For when you are exhausted from travelling and need a bigger push to wake-up in the morning.
Alarm clock Wake N Shake has recently updated with a completely redesigned interface to make it minimalist in-line with iOS7, and a pleasure to use and look at… while maintaining its evil, merciless way of waking people up. Animations like a starry night sky fade-in to help users doze off. They also added animated Zzz’s that float away randomly when users take a nap. Other subtleties like having the minutes digits “drain” as seconds go by.
You can’t snooze nor turn down the volume and you must shale your device to turn the alarm off. Likely quite effective as long as you don’t throw your iPhone across the room.
