However, many users have reported that the ECG app is not working on their Apple Watch. In this blog post, I will explain why Apple Watch ECG is not working. This Apple watch guide also includes troubleshooting this issue in simple steps.
Let us start!
Apple Watch ECG Not Working: Troubleshooting Guide
1. Check your Apple Watch Model
The ECG app is only available on Apple Watch Series 4 or later models. With that said, the Apple Watch S.E. also does not have ECG features.
See the complete list of Apple Watches with ECG below.
- Apple Watch Ultra
- Apple Watch Series 8
- Apple Watch Series 7
- Apple Watch Series 6
- Apple Watch Series 5
- Apple Watch Series 4
So, if you own any Apple watch other than that listed above, unfortunately, your watch doesn’t have ECG capabilities.
NB: You must have iPhone 8 or later to use the ECG feature on Apple Watch.
2. Check ECG Available in your Country
Even if you own an Apple watch with ECG, the App may not be available in your country. If you live in a country where the App is unavailable, you won’t be able to use this life-saving feature. Since ECG is a medical app, it is subject to regulations in each country.
For example, in the USA, the Apple Watch ECG is approved as a Grade 2 medical device by the FDA. But in many other countries, it is not yet approved. You can check the complete list of Apple watch ECG App-supported countries on the Apple website. The good news is that Apple is working on expanding ECG availability to more countries, and I hope it will soon be available in your country too.
If you live in a region where the App is not yet approved, then wait for it to get approved in your country. You can check the list of countries where the ECG app is available on Apple’s website, which I already mentioned above.
If you have an Apple watch with an ECG model and live in a country where the App is available but still can’t use it, follow the below troubleshooting tips.
3. Restart the Apple Watch and iPhone
I always recommend that my readers restart their electronic gadgets first if they face any problems. Because simply restarting your Apple Watch and iPhone can fix most of the issues.
Here is how to restart your Apple Watch.
- Press the side button until you see the power-off slider.
- Drag the slider right to turn your Watch off.
- After your Watch turns off, press and hold the side button until you see the Apple logo.
- Done.
Once you have restarted your Apple watch and iPhone, check if the ECG app is working or not. If it still does not work, then follow the next troubleshooting step.
4. Update to the latest O.S.
To use ECG, your iPhone and Apple watch must have the latest iOS and watchOS, respectively.
To check for the latest iOS:
- On your iPhone, open the Settings App.

5. Check if your Apple Watch is in Standalone mode via Family Setup.
Apple Watch ECG requires an iPhone 8 or later varients to work. If you are using your Apple Watch in standalone mode via Family Setup, it does not work. See the list of some features that do not work in standalone mode.

7. Clean the Digital Crown

To clean the digital crown, follow these steps:
- Turn off your Apple Watch.
- Remove the watch band.
- Use a soft, dry, lint-free cloth to wipe the digital crown and the surrounding area.
