Lie detector- Face Scanner

LIE DETECTOR - FACE SCANNER & VOICE STRESS ANALYZER Think you can spot a liar? Lie Detector uses your phone camera and microphone to scan facial expressions and voice stress in real time. Ask a question, let someone answer, and watch the AI deliver its verdict. The ultimate truth game for parties, family nights, and friend groups. ★ HOW THE LIE DETECTOR WORKS Our face scanner analyzes eye movement, blink rate, head movement, gaze direction, and smile authenticity frame by frame. The voice stress analyzer detects volume variation, hesitation patterns, and vocal trembling. Both signals combine into a lie score from 0 to 100 with a verdict ranging from Definitely Truth to Definitely Lying. Everything runs on your device. No face data, voice recordings, or biometric information is ever uploaded to any server. ★ MULTIPLAYER MODE — ARE THEY LYING? The perfect party lie detector game. One player speaks a question using built-in voice recognition. The question appears on screen. The second player answers while the face scanner and microphone analyze simultaneously. Five seconds of real-time analysis produces an instant verdict. Play up to three rounds per session with a full results breakdown at the end. ★ SOLO MODE — AM I LYING? Challenge yourself with the solo lie detector. Choose from seven question categories and let the app ask questions using text-to-speech in your language.
