9:41 PM on May 15th (e.g., the current day). As such, inputs corresponding to the first measurement user interface object  856   a  and the second measurement user interface object  856   b  (e.g., collectively a blood pressure measurement) correspond to a respective measurement indicator  836  and/or  840  for the evening of and/or the entire day of Friday, May 15th. At  FIG. 8P , measurement input user interface  856  does not include a user interface object that enables computer system  624  to receive a measurement corresponding to another measurement indicator that is not associated with the current day and/or the current time of day. 
     In response to receiving a blood pressure measurement via measurement input user interface  854  and/or notification user interface  856 , computer system  600  updates a respective measurement indicator  836  and/or  840  to reflect that the blood pressure measurement is received, as shown at  FIG. 8Q . At  FIG. 8Q , computer system  600  displays blood pressure user interface  800 , which includes second schedule user interface object  834  corresponding to the second time range. In response to receiving the blood pressure measurement for the second date (e.g., Friday, May 15th), computer system  600  updates an appearance of measurement indicator  840   a  (e.g., fills measurement indicator  840   a  with a check mark) corresponding to the second date (e.g., Friday, May 15th) to indicate that computer system  600  received the blood pressure measurement corresponding to the time period associated with measurement indicator  840   a . In addition, computer system  600  updates blood pressure graphical element  802  to include an indication (e.g., a pair of data points) corresponding to the received blood pressure measurement for the second date. In some embodiments, computer system  600  ceases to display add measurement user interface object  838  and/or adjusts an appearance of add measurement user interface object  838  to further indicate that a blood pressure measurement has been received for the current time period associated with the current day and/or the current time of day. 
     At  FIG. 8Q , computer system  600  has also updated the appearance of measurement indicators  840   b ,  840   d , and  840   e  indicating that computer system  600  also received the blood pressure measurements for the days associated with measurement indicators  840   b ,  840   d , and  840   e . In addition, computer system  600  has not updated the appearance of measurement indicator  840   c , corresponding to Tuesday, May 12th, indicating that computer system  600  did not receive a blood pressure measurement for that day that is within the second range. 
     In some embodiments, computer system  600  is configured to receive blood pressure measurements for days and/or other periods of time (e.g., half of days) that occur outside of the current period of time (e.g., the current day and/or the current time of day). At  FIG. 8Q , computer system  800  receives user input  850   t  corresponding to add data user interface object  858  of blood pressure user interface  800 . In response to detecting user input  850   t , computer system  600  displays previous measurement input user interface  860 , as shown at  FIG. 8R . Previous measurement input user interface  860  is similar to measurement input user interface  854 , but also includes date user interface object  860   a  and time user interface object  860   b . In response to detecting one or more user inputs corresponding to date user interface object  860   a , computer system  600  is configured to update a date indicator  860   c  displayed in date user interface object  860   a . Date indicator  860   c  corresponds to a date on which an input blood pressure measurement was taken (e.g., a blood pressure measurement that is input via first measurement user interface object  854   a  and second measurement user interface object  854   b ). Similarly, in response to detecting one or more user inputs corresponding to time user interface object  860   b , computer system  600  is configured to update a time indicator  860   d  displayed in time user interface object  860   b . Time indicator  860   d  corresponds to a time on the date associated with date indicator  860   c  at which the input blood pressure measurement taken (e.g., the blood pressure measurement that is input via first measurement user interface object  854   a  and second measurement user interface object  854   b ). As such, in some embodiments, computer system  600  is configured to receive blood pressure measurements that are associated with a day and/or a time that is prior to or before a current day (e.g., a period of time within the first time range and/or the second time range that is not associated with the current day and/or the current time of day). 
