Waqup

Waqup! (pronounced wake up) Is your social alarm clock.
Set your alarm clock and record a wake up message. Be creative.

With the free version wake up messages will be saved and then sent around randomly. When your alarm sets off you'll receive anybody's recording. Yours will be sent to anybody else. You'll be able to rate wake up calls and choose them as your favorite to wake up to.

With the pro function you can create a friends list and send personal messages to mutual friends. It's also possible to choose your favorite friends to wake you up. Another function you have is to queue other people's wake up calls to friends besides the ones you make yourself.

Log in with facebook and find facebook friends who are using Waqup too.
The ones you don't want to hear in the morning can be blocked and unblocked when you want to.

Slide to end the alarm to the right side, slide left to snooze. Set snooze times to 5 or 10 minutes.
After ending the alarm you can see who's message has played.
