If you want to wake up in the morning this is your alarm. Pictures mode (as I call it) is the way to go, but shaking mode (or shake to turn off or whatever) is not bad either - you have to shake it pretty vigorously for the app to register a "shake". I charge my phone while I sleep (as should everyone for a number of reasons...) so I havent been effected by that. The app even has some work around a for those of us who might try to "close" the app (double clicking the home button and swiping the app up) - the only way to cheat is to uninstall the app. Something Ive done before....
As for the interface, I like it and think its cute. Its an alarm app and you arent really gonna spend much time adjusting it and such so for when you do set it I dont mind a unique way to do so.