     Turning now to  FIG. 8S , computer system  600  displays blood pressure user interface  800  having second schedule user interface object  834  corresponding to the second time range on a third date (e.g., Tuesday, June 9th). At  FIG. 8S , computer system  600  has updated each of measurement indicators  840  of second schedule user interface object  834 , thereby indicating that a blood pressure measurement has been received for each period of time (e.g., each day) of the second time range (e.g., 30 days). In other words, at  FIG. 8S , computer system  600  displays blood pressure user interface  800  having second schedule user interface  834  after completion of the second time range (e.g., 30 days has elapsed from the time the schedule for collecting blood pressure measurements was initiated). In response to detecting completion of the second time range, computer system  600  further displays share user interface object  862  and new schedule user interface object  864 . Therefore, in some embodiments, computer system  600  forgoes display of share user interface object  862  and/or new schedule user interface object  864  until the second time range (and/or another selected time range) has elapsed. 
     Share user interface object  862  enables the received blood pressure measurements during the second time range to be shared with an external device. For example, in response to user input corresponding to selection of share user interface object  862 , computer system  600  generates an exportable file that includes the received blood pressure measurements during the second time range. Accordingly, computer system  600  can transmit the exportable file to an external device via electronic mail, via short messaging service, via Bluetooth, via Wi-Fi, via short range communication, and/or via another suitable communication technique. 
     New schedule user interface object  864  enables computer system  600  to begin a new schedule for collecting blood pressure measurements. For example, in response to detecting user input corresponding to selection of new schedule user interface object  864 , computer system  600  displays first set-up user interface  818  and/or third set-up user interface  822 . As such, computer system  600  is configured to receive one or more inputs that cause computer system to activate and/or initiate another schedule for collecting blood pressure measurements. 
     As set forth above, computer system  600  is configured to generate hypertension notifications in response to a determination that a set of notification criteria (e.g., hypertension notification criteria) has been satisfied. At  FIG. 8T , computer system  600  displays notification  628  on user interface  630  (e.g., a lock screen user interface and/or a home screen user interface). At  FIG. 8T , computer system  600  detects user input  850   u  (e.g., a long press gesture) on notification  628 . In response to detecting user input  850   u , computer system  600  displays new schedule user interface object  866  and/or skip schedule user interface object  868  on user interface  630 , as shown at  FIG. 8U . Accordingly, computer system  600  can activate and/or initiate a new schedule for collecting blood pressure measurements in response to user input  850   u  on notification  628  and an additional user input corresponding to selection of new schedule user interface object  866 . Therefore, a user can cause computer system  600  to activate and/or initiate the schedule for collecting blood pressure measurements after computer system  600  generates a hypertension notification. In contrast, in response to detecting user input corresponding to skip schedule user interface object  868 , computer system  600  clears and/or removes notification  628  from user interface  630 . 
       FIG. 9  is a flow diagram illustrating a method for managing health information over a predefined time range using an electronic device in accordance with some embodiments. Method  900  is performed at a device (e.g.,  100 ,  300 ,  500 ,  600 , and/or  624 ) with a display generation component and one or more input devices. 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 information over a predefined time range. The method reduces the cognitive burden on a user for tracking and/or monitoring health information, thereby creating a more efficient human-machine interface. For battery-operated computing devices, enabling a user to track and/or monitor health information faster and more efficiently conserves power and increases the time between battery charges. 
     Computer system (e.g.,  100 ,  300 ,  500 ,  600 , and/or  624 ) (e.g., an electronic device; a smart device, such as a smart watch or a smart phone; a mobile device; a wearable device) is in communication with a display generation component (e.g.,  602  and/or  654 ) (e.g., a display, such as a touchscreen display) and one or more input devices (e.g.,  602  and/or  654 ) (e.g., a keyboard, a mouse, a touch-sensitive surface). 
     Computer system receives ( 902 ), via the one or more input devices (e.g.,  602  and/or  654 ), a first set of one or more inputs (e.g.,  850   a ,  850   c ,  850   d ,  850   e ,  850   f ,  850   g ,  850   h ,  850   i ,  850   j , and/or  850   k ) (e.g., one or more taps, gestures, mouse clicks) that includes a first input (e.g.,  850   f  and/or  850   h ) selecting a time range (e.g., the selection of a user-interactive graphical user interface object that corresponds to a first time range from among a plurality of user-interactive graphical user interface objects corresponding to different time ranges; the entry of values corresponding to a time range). 
