Heart Health Report Card
• Track personalized risk scores to monitor how your heart health is changing over time and how different habits or increased stress are affecting your risk for heart attacks and chronic disease.
• Use Cardiogram’s heart analyzer to compare your pulse rate with past days and search through all your labelled heart health data.
• Scores are generated by our clinically-validated ML algorithm using factors such as age, sex, height/weight, and various pulse rate metrics.

WearOS watch app
• View your instant heart rate or use detailed charts as a pulse and stress monitor.
• Monitor your heart rate variability while working out.

ECG and Sleep Tracking
Our app does not have built-in ECG / EKG functionality and does not measure individual heart rates. We retrieve sleep tracking data directly from the Google Fit, Fitbit, or Garmin Connect apps and show this information in the context of your heart rate. We don’t write any data to Google Fit yet, but stay tuned for updates.

Supported Languages

Ratings and reviews

Worked great year one. Since August 2023, App does not track unless manually pushed to do so and only records for that moment. Customer service tried to help, but un successful. Re-installed, restarted, etc., etc., All settings checked for correctness per cardiogram instructions. All good there. Still no auto record...continuing to have problems w/ app. Despite 2 customer service troubleshoots, still does not record or connect , at best intermiitently. Can not recommend.

I had some issues with data recording at first from my Galaxy watch 4, but I contacted support and they had me change some settings. Now the app seems to work great, I have heart issues on both sides of my family. So, it's nice to see the data. If you're having issues I would contact support and they should be able to help you. They were super nice and I recommend the app

Loved this App at first seemed to work great and i paid for subscription. But recently its been missing alot of data even when google fit has the data missing from cardiogram so its the App not my watch or sensors. For instance during sleeps periods i have large amounts of missing data, even with wearing watch tight. But when i check google fit it has no missing heart data. Great concept but seems not even close to being accurate.
