The Lie Detector Simulator is a game created to have some innocent fun and simulates a fingerprint scanner for detecting lies. You can prank and make fun of your friends, kids or others by getting them to think you can detect if they are lying to you. Preset answers (truth or lie) in the settings menu and then ask them questions. Have them place their finger on the fingerprint scanner while answering the questions. The app will display the preset answers.

If you choose to play for fun, just cancel all the settings and the app will respond randomly, alternating between truth and lie.

Disclaimer: This app is just a prank, a fun game and it is not a real lie detector (polygraph) nor a real fingerprint scanner.
