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

This is a cool app but it has problems. I use it in tandem with my Fitbit tracker. The main problem is that Fitbit's sensors are notoriously inaccurate and consequently Cardiogram uses this bad data to assess your health. Often times when I'm exercising my Fitbit sensors just don't work that well. You have to time the end of your exercise sessions almost impossibly precisely to get a good assessment. Very healthy guy, yet my health score was all over the place simply due to this technical error.
Disappointing. After finally finding a compatible app for my Samsung galaxy 4 watch, I have been unable to sync the data at all from the last few days. After multiple attempts, reinstall and reconnect, I've not yet been able to obtain the data from my watch onto my app.
I like the resolution of the measurements this app takes. However, the UI is very slow to respond, and sometimes the app doesn't load at all. Closing and reopening it works.
In my experience this app is unreliable. Indicates that I was asleep in the afternoon during work for 1hr and 10mins! My job is not that boring! I have uninstalled this app from my phone and watch.
Seems like it has potential, but it's too messy. It didn't automatically add my sleep times at first, that fixed itself but none of my exercises are pulling through. I don't understand the point of integrating with Google Fit if it won't pull the information through. Add the badly designed UI/UX and it was uninstalled in short order
I can't believe the amount of notifications.... if I want to know what the color chart means, I will look it up why would you need to send notifications about such things and all the other non health related things your app notifies us about? Think about things from a consumers point of view, and not a marketers.
I don't have a wearable device at the moment and have been using my pulse meter. I could nit figure out how to manually enter my readings so I deactivated my account. I wouldn't recommend using this unless you have a wearable device.
Worthless on Android. Its worthless and arbitrary in its updates, tells me it will update scores in say 9 days then 2 days later tells me it updated yesterday. No way to update info or conditions and it didn't even allow me to finish filling out my profile. As soon as I clicked POTS it moved on before I could check another box like high blood pressure. Contradicts itself between score and comparisons. Would have canceled sooner if I could figure out how. Not used to managing subs via Google.
Metrics shows I'm doing well and claims I'm better than half the users with the stats provided. Moving over to the report tab, I am appearently in bad health? Yeah, okay; far from it. Not a useful app if its gonna lie. I question about the data it collects as well, always trying to get something from its user. Syncing with connect never happens on its own either. Try for free? Lol, doesn't let you.
Pretty bad app. Draws inference with insufficient or non-existent data and tries to motivate people to pay for a subscription showing garbage reports.
Very Bad and Misguided. From last many days charts are empty, Resting shows 92 on chart without data and in metrics showing 82, Plus sleep shows 0 hours for multiple days even I slept 9 hours. Health index was 3.8 and then suddenly its now 0.2 out of 5. Plus showing 40% chances of hypertension? Seriously?
It has some compatibility issues with Galaxy Watch 4 as mentioned in my previous review. But they did directly activate a refund when Google was stalling, so I wanted to update the review.
Very interesting and useful insights when you leave it collecting your data and come back to take a look in a few weeks. I was shocked to find that my sleeping quality is poor and needs improvement. I'm surely going to work on it!
Love the UI. Information about certain aspects of my health is easy to understand. in future updates, I would like the ability to email my doctor the results that the watch reads specified to the last two weeks for example.
Has the potential to be good, but so many bugs. Keeps throwing in random sleep sections, i delete them all and go back in amd its added a load more, even to previous dates. Shows random spike in heart rate up to 180 when im sat still. Sometime removes tags ive added. And the daily averages dont match the sections, like my sleep average is 10bpm higher than the tagged sleep section. Tells me my sleep bpm is up 40 from previous date when it was actually lower.
great app I use it everyday! keeps up with your low and peak and resting. great to just keep up without having to keep up!
Can't connect to my watch! It's not fit for purpose, this is a basic core requirements, no connection, nothing works! 😡
Or maybe u can add Bluetooth watches and if not, add blackdot ones. Otherwise I have to buy a new watch to use this
Very informative, quite interesting and it seems to work seemlessly with other watch apps.
Occasionally, the free app will not sync from my Garmin fenix5, but overall it records a good analysis of heart health.
Too many probs. Asks irrelevant data. Couldn't talk to Fitbit in iOS (even tho app said it was connected)and kept asking for invasive info (the app does not need access to Fitbit friends. EVER. NOT FOR ANY REASON) Privacy policy v unclear. On Android app help tells me to delete the ios account and log in using Google login. HOW ABOUT NO???!!! I will NEVER use Google login for this. The entire app acts like a data grabber, prob intending to monetarize the data). Deleting. ZERO STARS
Since the last Update the watch app has been weird. The graph is empty, and it always shows "1703m ago" above the measured heartrate. Even if I've just pressed measure. Synching to the phone takes multiple tries, switching Bluetooth off and on, on both devices, a few times. But that might not be an app problem.