     In response to receiving the first set of one or more inputs, computer system displays ( 904 ), via the display generation component (e.g.,  602  and/or  654 ), a first user interface (e.g.,  800 ) (e.g., a user interface including data and/or information associated with recorded measurements of a user characteristic (e.g., blood pressure)). 
     In accordance with a determination that the first user input (e.g.,  850   f ) corresponds to selection of a first time range (e.g., a week; two weeks; a month), the first user interface (e.g.,  800 ) includes ( 906 ) a first plurality of measurement indicators (e.g.,  836 ) (e.g.,  14  measurement indicators) within the first time range. 
     In accordance with a determination that the first user input (e.g.,  850   h ) corresponds to selection of a second time range (e.g., a week; two weeks; a month), different from the first time range, the first user interface (e.g.,  800 ) includes ( 908 ) a second plurality of measurement indicators (e.g.,  840 ) (e.g.,  30  measurement indicators) within the second time range. In some embodiments, the first time range is a subset of the second time range (e.g., the first time range is a first week of the month and the second time range is the entire month). 
     The first user interface (e.g.,  800 ) also includes ( 910 ) a first measurement entry user-interactive graphical user interface object (e.g.,  838 ) (e.g., an add measurement affordance corresponding to a respective measurement indicator based on the first user input) that, when selected via the one or more input devices (e.g.,  602 ) (e.g., via a tap gesture on a touch-sensitive surface), initiates a measurement-entry process (e.g., displaying a second user interface that includes one or more user-interactive graphical user interface objects enabling a user to enter a blood pressure measurement). 
     In accordance with the first user interface (e.g.,  800 ) including the first plurality of measurement indicators (e.g.,  836 ) within the first time range, the measurement entry process includes ( 912 ) computer system entering a blood pressure measurement (e.g., a systolic and/or diastolic measurement value) that corresponds to the first time range and a current day (e.g., the current day and/or the current time of day when the first measurement entry user-interactive graphical user interface object is selected). In some embodiments, the blood pressure measurement corresponds to the first time and range and corresponds to a specific measurement indicator in the first plurality of measurement indicators (e.g., a specific measurement indicator in the first plurality of measurement indicators corresponding to a current day and/or a current time of day). 
     In accordance with the first user interface (e.g.,  800 ) including the second plurality of measurement indicators (e.g.,  840 ) within the second time range, the measurement entry process includes ( 914 ) computer system entering a blood pressure measurement that corresponds to the second time range and the current day (e.g., the current day and/or the current time of day when the first measurement entry user-interactive graphical user interface object is selected). In some embodiments, the blood pressure measurement corresponds to the second time range and corresponds to a specific measurement indicator in the second plurality of measurement indicators (e.g., a specific measurement indicator in the second plurality of measurement indicators corresponding to a current day and/or a current time of day). 
     Displaying a user interface that includes either a first plurality of measurement indicators or a second plurality of measurement indicators depending on a selected time range provides the user with control over contents of the user interface that is used for subsequent inputs relating to blood pressure measurements, thereby improving the user-system interaction. Improving the user-system interaction enhances the operability of the computer system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the system by enabling the user to use the computer system more quickly and efficiently. 
     In some embodiments, the first plurality of measurement indicators (e.g.,  836 ) (e.g., 14) includes a first number of measurement indicators and the second plurality of measurement indicators (e.g.,  840 ) includes a second number of measurement indicators (e.g., 30), different from the first number. In some embodiments, the first plurality of measurement indicators includes multiple indicators for a single, first day and the second plurality of measurement indicators includes a single indicator for the single, first day. 
     Displaying a different number of measurement indicators depending on a selected time range provides the user with control over contents of the user interface that is used for subsequent inputs relating to blood pressure measurements, thereby improving the user-system interaction. Improving the user-system interaction enhances the operability of the computer system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the system by enabling the user to use the computer system more quickly and efficiently. 
