Cronosurf Wave Pro watch

Cronosurf Wave Pro is a chronograph watch app for Android devices and a watchface for Wear OS watches. No other OS are supported for now. Note: Due to latest Google policies allowing only WFF watch faces on the Play Store (from 2026 on), we had to remove the Wear OS version from this release. Previously installed watch faces will continue to function. 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. Optional "Android Smartwatch Mode" for standalone Android watches (Cronosurf runs as an app on these devices, not as a native watchface).
