iPhone/alarm clock app.

Anyways, it's really hard for me to wake up in the mornings to go to school. I bought a few alarms on my iPhone but, none of them are good because you have to keep them on for the night and you can't multitask. Mostly half the time the alarm doesn't even work.


So, does anybody know a good alarm clock app where you can multi-task and it doesn't have to be on to work?


Thanks
