Concentric Native Watchface is a free personalization app for WearOS developed by Forestwood Associates. It offers three watch faces in one app, with one having three different styles. The app features large(r) fonts, 2-3 complications on the watch faces, and is always on display friendly, with the ability to adjust watch face, complications, and even the time.

Concentric Native Watchface offers multiple color palettes, pixel-shifting to avoid burn-in during AOD, control over colors and complication elements, and the ability to show AOD in full colors. The app has a 15fps rate for a good battery experience, with a 1fps Low Power mode, and a heart rate complication that uses the built-in Health Services to provide the latest heart rate BPM.

Overall, Concentric Native Watchface is a great choice for those who want a watch face that is customizable, always on display friendly, and offers multiple color palettes. It is a great alternative to the built-in Samsung watch face, with the added benefit of a heart rate complication that can be re-used by any other watch face.
