Join Cardiogram to analyze your heart rate, ECG, and activity data from Apple Watch, Fitbit, Garmin, and WearOS watches. Monitor your cardiovascular health and fitness.
Cardiogram analyzes your heart rate, ECG, and activity data from Apple Watch, Fitbit, Garmin, and Wear OS smartwatches to help you monitor your cardiovascular health. Join millions of others who have uncovered new heart rate conditions like atrial fibrillation and sleep apnea, caught a medical emergency, adjusted treatment plans, and improved fitness.
Answer questions like:
•What triggers my AFib or other arrhythmia episodes?
•How frequently does my heart rate spike during sleep?
•What daily habits help improve my POTS symptoms?
•How has my heart rate recovery improved with this workout routine?
The iPhone app is compatible with Apple Watch, Fitbit, Garmin, and Wear OS by Google devices. The Cardiogram app for Apple Watch shows you a graph of your heart rate in real time, on your wrist.
In the phone app:
• The Timeline visualizes your heart rate each day with interactive heart rate and ECG graphs. Use it to spot trends and irregularities. When you see an unexpected change, add a note with symptoms and potential causes.
• Metrics shows you how your resting heart rate, sleep, and move, exercise, and stand activity rings are trending over time.
• Habits lets you discover a new healthy habit and invite friends to join you and build accountability.
• You can also build a profile to share health data with medical researchers and contribute to studies on abnormal heart rhythms like atrial fibrillation, heart failure, and more. Note: Cardiogram is not a medical device and is currently for research purposes only.
For Apple Watch users, Cardiogram displays data from the Health app, including heart rate, ECG, sleep, steps, and Apple Watch activity rings, in chart or graph format. For Fitbit, Garmin, and Wear OS by Google devices, Cardiogram receives data directly from the respective manufacturer.
Cardiogram is compatible with many devices with a heart rate sensor, including all Apple Watch models, Fitbit (Charge, Versa, Ionic, Alta HR, Inspire HR, and more) Garmin (fēnix, Forerunner, and Vívo series, and more), and wear OS by Google (Fossil, Ticwatch, Moto, LG, Misfit, Huawei, and more).
Best of all, these core features are free!

Ratings and Reviews
My husband had purchased this app & had been using it for a few months after he suffered a PE. He recovered well, but wanted to have a way to analyze the data from his Apple Watch in order to monitor his heart health. Well, a few days ago, his tooth became infected which resulted in a root canal, then the next morning he felt horrid, he opened the app to see that his resting BPM was 178 and he hadn’t done anything. his heart was in AFIB, so I called the nurse practitioner on the back of our health card who directed him to go to ER Immediately! Sure enough his heart was in AFIB and they took care of him there. It was a scary situation, but glad we had the app to clearly display his heart activity, and now takes his heart health more seriously. When you can actually see what your heart is doing, it makes you want to implement healthier lifestyle choices. I also like that the app lets you share your information with anyone you choose. You can printed it out for your doctor also.

Hi Emma's Mom! I was going through our older reviews and just wanted to thank you for taking the time to share this story with us. We're always trying to improve the app for our users and it's amazing to hear about times when Cardiogram has really helped. If you have any thoughts about how we can improve the app, please feel free to reach out to me directly at email@example.com, I'd love to hear them. I hope that both of you are doing well and staying safe! ^Linda
Premium has a serious glitch(s)
The big advantage of the premium cardiogram app subscription is the ability of the app to alert you to elevated heart rate and low heart rates that could be indicative of a heart problem. You adjust the settings for high and low bpm. The default high heart rate setting is 129 beats per minute. The problem I have encountered numerous times since I started my subscription is that I get high heart rate notifications from cardiogram while I am working out in cardio sessions. These alerts come even though I have opened and am using my exercise app on Apple Watch 4 which syncs to cardiogram. Cardiogram app recognizes that I am in a workout as when I finish my workout by selecting end workout I get a nice workout display on the cardiogram app. I shouldn’t be receiving high heart rate alerts during a workout as I am trying to reach my target heart rate which is almost 150 bpm. Cardiogram premium should have different high heart rate alert settings: one for during workouts which for me might be 160 bpm and another for when I am not exercising which would be a lot lower. I agree I can change the settings before and after each exercise period but who will remember to do this and for the price of this app this should have been thought through.
Also at first I believed the premium app said they would respond to comments submitted thru the app in 24 hours. Now it says 4 business days. I sent an inquiry almost a week ago and have not had a response.

This is very helpful feedback, we're really sorry for not responding to your email. I've notified the team and we're working on a fix. We'd love to get more detail on the issue though—could you email me at firstname.lastname@example.org?
Isuues and no help
So I had issues. Like I asked for them NOT to use my main EMAIL as I really don’t like the idea of what if they get hacked into like yahoo and others? I’d rather they used my throwaway Facebook account for me to use as a sign in and them to know my FB password as I really don’t care so much about it as I do my email account. I’ve emailed about it more than once and no one bothered to email back.
I had issues with my graphs not populating.... except for the Steps. But I have a Fitbit so that’s redundant. The main thing I wanted it for was to watch my heart and so far, it’s done a spectacularly crappy job at that. It doesn’t tell me a rhythm, only a high, doesn’t tell me a low. I’m trying to see what value it has OVER the HealthKit heart rate
I finally uninstalled it. Thanks for nothing guys. You were singularly unhelpful.
Update: Cardiogram support eventually got back to me and they reset my account. For those who have yet to open a Cardiogram account here is my advice. Make a throwaway email account to attach it to. Because they were nosy post on other formats. What business is it of theirs who my “friends” are? Oh and they’ll “ask permission before they post on your account”. Uh, I don’t want to take the time to say no. So upgrading from a 1 although I’m not sure how much more helpful it is than HealthKit truly. I have yet to see a aha moment

Hi Swetiepeti! I was going through our old reviews and just wanted to follow up on this. I thought you might be interested to know that last year, we made it possible for users to use Cardiogram without creating an account so users don't need to share their email if they don't want to.
I'm sorry to hear that it took such a long time for you to get a response to your concerns. We've made a lot of improvements to our support processes, so if you ever decide to give Cardiogram another try, we're here for you!
We've also added additional features (e.g., we do now show a low!) that will (hopefully) provide more value to our users, such as a journal section to track notes and symptoms, and multiple export formats for our Premium users.
In any event, thank you for being one of our earlier users and for taking the time to update your review! I hope all is well and that you're staying safe. If you have any thoughts or concerns, please feel to reach out to me directly at email@example.com. Take care! ^Linda
