Walk up! Alarm Clock
A drastic option for heavy sleepers, this iOS app has an alarm that can be silenced only one way: by taking your smartphone for a stroll. The free cheat-proof app can't be muted, shaken or shut off.
Designed to wake users peacefully, ZenAwake's alarm plays low-frequency sound waves that "relax and focus your mind." The iOS app, $2.99, also displays a daily inspirational quote that users can share via Facebook or Twitter.
There's nothing more motivating than a good public shaming. That's the concept behind this accountability app--free for iOS and Android--that humiliates users by posting to Facebook when they snooze through their alarm. Embarrassing? Sure. But so is oversleeping.
