Cardiogram: Heart Rate, Pulse, BPM Monitor

Offers in-app purchases

Requires: Wear OS, Fitbit, and Garmin smartwatches with a heart rate sensor. English-only for now, but we'll be adding more languages soon.

Your heart beats over 102,000 times per day—Cardiogram is a heart rate journal that helps you uncover what that data means. Understand your health, sleep, stress, and fitness through interactive charts and comprehensive notes that help track day-to-day fluctuations in your heart health.

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

• A digital diary of your heart rate data. Monitor how your heart rate changes with interactive, minute-to-minute graphs.
• See all of your data points, not just summaries, and get separate, zoomed-in views for workouts.
• Help you and your doctor track your cardiovascular health in detail with symptom and mood logging and freehand notes.
• Highlight and annotate any section of your heart rate data to clarify what may have caused a spike or dip, like stress, diet, or medications.
• 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.

• Compare your resting heart rate, steps, and sleep to other Cardiogram users.
• View your long-term trends to see how building new habits helps improve your daily metrics.

• 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.

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