     In some embodiments, the computer system is in communication with one or more blood pressure sensors (e.g., integrated sensors; sensors of an external blood pressure measurement device that are in wireless communication with the computer system). Computer system receives (e.g., wirelessly), via the one or more blood pressure sensors, first data corresponding to a first blood pressure measurement, wherein the first data is not received in response to user input (e.g., any user input) at the computer system (e.g., the first data is automatically received). 
     In some embodiments, the first data is received while a first notification (e.g.,  846 ) is active (e.g., flagged for display in a notification center; marked as unread; is actively displayed on a display of the computer system). In response to receiving the first data, computer system deactivates the first notification (e.g.,  846 ) (e.g., ceases to display the displayed notification; marking the notification as read; de-flagging the notification). 
     Automatically deactivating a notification when the first data is received assists the user with the management of notifications. Performing an operation automatically enhances the operability of the computer system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the system by enabling the user to use the computer system more quickly and efficiently. 
     In some embodiments, in response to receiving the first data, computer system displays, via the display generation component (e.g.,  602 ), an indication (e.g.,  842 ) (e.g., a notification) that the first data was received. In some embodiments, the notification includes an indication of a time period of the current day that the first data has been associated with (e.g., the entire day, the morning, the evening). 
     Displaying an indication in response to receiving the first data provides the user with feedback as to the data that was received. Providing improved user feedback enhances the operability of the computer system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the system by enabling the user to use the computer system more quickly and efficiently. 
     In some embodiments, the first plurality of measurement indicators (e.g.,  836 ) includes a first measurement indicator that represents (e.g., corresponds to) a first time period (e.g., 12 hours) and the second plurality of measurement indicators (e.g.,  840 ) includes a second measurement indicator (e.g.,  840   a ,  840   b ,  840   c ,  840   d , and/or  840   e ) that represents (e.g., corresponds to) a second time period (e.g., 1 day), different from the first time period. 
     In some embodiments, the first set of one or more inputs (e.g.,  850   a ,  850   c ,  850   d ,  850   e ,  850   f ,  850   g ,  850   h ,  850   i ,  850   j , and/or  850   k ) includes a first input (e.g.,  850   f  and/or  850   h ) (e.g., a tap gesture; a mouse click) corresponding to a first user-selectable graphical user interface object (e.g.,  822   a ) that corresponds to the first time range or to a second user-selectable graphical user interface object (e.g.,  822   b ) that corresponds to the second time range. In some embodiments, the first and second user-selectable graphical user interface objects are displayed on the same user interface. 
     Providing selectable graphical user interface objects for selecting a time range provides the user with feedback as to whether the first or second plurality of measurement indicators will be displayed in response to the input. Providing improved user feedback enhances the operability of the computer system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the system by enabling the user to use the computer system more quickly and efficiently. 
     In some embodiments, after computer system receives the first set of one or more inputs (e.g.,  850   a ,  850   c ,  850   d ,  850   e ,  850   f ,  850   g ,  850   h ,  850   i ,  850   j , and/or  850   k ) (e.g., after displaying the first user interface) and in accordance with a determination that predetermined period of time (e.g., 1 minute; 5 minutes; 30 minutes, 60 minutes; 12 hours; 24 hours) has elapsed (e.g., has passed) since a first event (e.g., since a last blood pressure measurement was received; since a first time (e.g., since 8 AM; since 5 PM); since the first set of one or more inputs were received) without having received (e.g., automatically received; manually received) a blood pressure measurement, computer system displays, via the display generation component (e.g.,  602  and/or  654 ), a reminder notification (e.g.,  846  and/or  856 ) (e.g., a notification that indicates that a blood pressure measurement has not been received). 
     Automatically displaying a reminder notification when certain conditions are met performs the function without requiring further user input and provides the user with feedback about the condition being met. Performing an operation automatically and providing improved feedback enhances the operability of the computer system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the system by enabling the user to use the computer system more quickly and efficiently. 
