Not really sure what this app is tracking but the cycles seem accurate. I like it!

Paid money for this thing but will not save sleep data, wasted a week of using this app trying different settings but will not save. All it says is "are u sure want to quit" tried forums and contacting zen labs but no response,

This is a very good app. I had these Garman for years but this is really good. I will continue to use this other than Garman.
