Wear OS 7 is the latest version of Google's smartwatch operating system, focusing on improved power efficiency and a more expressive user interface. It introduces Material 3 Expressive, a design refresh with visual and motion components for personalization. Key features include seamless authentication with Credential Manager and support for watch face marketplaces via Watch Face Push. Developers are encouraged to adopt Compose for Wear OS, a modern UI toolkit, for building apps

Google announced new features for Wear OS 7 Google I/O 2025 today, giving the operating system a design makeover with Material 3 Expressive, the design language the company unveiled earlier this month.

Google released the developer preview of Wear OS 6, which is based on Android 16, for testing on Tuesday.

With Wear OS 6, Google is trying to make apps look more cohesive, so app tiles will adopt the default system font. Plus, the dynamic theming library will adjust your app or tile’s color to match the color scheme of the watch face on Pixel Watches.

The core promise of the new design reference platform is to let developers build better customization in apps along with seamless transitions. The company is releasing a design guideline for developers along with Figma design files.

In addition, Google is releasing The Wear Compose Material 3 and brand-new Wear ProtoLayout libraries for developers with extended color schemes, typography, and shapes for more dynamic-looking apps.
