Animated laser sweeps, concentric radar rings, and dynamic fake telemetry readouts build the tension.

The phone owner's hidden outcome control is completely invisible on the scanning screen, so every prank lands.
Deep Scan Mode
A 10-second theatrical analysis with expanded diagnostic readouts for maximum suspense.
Viral Result Cards
Every scan generates a branded result card with the verdict, question, and timestamp — share to WhatsApp, Instagram, TikTok, or Messenger in one tap.

100% Offline, Zero Accounts
No internet connection or account needed for the core prank game — play anywhere, anytime.
Entertainment Only — Not a Real Polygraph
Prank Lie Detector is a novelty prank game. It is NOT a real lie detector or polygraph — no biometric data is captured or analyzed, and all verdicts are random or owner-selected via Prankster Mode.
