Complications Suite for Wear OS is a powerful tool to personalize your Wear OS smartwatch. It provides the ability to add custom complications to the watch face, including the current date, time, and day of the week. Complications can be set for each day of the week, and will appear when you touch the watch face. It also includes the current date and time, as well as the day of the week, and the current weather.

This app was created to provide the missing custom complications for Wear OS. It will work with all Wear OS watches, including those with the new, full-screen watch face.
