Cronosurf Wave Pro watch

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 OS include: Tizen (Samsung GEAR, GALAXY 3 and earlier), Garmin, HarmonyOS (like Huawei Watch GT2).
Galaxy Watch4: 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. 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 is now integrated in the app (portrait mode). Use it to quickly getting familiarized with the basics. To activate it, tap on the area above the watch.

Cronosurf Wave runs on Wear OS watches and without the need of an Android device! Install it directly from Google Play on the watch.

Pay only once! If Google Play wants to charge again when installing on Wear OS, please wait a few hours until the servers sync the first purchase.

Optional ``Android Smartwatch Mode`` for standalone Android watches (like the Finow X5) to optimize the app for the watch screen. (Cronosurf runs as an app on these devices, not as a native watchface).
