Speaking of Wear OS, the Xiaomi Mi Watch layers MIUI For Watch on top of Wear OS. It is the first smartwatch to run a custom skin on top of Google’s smartwatch operating system. There are over 40 apps baked into the watch, including lighter versions of popular MIUI apps like Tasks, Recorder, Notes, Mi Home and more. MIUI For Watch also has its own app store which is now accessible to third-party developers.
