LieQ - Real Lie Detector

Real PPG Lie Detector — Analyze heart rate changes in real-time

LieQ is the world's first lie detector app that uses real PPG (photoplethysmography) heart rate measurement. Place your finger on the rear camera, ask a question, and watch the heartbeat change in real-time.

▸ HOW IT WORKS

Your body reacts when you lie. Heart rate increases, HRV changes — LieQ catches these micro-changes through 4 steps:

1. Flash illuminates your fingertip
2. Camera reads blood flow changes
3. Lying → Sympathetic nervous system activation
4. HRV fluctuation is detected and scored
