How do I get an ECG in Cardiogram?

Cardiogram does not record ECGs directly, but if you have a compatible Apple Watch, you can record an ECG using the Apple Health app, and Cardiogram will import it from there.

✅ What devices support ECG?

To import ECGs into Cardiogram via Apple Health, you’ll need:

An iPhone that supports iOS 17 or later
An Apple Watch Series 5 or newer
The Health app configured and allowed to share ECG data with Cardiogram

⚠️ Cardiogram currently only supports importing ECGs from Apple Health.

ECGs from Fitbit, Samsung, Pixel, or Garmin are not supported at this time.

📲 How to take and import an ECG

Use the ECG app on your Apple Watch to record an ECG
The result will automatically be saved to your Apple Health account
Cardiogram will import the ECG from Health if permissions are granted

To verify your settings:

Open the Health app on your iPhone
Tap Sharing > Apps > Cardiogram
Make sure Electrocardiogram (ECG) is turned on

You can view the imported ECGs in your Timeline in the Cardiogram app, typically shown as a chart entry with ECG details.

❌ Using a different wearable?

Unfortunately, wearables like Fitbit or Galaxy Watch may record ECGs but do not currently allow third-party apps(like Cardiogram) to access that ECG data through their APIs.

We plan to support ECGs from more platforms as soon as manufacturers make that data available.
