I need an alarm that shuts off automatically

i have an ipod so an app would be good, but i cant find an app that doenst have a snooze button:(

Alright, I finally found an app that makes a sound and i dont have to press any button to turn it off.
The default sounds in it are too long and will completely wake me up, or force me to move and turn it off.
It also supports the default ipod push sound, but this is a little too easy to ignore.
So I now need a sound that is good in this situation. does anyone have this, or knows where I can find this? :cheeky:

This is for a FILD by the way.

Well, I've got a really good one for your computer.
This is the one I use, it's perfect for me. Alarm Clock by Tarry 91
Set it to play an audio file, and set it to not repeat. It can do multiple alarms as well.
