Hexawatch - Watch Face is a free Android app developed by Nilhcem that offers a unique and stylish way to tell time on your smartwatch. The app features a hexagonal clock face with 12 triangles around the outside that indicate the hours in the same position as a conventional clock. Additionally, the six large triangles at each side of the inner hexagon indicate the first digit of the minutes (0X, 1X, 2X, 3X, 4X, 5X), while the digit displayed at the center of the hexagon is the last digit of the minutes (0 to 9).

One of the best things about Hexawatch is that it is battery-friendly and respects your privacy by not requiring any permissions or tracking. The app also helps preserve your watch screen by preventing burn-in and supporting ambient and low-bit mode. The circular and square layouts make it easy to use on any smartwatch, and the app's source code is available on Github. To change the theme colors, simply select Hexawatch from the Android Wear app on your phone and click on the cog-wheel to launch the settings screen.
