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
We currently only offer the app in English.

Charged for what was advertised as a free trial and it's already having sync delays. I had the app 20 minutes. Update: Got refunded. So, I uninstalled the app. It was just slow in updating the readings taken with my watch. I don't need this for medical reasons, just for fun, but if I did, reliable readings would be pretty important. Hope you guys can improve.

Thank you for taking some time to leave us a review. This isn't the experience we want a user to go through, if you've never subscribed to Premium before you shouldn't be charged at all. I'm more than happy to look into this and issue a refund if needed. Also, I'm curious to know more about these delays. Can you send a message at hello@cadiogr.am?

I paid for the annual subscription during their flash sale in December. The features lasted maybe a month, then disappeared. I tried to contact their support and have heard nothing back since I sent the request two weeks ago. If you use this app, never upgrade, you won't get any of the extra features they advertise and no one will help if you have issues.

This has been marginally useful in the past but now refuses to sync with my Fitbit Versa 2 despite disconnecting and reconnecting. The app has no trouble-shooting features and there is zero support from the company even if you pay for a subscription. Overall this is a pretty poorly written piece of software. The UI is opaque, once you sign up for Premium there's no way to check on your status, the sync function is very flaky. Overall a great idea with a lot of potential very badly implemented. NOT RECOMMENDED.

Hi Ralph, I'm sorry to hear that you're having difficulty syncing your Fitbit with Cardiogram. I'd be happy to help you troubleshoot - you can reach me at linda@cardiogr.am. If you have a moment, I'd appreciate if you could elaborate on what you mean by the UI being opaque? We're always trying to improve our implementation. Thanks! - Linda
