TruthScan – Lie Detector

🔍 TruthScan – Lie Detector, Stress Analyzer & Pulse Monitor

TruthScan is an advanced lie detector, truth detector, and behavior analysis app that uses your smartphone's real sensors to detect stress, nervousness, and deception patterns in real time. Works as a polygraph-style stress detector using actual accelerometer, gyroscope, microphone, and touch sensor data.

Now with a built-in heart rate monitor — measure your pulse using just your phone's camera.

Unlike simple prank lie detector apps, TruthScan is based on real signal analysis, combining motion, voice, touch, and heart rate data to reveal subtle changes in human behavior.

❤️ PULSE MONITOR — MEASURE YOUR HEART RATE

Turn your phone camera into a heart rate reader — no extra hardware needed:
- Place your finger over the rear camera lens
- The flash shines through your skin, detecting blood flow
- Get real-time BPM (beats per minute) readings
- Track HRV (heart rate variability) for stress insight
- View MIN, AVG, MAX heart rate over your session
- Live pulse waveform and BPM-over-time chart
- Adjustable sensitivity slider for any phone model

Great for satisfying your curiosity about your resting heart rate, or seeing how your pulse reacts in different moments.

🧠 HOW THE LIE DETECTOR WORKS

TruthScan measures multiple physical signals at the same time:

📱 Motion & Stability Tracking
- Detects micro hand tremors using accelerometer & gyroscope
- Measures physical instability linked to stress responses

👆 Touch Pressure Analysis
- Tracks how steady your finger pressure is
- Detects micro-variations, tension, and instability

🎤 Voice Signal Analysis
- Analyzes voice energy and waveform behavior
- Measures response timing and speech patterns

❤️ Heart Rate Detection
- Camera-based reading of your pulse in real time
- Changes in BPM and HRV are strong indicators of stress
- Inspired by the principles behind classic polygraph testing

⚡ SMART MULTI-SENSOR ANALYSIS

TruthScan combines all 11 signals into a unified system to detect:
- Stress reactions
- Behavioral changes
- Response inconsistency
- Cognitive pressure
- Heart rate elevation

Results are based on deviation from your personal baseline, making analysis adaptive and more accurate.

📊 REAL-TIME RESULTS
- Live behavior score with color-coded gauge
- Reaction spikes detection
- Signal deviation tracking
- Multi-sensor correlation
- Session timeline with audio playback

🎯 USE CASES
- Check your resting heart rate anytime
- See how your pulse changes when calm vs. excited
- Fun lie detector games with friends
- Party truth-or-dare challenges
- Interview preparation and self-awareness
- Conversations and negotiations

⚠️ IMPORTANT DISCLAIMER

TruthScan detects physical and behavioral reactions, not truth itself. It is not a medical device and does not diagnose, treat, or monitor any health condition. Heart rate readings are estimates for general interest only. All results are for entertainment and self-analysis purposes and should not be considered medical advice or factual proof.
