About Complications
Complications are small elements that appear on the watch face and provide quick access to frequently used data. Users can customize most watch faces and install the complications that they want to see. The system provides built-in complications for weather information, upcoming calendar events, the user’s activity, and many more types of data. Apps can also add support for complications and display app-specific data.
