I-Digit Watch Face is a free watch face and clock widget for Android's Wear OS. It is a personalization app by thema that allows users to customize their watch face with different design colors, day and month, watch battery, mobile battery, and weather.

The app's settings are located in the "Wear OS" app of your mobile, where you can choose design colors on both watch and mobile, define heartbeat frequency refresh rate, weather refresh rate, weather unit, 12/24 hours mode, interactive mode duration, and more.

I-Digit Watch Face also offers premium settings like switching between eco/simple b&w/full ambient mode, choosing background among different styles, blending background with colors, defining a secondary timezone for digital display, and much more.

Overall, I-Digit Watch Face is a great option for those looking to customize their Wear OS watch face and clock widget. However, it is not compatible with Samsung Gear S2/S3 running Tizen OS.
