Three types of navigation flow are available to use in your app. The content you are presenting determines the most appropriate flow to use. The three types are:
Use lateral navigation to communicate information across individual screens so users can view them one by one. Navigate screens by swiping right or left or by rotating the bezel. Page indicators show which part of the content is currently being viewed.
Use hierarchical navigation when you cannot display all the content at one level, or when you divide content into primary and secondary information. Avoid too many levels.
Back navigation returns users to the previous screen, allowing users to retrace their steps and determine where they are. Users can backtrack to the previous screen by pressing the Back key.
The Back key returns users to the previous screen, and the Home key takes them to the watch face. If a user is already on the watch face, pressing the Home key takes them to the Apps screen.
