Cardiogram measures your heart rate once every two minutes, so that you can how daily activities like coffee, walking, stress, and eating drive your heart. Your most recent heart rate is a glance away on your watch, and the Cardiogram app shows you a chart of your heart rate for the whole week.

Know your metrics by heart

Your resting heart rate is a key indicator of your overall cardiac health—Cardiogram lets you track how it's changing day-to-day.

Works with Google Fit

Activities from Google Fit, like biking or walking, are automatically shown in Cardiogram.

Fight heart disease

Could data from your watch be the key to saving lives? We're working with researchers at the UCSF Health eHeart study to develop algorithms to detect and treat heart disease, and you may be invited to participate in special research studies.

Easy on your watch's battery

Beta testers report that Cardiogram consumes just 1-3% of your watch's battery—for the whole day.
