I bet this could be a great app but is not yet there. I purchased yesterday to give it a try, the hours are not being recorded correctly, the alarm doesn’t work and the app won’t sync to Health. Too bad because the app have a beautiful design but the Quackstro website doesn’t even work. Better stay with Sleep++ which is very simple, doesn’t have a lot of functionalities but works great. Also if you feel you don’t want the app, ask for a refund in iTunes.
