Limitation makes it only a novelty item – The Rock Clock™ Review

The app is, by its very nature, hilarious. However, I don't understand why the phone has to stay on and unlocked for it to work. No other alarm app I've used has this limitation. Because of this, you have to sleep next to a glowing phone. That or cover it with something, which would seem to lessen the effect of the alarm. Unfortunate.
