## What is DeceptionDetection?

Explore your body's signals.

This app uses your device’s camera to estimate heart-related signals (BPM) and visualize how they change during short, guided yes/no prompts. It’s a simple, game-like biofeedback experience designed to help you notice patterns in arousal and relaxation.

Start with three neutral prompts to establish a baseline. Then answer three general prompts to observe how your BPM may shift. The app charts these changes to support awareness and reflection—no interpretations about truthfulness.

Whether you’re sharing a lighthearted session with friends, practicing calm responses, or exploring your own physiology, this app offers a unique way to experience pulse-based biofeedback.

Features
- Real-time heart rate estimation using your device camera
- Baseline calibration followed by gentle “challenge” prompts
- Interactive, session-based biofeedback visuals
- Solo or shared session modes
- No wearables or extra hardware required

Wellness Notice
This app provides wellness biofeedback and does not determine truthfulness. It is not a lie detector, polygraph, or medical device and should not be used for decision-making, diagnosis, or any legal purposes.
