Been using this for years. Suddenly in the last couple of weeks, the sleep hours count has gone from generally too high to way too low. It must have autoupdated? I cleared cache and data, no change, reinstalled, no change. Have now updated to 4.26.32 and we'll see. I've had none of the problems others have. Tracks my sleep and nighttime awakenings very well. I always leave the phone on charge, and where I put it points the mic directly at me. Always set a 2nd alarm if it's critical.

it is a good app. the only thing is that it doesn't see if you are still asleep even after your alarm goes off to wake you up. I have had it a few times now where I wake up from the alarm, turn it off and go back to sleep. it doesn't spot i am still sleeping therefore doesn't track it through my watch. if a feature could be added where it can tell through your watch if you are asleep or not would be super useful. I have also had it where I forget to turn the alarm on before bed.

I would really appreciate it if there was an option of an easy wake up but instead of setting a time of day, setting it to amount of hours asleep. I often struggle with falling asleep and it would help if I say wanted a 30 min nap or a full 8 hrs or other. And to know the alarm wasn't going to go off just as I was nodding off. Thanks! (I do often find the app has minimised and is somehow running in the background for days whilst not showing up and the 'using mic' warning light not on)
