*Note: This app is meant for entertainment purposes only. The thumb print scan is only a simulation, and is not meant to be used as a replacement for a real polygraph test. Lie Detector is a prank fingerprint scan app that tries to determine if you are telling the truth or a lie based on your thumbprint scan. Meant for entertainment purposes only. Your phone can not actually read your fingerprint or tell if you are lying or not. But it's a great gag for parties or for impressing the ladies at the club! Lie Detector also contains some neat customization options. You can adjust the speed of the scan simulation, and you can set your own custom response, so that you can play the ultimate prank on your friends and family! There are also various themes to choose from, so you can adjust the look of the app to match your personality!
