Designing a great app requires a focused approach. Interactions with Apple Watch are measured in seconds, so your app must quickly provide the user with essential information. Three primary themes define the design approach to take.
Glanceable apps make the most important information readily available to the user. Interactions occur over short periods of time, so apps must convey the most important information up front and communicate that information clearly and without distraction. Being glanceable also means keeping the app’s snapshot up-to-date so that the Dock is always displaying current information. A glanceable app provides a complication to give user information directly from the watch face, and it uses a custom notification interface to maximize the scan-ability of notification content.
