Xtimer Clock

App Description
Xtimer — The Alarm That Actually Wakes You Up
Meet the loudest, most fun alarm clock on the App Store. Xtimer stars a 3D rooster who dances on your screen while blasting real animal calls, truck horns, and sirens — sounds you physically cannot sleep through. Alarms ring through your lock screen and silent mode just like the built-in Clock app, with vibration synced to every blast.
