The app is developed by Paolo85 and falls under the subcategory of entertainment. The app is not to be taken seriously as it is just an entertaining prank to be used with friends and family.

The app is simple to use, just place your finger on the fingerprint scanner and wait for the app to verify your age. It is a fun way to pass the time with friends and see who gets the most accurate (or ridiculous) results. The app is not meant to provide accurate age results and is purely for entertainment purposes only.
