Apps are different from complications or tiles, which are glanceable representations of app content. Apps display more information and support richer interactivity. The user often enters an app from another surface, such as the launcher, recents, a notification, complication, tile, or voice action.\n\nPrinciples\n----------\n\n\n**Focused**\nFocus on critical tasks to help people get things done within seconds. \n\n**Shallow and linear**\nAvoid creating hierarchies deeper than two levels.
