Free Retina Scanner Android App & Review

Retina Scanner helps to increase your phone's security in a cool and funny way. Set the unlock requirements and then make your friends look mystified by holding your phone close to your face for a requisite amount of time to see whether your phone is getting unlocked or not. After you set the unlock requirements, just play a prank on your friends by allowing them to unlock your phone using their eye. When you forgot the settings just keep holding the home button to exit.
