Your app must conform to the font size set by the user in System Settings. If the user selects a larger font size, ensure that text and controls are not cut off by screen edges.

Provide a minimum of 48x48dp touch targets on your app. For more information, see Accessibility on Wear OS.

Allow users to swipe to close from almost all screens. Ongoing fitness activities or panning screens, such as an interactive map view, are exempt from this requirement, but you must provide a clear call to action to close the view. For more information, see Navigation.

When a user has an ongoing activity, you must do the following:

• Show the ongoing activity indicator on the watch face.
• Update recent apps with the appropriate app launcher chip for the ongoing activity.
• Reference the ongoing activity from the tile, if the tile is present in the tile carousel.

For more information, see design guidance about Ongoing activity tiles.

Preserve user or app-state when leaving the foreground and prevent accidental data loss due to back-navigation and other state changes.

When your app is resumed from the launcher or recent app switcher within minutes of last use, then restore the app state as close as possible to its previous state.

In the app launcher, correctly represent the app’s icon and name, consistent with device implementation.

For more information, see Appear in recents and app resume.

If content is scrollable, allow the user to use rotary input to control content. This includes scrolling through an app, scrolling a picker, and controlling volume.

For more information, see Rotary input.

Display the scroll bar when the user enters a scrollable view, and when the user scrolls.

For more information, see Show the scrollbar.

If you include a tile with your app and the user is signed out, prompt the user to sign in when they open the tile.

For more information, see Empty states.

If you include a tile with your app, add a tile preview to help your user see what content is shown in the tile manager on their watch and phone.

Display the time of day clearly at the top of the app home screen and any ongoing activity screens. Screens with full screen continuous content, such as camera view or maps are exempt from this requirement.
