Great idea for an app and, in theory, I know it would do a great job waking me up. There are two problems that I have found with it. The first is that I have noticed that if you push the home button enough times, the alarm will turn off without spinning. The second is that it would be nice if my phone could be on silent overnight and still have the alarm work since I am easily woken up by middle-of-the-night notifications.