     In some embodiments, in accordance with the first user interface (e.g.,  800 ) including the first plurality of measurement indicators (e.g.,  836 ) within the first time range and after (e.g., in response to) computer system enters a blood pressure measurement that corresponds to the first time range, computer system modifies the appearance (e.g., marking as completed; changing a color; changing a shape) of a first measurement indicator (e.g., an indicator that corresponds to the first half of the current day) of the first plurality of measurement indicators (e.g.,  836 ). In accordance with the first user interface (e.g.,  800 ) including the second plurality of measurement indicators (e.g.,  840 ) within the second time range and after (e.g., in response to) computer system enters a blood pressure measurement that corresponds to the second time range, computer system modifies the appearance of a second measurement indicator (e.g.,  840   a ) (e.g., an indicator that corresponds to the entirety of the current day) of the second plurality of measurement indicators (e.g.,  840 ). 
     Modifying the appearance of a respective measurement indicator in response to receiving a blood pressure measurement provides the user with feedback as to which indicator the measurement has been associated with. Providing improved feedback enhances the operability of the computer system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the system by enabling the user to use the computer system more quickly and efficiently. 
     In some embodiments, the first user interface (e.g.,  800 ) includes a graphical depiction (e.g.,  802 ) (e.g., a graph (e.g., a line graph; a scatter plot graph); a table) of one or more received blood pressure measurements. 
     Displaying a graphical depiction of received measurement data provides the user with feedback as blood pressure measurements that have been received. Providing improved feedback enhances the operability of the computer system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the system by enabling the user to use the computer system more quickly and efficiently. 
     In some embodiments, the first user interface (e.g.,  800 ) includes a third user-selectable graphical object (e.g.,  803 ) that, when selected, causes display (e.g., in the first user interface) of information (e.g., a scale; a standard shown in the depiction) corresponding to the graphical depiction (e.g.,  802 ) (e.g., to a parameter or aspect of the depiction). 
     Displaying information regarding the graphical depiction provides the user with feedback as to an aspect of the graphical depiction and of the blood measurements depicted in the depiction. Providing improved feedback enhances the operability of the computer system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the system by enabling the user to use the computer system more quickly and efficiently. 
     In some embodiments, the first user interface (e.g.,  800 ) includes a fourth user-selectable graphical object (e.g.,  858 ) that, when selected, causes computer system to initiate a process (e.g., displaying a second user interface that includes one or more user-interactive graphical user interface objects enabling a user to enter a blood pressure measurement) for receiving (e.g., via manual entry) a blood pressure measurement (e.g., a systolic and/or diastolic measurement value) for a time period of a day that precedes the current day (e.g., a past day). 
     Providing an object for entering measurements for previous time periods provides the user with additional control options, thereby promoting improved and sustained user-system interactions. Improving and sustaining user-system interactions enhances the operability of the computer system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the system by enabling the user to use the computer system more quickly and efficiently. 
     In some embodiments the first user interface (e.g.,  800 ) includes a fifth user-selectable graphical object (e.g.,  862 ) that, when selected, causes computer system to initiate a process for transmitting data corresponding to one or more received blood pressure measurements to an external electronic device (e.g., a computer associated with a medical provider). 
     In some embodiments, the first user interface (e.g.,  800 ) includes a sixth user-selectable graphical object (e.g.,  864 ) (e.g., a new journal period affordance) that, when selected, causes computer system to initiate a process for selecting a second time range (e.g., the selection of a user-interactive graphical user interface object that corresponds to a first time range from among a plurality of user-interactive graphical user interface objects corresponding to different time ranges; the entry of values corresponding to a time range) and for displaying a second user interface (e.g.,  800 ) (e.g., that includes one or more features of the first user interface) that includes a third plurality of measurement indicators (e.g.,  836  and/or  840 ) that includes a number of measurement indicators selected based on the second time range. In some embodiments, the sixth affordance is included (only included; first included) in the first user interface in accordance with a determination that a sufficient number (e.g., 14; 30) of blood pressure measurements have been received and/or a determination that a predetermined period of time (e.g., 7 days; 30 days) has elapsed. 
