An electronic device with a display and a touch-sensitive surface displays a user interface of an application. The device detects a first portion of an input including a contact on the touch-sensitive surface, and then detects a second portion of the input including movement of the contact across the touch-sensitive surface. The device displays, during the movement, application views including an application view that corresponds to the user interface of the application and another application view that corresponds to a different user interface of a different application. The device then detects a third portion of the input, including a liftoff of the contact from the touch-sensitive surface. In response, the device, upon determining that application-switcher-display criteria are met, displays an application-switcher user interface, and upon determining that home-display criteria are met, the device displays a home screen user interface that includes application launch icons.
