About Cardiogram: Wear OS, Fitbit, Garmin, Android Wear

Note: we currently only offer the app in English. We're working to support more languages soon!

Your heart beats over 102,000 times per day—Cardiogram tells you what that data means. We help you understand health, sleep, stress, and fitness through simple, but powerful charts that show the impact of day-to-day activities on your heart health.

The Cardiogram app for Android phones is compatible with Wear OS by Google (formerly Android Wear), Fitbit, and Garmin watches with a heart rate sensor. The Cardiogram Wear OS app on your watch works even if you use an iPhone.

Timeline
A digital diary of your heart rate data. Monitor how your heart rate changes minute-to-minute, with a detailed, expanded view for workouts. Annotate any section of your heart rate data to clarify what may have caused a spike or dip, like stress (e.g. a meeting with your boss), diet, medication, caffeine, or exercise. Compare with past days and search through all your labeled data. Swipe to see a leaderboard of steps with your friends, regardless of what device they have. You can invite friends who own an Apple Watch, Fitbit, Garmin, or even those who don't own a wearable device or pedometer at all. Leaderboards are also compatible with the built-in Google Fit step tracker on your phone.

Metrics
Compare your resting heart rate, steps, and sleep to other Cardiogram users, and track your improvements over time. The Metrics pane is an easy way to spot trends, see what’s working, what isn’t, and keep yourself on track.

Care
After you provide basic health information, we’ll use this in conjunction with your heart rate data to help identify patterns and insights relating to your cardiovascular health. We may offer follow-up tests, like an A1C blood test, home sleep test, mobile ECG/EKG, or bluetooth-connected blood pressure cuff.

You can also help others and contribute to medical research. Share your health data with leading medical professionals and researchers, like the Health eHeart study conducted by the University of California - San Francisco.

Habits
Find a new healthy habit or activity you'll love. Commit to building streaks and join tens of thousands of others who are working to improve in the same way. Optimize your overall health, sleep, stress, fitness, and lifestyle. Invite your friends to build accountability. Take control of your goals, whether it’s to lose weight or dropping your time at the track.

Sleep tracking note
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.

WearOS watch app
For Wear OS devices, Cardiogram monitors your heart rate at a customizable frequency—you can adjust this frequency directly from the Cardiogram app on your watch. You can also initiate Workout Mode from your watch, which records your heart rate continuously.

Other
Our app does not have built-in ECG / EKG functionality and does not measure individual heartbeats.