     Providing an object for initiating a process to select a new time range provides the user with additional control options, thereby promoting improved and sustained user-system interactions. Improving and sustaining user-system interactions enhances the operability of the computer system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the system by enabling the user to use the computer system more quickly and efficiently. 
     In some embodiments, the computer system is in communication with one or more sensors (e.g.,  618 ,  620 , and/or  622 ) (e.g., a photoplethysmogram sensor, a gyro sensor, and/or an electrocardiogram sensor). In some embodiments, the one or more sensors do not include a sensor for directly and/or specifically measuring a pressure value of a user of the computer system. Computer system receives ( 702 ) first sensor data associated with a user of the computer system from the one or more sensors (e.g.,  618 ,  620 , and/or  622 ) (e.g., periodically and/or intermittently receiving measurement data from the one or more sensors, where the data from the one or more sensors includes data indicative of light absorption of skin of a user associated with the computer system (e.g., one or more measurements received from a photoplethysmogram sensor), data indicative of orientation and/or angular velocity of the computer system (e.g., one or more measurements received from a gyro sensor), and/or data indicative of voltage over time (e.g., one or more measurements of electrical activity of the heart received from an electrocardiogram sensor)). In some embodiments, the first sensor data from the one or more sensors does not include a direct measurement of pressure (e.g., a value from a sensor that is configured to specifically measure pressure, such as a manometer, a pressure transducer, a strain gauge, and/or a piezometer). In some embodiments, the data from the one or more sensors is data from (e.g., generated by; relating to; about) a user of the computer system. In some embodiments, the data from the one or more sensors includes an indirect measurement of pressure. For instance, raw data from the one or more sensors may be utilized (e.g., as seeds of an algorithm) to calculate and/or estimate pressure, such as systolic blood pressure and/or diastolic blood pressure. In some embodiments, the computer system does not use the data to indirectly determine and/or calculate a numerical measurement of pressure. 
     In response to receiving the first sensor data from the one or more sensors ( 704 ) (e.g.,  618 ,  620 , and/or  622 ) and in accordance with a determination that the first sensor data from the one or more sensors (e.g.,  618 ,  620 , and/or  622 ) satisfies a set of hypertension notification criteria (e.g., the computer system uses the data from the one or more sensors to make an assessment as to whether the user associated with the computer system is at risk for chronic hypertension (e.g., the user associated with the computer system has consistently high blood pressure as opposed to one instance, one estimation, and/or one measurement of blood pressure that is considered high blood pressure); the computer system uses the data from the one or more sensors to generate a risk score indicative of chronic hypertension and the risk score exceeds a threshold value), computer system displays, via the display generation component (e.g.,  602 ), a notification (e.g.,  628 ) indicative of a hypertension event (e.g., the data from the one or more sensors indicates that the user associated with the computer system is at risk for chronic hypertension as opposed to one instance (e.g., one measurement and/or one estimation) of high blood pressure) associated with the user of the computer system (e.g., the computer system generates a notification that is displayed by the display generation component of the computer system (e.g., a smart watch) and/or the computer system is in communication with an external device (e.g., a smart phone) and generates a signal received by the external device that causes the external device to display a notification on a display generation component of the external device). In some embodiments, the set of hypertension notification criteria do not include a criterion (e.g., do not include any criterion) based on (e.g., that take into account) a blood pressure value (e.g., diastolic and/or systolic value of a user of the computer system). In some embodiments, the set of hypertension notification criteria do not include a criterion (e.g., any criterion) based on a pressure measurement. 
