About this app

Discover the truth with Lie Detector: Polygraph AI! Have you ever wondered if someone is being completely honest with you? Put them to the test with the ultimate truth or lie detector test prank!

Our AI-powered voice scanner is an advanced vocal analyzer designed for pure entertainment and fun. Using high-fidelity biometric scanning technology and Machine Learning, our app simulates a professional polygraph experience directly on your smartphone.

🔍 HOW IT WORKS
Our AI engine simulates the analysis of subtle "micro-tremors" and frequency modulations in the human voice. When we are under stress, vocal cords undergo physiological changes. This lie detector simulator captures these patterns in real-time, giving you a fun, detailed report on the probability of truth.

✨ KEY FEATURES

Real-Time Voice Scanner: Watch the live spectrogram as the lie detector captures every nuance of the voice.

AI-Powered Analysis: Advanced algorithms simulate vocal stress patterns to deliver engaging results.

Detailed Reports: Get more than just a "True" or "False". Discover fun labels like "Mild Stress" or "High Veracity".

Secure History: Save your funniest prank sessions in a private history log.

Premium Design: Cyber-Tech interface with haptic feedback (vibrations) and immersive polygraph sound effects.

🎮 PERFECT FOR:

Having fun with friends and family playing truth or dare.

Pranking your partner or colleagues with a funny lie detector test.

Adding a professional "tech" touch to your social gatherings.

🔒 PRIVACY & SECURITY
Your privacy is our priority. All voice processing is done locally on your device. We never record, store, or transmit your audio data to any external server.
