## Description

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:

01. Flash illuminates your fingertip
02. Camera reads blood flow changes
03. Lying → Sympathetic nervous system activation
04. HRV fluctuation is detected and scored

▸ REAL MEASUREMENT, NOT FAKE

• Real-time PPG waveform display
• RMSSD / SDNN / HR weighted HRV scoring
• Based on Scientific Reports 2024 methodology
• Patent Pending — 3 patents filed

▸ 97+ QUESTIONS

• 40 General questions — fun party questions
• 57 Adult questions — couples & party mode
• Write your own custom questions
• Random pick button for each category

▸ IMPORTANT NOTE

LieQ is an entertainment app. For ages 16+.

Patent Pending · Based on Scientific Reports 2024
