A method, comprising: at a wearable electronic device with a touch-sensitive display, wherein the touch-sensitive display comprises one or more sensors to detect the intensity of contacts with the touch-sensitive display: detecting a first contact on the touch-sensitive display at a position corresponding to an icon for launching a first application on the wearable electronic device, the first contact having a first maximum intensity; in response to a determination that the first maximum intensity is below a threshold intensity: launching a first application; detecting a second contact on the touch-sensitive display while the first application is displayed in the foreground of the touch-sensitive display, the second contact having a second maximum intensity; and in response to detecting the second contact on the touch-sensitive display while the first application is displayed in the foreground of the touch-sensitive display: in accordance with a determination that the second maximum intensity is above the threshold intensity: initiating a first process for sending an instruction, via wireless communication, to an external device, wherein the instruction causes the external device to display an affordance for launching a second application on the external device corresponding to the first application, wherein the instruction comprises an indication of a state of the first application, for invoking the state in the second application when the second application is launched.; and in accordance with a determination that the second maximum intensity is below the threshold intensity: initiating a second process other than for sending the instruction to the external device, wherein the state of the first application corresponds to one of: a user interface screen of the first application, a position in a navigation hierarchy of the first application, a location in a document displayed in the first application, and identifying whether a feature of the first application is active. detecting a first contact on the touch-sensitive display at a position corresponding to an icon for launching a first application on the wearable electronic device, the first contact having a first maximum intensity; in response to a determination that the first maximum intensity is below a threshold intensity: launching a first application; detecting a second contact on the touch-sensitive display while the first application is displayed in the foreground of the touch-sensitive display, the second contact having a second maximum intensity; and in response to detecting the second contact on the touch-sensitive display while the first application is displayed in the foreground of the touch-sensitive display: in accordance with a determination that the second maximum intensity is above the threshold intensity: initiating a first process for sending an instruction, via wireless communication, to an external device, wherein the instruction causes the external device to display an affordance for launching a second application on the external device corresponding to the first application, wherein the instruction comprises an indication of a state of the first application, for invoking the state in the second application when the second application is launched.; and in accordance with a determination that the second maximum intensity is below the threshold intensity: initiating a second process other than for sending the instruction to the external device, in accordance with a determination that the second maximum intensity is above the threshold intensity: initiating a first process for sending an instruction, via wireless communication, to an external device, wherein the instruction causes the external device to display an affordance for launching a second application on the external device corresponding to the first application, wherein the instruction comprises an indication of a state of the first application, for invoking the state in the second application when the second application is launched.; and in accordance with a determination that the second maximum intensity is below the threshold intensity: initiating a second process other than for sending the instruction to the external device, a user interface screen of the first application, a position in a navigation hierarchy of the first application, a location in a document displayed in the first application, and identifying whether a feature of the first application is active.
