Install and set up the ECG app

The ECG app is installed during the ECG app setup in the Health app.

If you deleted the ECG app, you can install it again from the App Store on your Apple Watch if you've completed the ECG app setup.

Follow these steps to set up the ECG app:

Open the Health app on your iPhone.

Follow the onscreen steps. If you don't see a prompt to set up, tap the Browse tab, then tap Heart > Electrocardiograms (ECG) > Set Up ECG App.

After you complete set up, open the ECG app to take an ECG.

If you still don’t see the app on your Apple Watch, you can search the App Store on your Apple Watch for ECG and download it.
