Profile

We've built HeartScan.app, a free, browser-based solution that accurately measures your heart rate using only your smartphone's built-in accelerometer—no camera, no wearables, no app installation.Unlike typical camera-based methods (photoplethysmography/PPG), HeartScan leverages seismocardiography (SCG), capturing mechanical vibrations from your heartbeat through your phone's sensors. With a neural network trained on over 500,000 user-contributed records, we've reached over 95% accuracy for cardiac phase (R-peak) detection, achieving medical-grade BPM estimation directly in your browser.It's entirely frictionless: no login, ads, or paywalls.
