Alarm Clock 2.4.5 Publisher's Description

Alarm Clock is a menu item alarm clock for setting either one-time alarms or repeating alarms. Then choose anything in the iTunes library to wake to: songs, playlists, even podcasts. The application takes care of the rest, even waking the computer from sleep if needed.

You can configure your snooze duration to the length you want. You can even increase/decrease your snooze time right from the alarm window. Plus, if you have an apple remote, you can even hit snooze without getting out of bed. And if waking up to blaring alarms in the morning isn't your cup of tea, there's an 'easy wake' option which will gradually increase the system volume over time. And even this is configurable for you!
