This app is wonderful when it works. I wake up feeling refreshed! I didnt realize that in addition to getting enough hours of sleep, I also needed to wake up in the right part of my sleep cycle. Unfortunately, after this last update, the app quits in the middle of the night and doesnt wake me up or track any of my sleep. Also, I was very disappointed to find that I paid for the app a very long time ago and recently they added a subscription fee and locked features that I paid to unlocked. Very disappointing! I will be looking into a different sleep cycle app.
