HeartScan is intended for wellness and educational purposes. It provides high-precision pulse measurement but is not a replacement for professional medical diagnosis.
Placing the phone on your chest allows the motion sensors to capture the mechanical oscillations (seismocardiogram) generated by your heart's contraction and valve movements.
The app has direct access to high-frequency sensor data and native processing, which can provide more stable and detailed waveforms than browser-based measurements.
