I guess it does what it says.
However:
• You need to start up the app every night, no recurring alarms
• it needs to be active the whole night. no locking the phone, no quick email check (what is this, iOS 2?)
• the phone cant be in silent mode. So how should I sleep if every email and text wakes me up? Other apps can play sound while in silent mode (ie navigation)
Thus, the risk is high that you forget one of the steps and then you dont have an alarm. Also:
• no retina graphics
• its too expensive for those shortcomings.
