About this app

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 changes in Google policies, the Galaxy Watch 7, Galaxy Ultra and Pixel Watch 3 are not supported. You can install it 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).

Thanks for your 5-star review!! Due to new Google policies, all new watches delivered with Wear OS 5+ now ONLY support faces made with the Watch Face Format, which doesn't allow for code. Without code, it is technically impossible to recreate our interactive watchfaces. We recommend to contact Google so they see the need for legacy format faces.

It looks like an awesome watch face. Too bad it can't be installed on a Samsung Galaxy Watch7. I would have thought Samsung was a pretty big company, worth supporting; apparently not. Maybe one day. If so, I'll be first in line.

Due to new Google policies, the Galaxy Ultra/Watch7 and Pixel Watch 3 now ONLY support faces made with the new Watch Face Format. To redevelop our faces with WFF is practically impossible, since it only supports XML-tags and no code. We recommend you contact Google so they see the need for legacy format faces. Your Cronosurf team.

I have a China made watch which is as fully functional as an android or apple. Chronos is completely incompatible with Kospet watches. I down loaded Chronos anyway. As an all it works just fine on my Kospet. Reports of its incompatibility were exaggerated. A few settings adjustments and it works fine and is very cool
