Bad app needs work

On consecutive nights I toggle to sleep mode as I'm going to bed. When I wake up in the morning I toggle sleep off. When I check the dats on my phone it indicates her I slept 15 hours and has changed my pm sleep time to am. That makes it useless. Also, there is no way to edit the times from the phone app. This would be helpful.



I paid five dollars for an app that crashes every time I open it. Only once did it work and it didn't even record my sleep. I want my money back.


Doesnt work

Tried 3 consecutive nights, all it did was drain my watch battery. Doesn't record anything. Unacceptable garbage for a 5$ app.
