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.
