Continuous monitoring devices like the BioButton can measure heart function with FDA-approved EKG, providing data comparable to clinical use.

“Well, so instead of going to your doctor once a year for an annual checkup, this thing's monitoring my body 1,000 times a second for vibration. It can hear how I speak, how I cough, it's looking at my movements, how I sleep during the day, how I move. But most importantly, for this device, it's measuring my heart in many different ways. It's actually an FDA approved EKG, this is something that you have to put stickers all over your body, the doctor used to measure it, sine waves and whatever, you can now do it with your wristwatch, though that's not FDA approved. This one is the real deal. Doctors use this information to diagnose patients.”