     In response to receiving the first sensor data from the one or more sensors ( 704 ) (e.g.,  618 ,  620 , and/or  622 ) and in accordance with a determination that the first sensor data from the one or more sensors (e.g.,  618 ,  620 , and/or  622 ) does not satisfy the set of hypertension notification criteria (e.g., the computer system uses the data from the one or more sensors to make an assessment as to whether the user associated with the computer system is at risk for chronic hypertension (e.g., the user associated with the computer system does not have consistently high blood pressure); the computer system uses the data from the one or more sensors to generate a risk score indicative of chronic hypertension and the risk score does not exceed the threshold value), computer system forgoes displaying the notification (e.g.,  628 ) of the hypertension event (e.g., a notification is not displayed by the computer system and the external device because the data from the one or more sensors indicates that the user associated with the computer system is not at risk for chronic hypertension). 
     After (e.g., in response to; within a predetermined time of) computer system displays the notification (e.g.,  628 ) of the hypertension event, computer system displays, via a display generation component, a notification (e.g.,  866 ) prompting the user to initiate a process to receive a second set of one or more inputs to select a third time range and for displaying a third user interface (e.g.,  800 ) (e.g., that includes one or more features of the first user interface) that includes a fourth plurality of measurement indicators (e.g.,  836  and/or  840 ) that includes a number of measurement indicators selected based on the third time range. 
     Automatically generating a prompting notification after displaying a notification of a hypertension event surfaces to the user a relevant function, without requiring further user input and therefore improves and sustains user-system interactions. Performing an operation automatically and sustaining the user-system interaction enhances the operability of the computer system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the system by enabling the user to use the computer system more quickly and efficiently. 
     Note that details of the processes described above with respect to method  900  (e.g.,  FIG. 9 ) are also applicable in an analogous manner to the methods described above. 
     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 provide users with an indication of one or more health parameters and/or one or more health events. 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, twitter IDs, home addresses, data or records relating to a user&#39;s health or level of fitness (e.g., vital signs measurements, medication information, exercise information), date of birth, or any other identifying or personal 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 facilitate a third party assess a health of the user. Further, other uses for personal information data that benefit the user are also contemplated by the present disclosure. For instance, health and fitness data may be used to provide insights into a user&#39;s general wellness, or may be used as positive feedback to individuals using technology to pursue wellness goals. 
     The present disclosure 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. Such policies should be easily accessible by users, and should be updated as the collection and/or use of data changes. 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/sharing should occur after receiving the informed consent of the users. Additionally, such entities should consider taking 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. In addition, policies and practices should be adapted for the particular types of personal information data being collected and/or accessed and adapted to applicable laws and standards, including jurisdiction-specific considerations. For instance, in the US, collection of or access to certain health data may be governed by federal and/or state laws, such as the Health Insurance Portability and Accountability Act (HIPAA); whereas health data in other countries may be subject to other regulations and policies and should be handled accordingly. Hence different privacy practices should be maintained for different personal data types in each country. 
     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 hypertension notifications, 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 or anytime thereafter. In another example, users can select not to provide blood pressure data. In addition to providing “opt in” and “opt out” options, the present disclosure contemplates providing notifications relating to the access or use of personal information. For instance, a user may be notified upon downloading an app that their personal information data will be accessed and then reminded again just before personal information data is accessed by the app. 
     Moreover, it is the intent of the present disclosure that personal information data should be managed and handled in a way to minimize risks of unintentional or unauthorized access or use. Risk can be minimized by limiting the collection of data and deleting data once it is no longer needed. In addition, and when applicable, including in certain health related applications, data de-identification can be used to protect a user&#39;s privacy. De-identification may be facilitated, when appropriate, by removing specific identifiers (e.g., date of birth, etc.), controlling the amount or specificity of data stored (e.g., collecting location data a city level rather than at an address level), controlling how data is stored (e.g., aggregating data across users), and/or other methods. 
     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, captured sensor data and/or received blood pressure data can be maintained entirely on a user&#39;s electronic device and access to the data corresponding to the captures sensor data and/or received blood pressure data by another device (e.g., a server) can be prohibited without the user&#39;s express consent.
