Android: Any alarm can wake you up. Mimicker, a free alarm app for Android from the Microsoft Garage, can help make sure you stay awake. If you're the type to hit the snooze button in the morning without even thinking about it, Mimicker can help. In order to dismiss an alarm, you have to perform a series of actions called Mimics. Right now, there are three types of Mimics. Colour Capture makes you take a picture of an item of a certain colour, Express Yourself asks you to make a facial expression and Tongue Twister gets you to repeat a phrase. Mimics are also timed, so if you don't complete one, the alarm will ring again.
