Good idea, but needs work

I like the idea behind this app, but it has failed to wake me up several times. Instead of playing an alarm, the app just repeatedly makes notifications (which I barely hear) until you unlock the phone and open the app. *Then* the alarm starts going off. Whats the point of that? Like I said, its a good idea, but I dont think this app is worth buying.
