myAchy llc has Cleu Alarm (iTunes Link) for the iPhone and iPod Touch in the iTunes App Store for FREE (regularly 99-cents) for a limited time. This deal expires June 14, 2012.
With Cleu Alarm, you “connect-the-dots” to disarm the alarm. It’s challenging enough to help you wake up with a familiar gesture.
Cleu Alarm, unlike majority of alarm clocks on the App Store, works just fine if you keep your device on silent/vibrate mode, both, while in the app or with a locked screen.
Cleu Alarm’s wake screen is ambidextrous so you’re not swiping your phone out of your hand when you shut off the alarm.
