Fairly crappy app.
It only requires two user actions: start sleep and stop sleep. But has very error prone UI for doing those.
Seems to work somewhat, tho it constantly loses data. Data is there one day, gone the next.
Very frustrating app definitely not worth paying for.
Why is there an (obscure) sync button? Why isnt that automatic?
