Lie Detector Test - Prank App

Lie Detector Test – Prank App turns your phone into a realistic polygraph simulator. Ask a question, let your friend place a finger on the fingerprint scanner and watch the lie detector "analyze" their heartbeat and body temperature. Five seconds later the whole screen turns green or red: TRUTH or LIE! 😱

It's the funniest lie detector prank for parties, sleepovers, family game night and hanging out with friends.

🔍 HOW THE LIE DETECTOR TEST WORKS
1. Ask your friend a tricky question.
2. They hold a finger on the scanner for 5 seconds.
3. The polygraph scans with sounds and a heartbeat animation.
4. The verdict fills the screen: green for TRUTH, red for LIE.

🤫 SECRET PRANK CONTROL (VOLUME BUTTON TRICK)
Want to decide the result yourself? Before or during the scan, secretly press VOLUME UP for TRUTH or VOLUME DOWN for LIE. Nobody will notice – your friend will think the lie detector really caught them! If you don't press anything, the result is random.
