WHY FINGERPRINT LIE DETECTOR PRANK? Most prank apps just show fake notifications. Our lie detector prank uses actual fingerprint sensor interaction, making it far more believable and entertaining. When your friend physically presses their finger to the scanner and sees the polygraph analyzing their "pulse patterns", the reaction is genuine.
Our US users love this app for parties. With 15 languages available, you can prank friends anywhere in the world.
TRUTH OR DARE BONUS: Use our lie detector as a truth or dare companion. Instead of just "truth", use the polygraph test to verify their answers. Did they really tell the truth? The fingerprint scanner will find out!
FOR COUPLES: Ask the questions you have always wanted to ask. Our lie detector prank makes even sensitive questions fun and lighthearted. It is a conversation starter, ice breaker, and entertainment all in one.
ENTERTAINMENT DISCLAIMER: This is a prank and entertainment app. The fingerprint scanner is simulated and does not actually detect lies. The polygraph results are randomly generated for entertainment purposes. Use responsibly and always let people know it is a prank app after the fun!

Comments on Lie Detector Prank - Polygraph for Android
★★★★☆Abigail L· Dec 6, 2023
Surprisingly, I like this app. When I got my heart tempo up it detected I lied, when I slowed it down it worked. Really good for fake scenarios, but definitely didn't work when I lied (I'm a sociopath lol). Only bad thing would have to be the ads, there's one upon opening in popular form, one video form (5-15 seconds) and one or two for the next try.

This app is completely false. Neat gimmick though.
