BabyBlue

BabyBlue is a terrifying app where you can use your smartphone to call evil Baby Blue, one of the most terrifying creatures in the world of urban legends: the motherless blue baby ghost.

Calling Baby Blue is actually pretty simple, since all you need is your Android and a bathroom. To call Baby Blue, lock yourself in the bathroom and turn off the lights so that the only source of light is your smartphone screen. Place your arms so it looks like you're cradling a baby and say 'Baby Blue' three times in front of the mirror. If you do it correctly, you'll start to feel a cold hand scratching at your face. To get rid of Baby Blue, all you have to do is separate your arms and turn on the lights.

BabyBlue not only provides you with the perfect dim lighting but also has a button to help you keep track of how many times you've said 'Baby Blue,' as well as subtle sound effects that create a scary atmosphere. This app is great for nights when you want to give yourself goosebumps.
