About this app

Cardiogram: Heart IQ is a heart rate monitor and symptom tracker that helps you detect and manage health conditions like POTS or atrial fibrillation, using minute-by-minute heart rate information collected by your smartwatch. We provide a health report card score that is updated weekly and risk scores for hypertension, sleep apnea, and diabetes so you can follow your progress for preventing or managing these conditions. Interactive, color-coded charts let you pinch-to-zoom into detailed heart rate data, step counts, time-stamped symptoms, medications, and logged blood pressure measurements. Cardiogram allows you to see the connection between your symptoms, how you’re feeling and heart rate information you can share with your doctor. You can also set heart rate alerts for high and low readings and connect a family member so they can see your data.

Cardiogram: Migraine IQ helps you understand what’s going on in your body when you have migraines. If you complete your daily log, we will use your individual data to tell you how likely you are to have a migraine in the next 48 hours. This allows you to take steps to end your migraine before it begins!

Compatible smartwatches include: wear OS, Samsung Galaxy, Fitbit, and Garmin.

We take your privacy seriously. We use healthcare-grade encryption and we never sell your data.

The design and features of the app are well curated, definitely above the average when it comes to other heart measurement apps around. However I can't seem to find a way to sync my measurements to Google Fit. New measurements don't appear on my Google Fit account, and I can't seem to find a way to perform automatic measurements each n minutes or sync the data to Google Fit each m minutes, like other apps do.

Hi Fabio, Thanks for the feedback! We get writing to Google Fit as a feature request a lot, and will hopefully be working on it soon!

Hi Mel, this isn't the experience we want for any user. Can you verify you sent us an email to [email protected]? The support team is amazing at responding to all emails within 24 hours. I couldn't seem to locate a user profile or an email using your name here. Hope to hear from you soon.

Sorry but my rating dropped again. Cardiogram is just average now with nothing that stands out from most other cardio apps, including the stock app that comes with my watch(s). The developers are EXTREMELY slow to respond to and resolve problems and customer service is only responsive when you reach out to or demand a refund from Google. What once was the best cardio app is now just average and certainly not worth the premium subscription
