Ratings and reviews

Kinda works, but it's overly basic. You can't set different interval groups or time changes.

Seems like one of the best option for a CPR timer for Wear OS 3 at the moment. Simple and seems to do what it says. No extra useless fluff, I like that. I would like to see an infinite repeat (sections) option, the ability to rename the 2 timers and to have it display the current time on the watch app while running. I like the audible and haptic alarms and the 2 timers having different colours. Can't comment yet on battery consumption, will update when I have more info on that.

Very close to 5 stars. It would be perfect (when it is running on the watch), if the "start" moment could be started immediatelly by the double-pinch gesture (without 5 seconds beeping) or, at least, the timer could optionally start right after the application is launched. Thank you for your good work.
