About this app
*Note: This app is meant for entertainment purposes only. The thumb print scan is only a simulation, and it does not actually have the ability to tell if you have been naughty or nice! Will Santa be bringing you presents or coal this year? Have you been naughty or nice? There is only one to find out! Naughty or Nice is a novelty prank thumb print scanner app that tries to determine if you have been naughty or nice based on a mock fingerprint scan. Simply place your thumb on the scanner and the app will tell you if you have been naughty or nice! Great app for Christmas parties or for the kids! Naughty or Nice also contains a couple of customization options. You can adjust the speed of the scan simulation, and you can even set your own custom response, so that you can play the ultimate prank on your friends and family!
