Cronosurf Wave is a chronograph watch app for Android devices and a watchface for Wear OS watches.

NOT FOR SAMSUNG GEAR/GALAXY WATCHES (running on Tizen OS).
We are evaluating the development for Tizen watches. Stay tuned.

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 (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 runs on Wear OS watches with complete functionality and without the need of an Android device!
Note: For touch interactivity, Android 6.+ on the watch is required

Standalone Android smartwatches are also supported. Note that Cronosurf runs as a regular app on these devices (not as a watchface).
