Wear OS 7 also extends the standardization of the system. Workout apps can optionally use the user interface and technology of Google’s system apps so that, for example, heart rate measurement or music playback during a workout works the same, regardless of which app is used. A Gemini API allows third-party apps to be integrated into the AI assistant and the apps to be controlled by voice command.
The music player has new options for streaming audio to multiple devices via Google Cast or Bluetooth. Wear OS 7 should also make it easier to develop watch faces, meaning that the selection could potentially grow. Finally, the operating system receives numerous minor improvements to performance and the user interface.
