About
Cardiogram was a digital health app that used heart rate and sleep data from wearable devices (Apple Watch, Fitbit, Samsung Galaxy Watch, Pixel Watch) to screen for heart conditions including atrial fibrillation, hypertension, diabetes, and sleep apnea. Powered by deep learning algorithms developed in partnership with UCSF, the app achieved 97% accuracy in detecting AFib. Cardiogram was acquired by ilumivu in 2021 and subsequently shut down in 2025 when its investors sold the company and laid off the team.
