Cronosurf Wave is a chronograph watch app for Android devices and a watchface for Wear OS! No other OS are supported for now. SOME UNSUPPORTED operating systems include: Tizen (Samsung GEAR and GALAXY 3 and earlier), Garmin, HarmonyOS (like Huawei Watch GT2).
If you have a Galaxy Watch 4, please install from Google Play directly on the watch.
This app is based on the original design started 2014 as a web-based technology demonstrator (cronosurf.com). Its main focus lays on design, functionality and usability. It has become the most popular chronograph watch face for Wear OS. If you are a chronograph watch lover, you'll find yourself using Cronosurf as your day-to-day app for alarm, countdown timer and stopwatch.
Since Cronosurf has many features, the app includes a comprehensive user manual. The Button Assistant (also available on the web version) labels each button according to the momentary state of the watch and helps you to quickly get familiarized with the basics. To activate it, simply tap on the area above the watch.
Discover all the special features and great usability of Cronosurf Wave. You will love it!
Cronosurf Wave also runs on Wear OS watches without the need of an Android device! Install it directly from Google Play on the watch.
Standalone Android smartwatches are also supported. Note that Cronosurf runs as a regular app on these devices (not as a native watchface).
