A computer system displays a first version of a first user interface that includes first user interface objects displayed concurrently with a first background. The first user interface objects include content from a first plurality of applications. In response to detecting a first input, when the first input includes movement in a first direction, the system replaces display of the first version of the first user interface with a second user interface that includes representations of a second plurality of applications. When the first input includes second movement in a second direction, the system replaces display of the first version of the first user interface with display of a second version of the first user interface that includes second user interface objects displayed with a second background. The second user interface objects correspond to a third plurality of applications and include content from the third plurality of applications.
