Age Detector Prank Scanner is a free high-tech fingerprint scanner which tries to discover your age by scanning your thumbprint. Just put your thumb on the scanning pad, wait while it scans and calculates how old you are, and see what the app thinks your age is!
The app does not actually scan anything and is for entertainment purposes only. Your phone screen does not have that feature. However, It's nevertheless a great gag application for get togethers or parties or for impressing the ladies or fooling your friends.
