Not actually available

Recently my Apple Watch series 6 removed the ECG (EKG) and Blood oxygen apps from the watch. They are searchable, but not downloadable. They are there, but cannot be used. Absolutely useless tech. Apple is having issues and they need to get on it. The EKG and blood oxygen were one of the huge selling points and without them, not really needing to upgrade past a series 3.

Great

Works as expected

ECG issues

First off it says it’s available for my watch series and then other places it says it’s not absolve for my watch series and won’t let me download and if it only is on one type of Apple Watch it should be available on all of them for people like me who have health issues

???

when i try to download it on my applewatch, it says it requires an iphone. but when i try to download it from my iphone, it says it can only be downloaded on an applewatch. if anyone knows how to solve this please let me know!! super frustrating.

It would be nice a virtual “print out” of your ECG that even though it can’t tell you about your underlying rhythm your Doc can at least look at it when you have symptoms

FAQ

What is ECG and what does it do?

The ECG app on Apple Watch Series 4 or later can take an ECG similar to a single-lead electrocardiogram. It records your heartbeat and rhythm to check for signs of atrial fibrillation (AFib) or sinus rhythm.

When should I use the ECG app?

You can take an ECG at any time, especially when you're feeling symptoms like a rapid or skipped heartbeat, or if you receive an irregular rhythm notification from your Apple Watch.

Can the ECG app diagnose AFib?

The ECG app can indicate whether your heart rhythm shows signs of atrial fibrillation or sinus rhythm. It is not a substitute for a medical diagnosis and results should be shared with your doctor.

How can I share my ECG results?

The app saves your ECG waveform, classification, and any noted symptoms as a PDF in the Health app on your iPhone. You can then easily share this PDF with your doctor.

What Apple Watch models support the ECG app?

The ECG app is available on Apple Watch Series 4 or later. It is not supported by Apple Watch SE and may not be available in all regions.

Is the ECG app free to use?

Yes, the ECG app is free to download and use. It does not have any in-app purchases or advertisements.

How often is the ECG app updated?

The latest version of the ECG app is 1.4, and it was last updated on December 12, 2025. Updates typically include performance improvements and bug fixes.

What is the age rating for the ECG app?

The ECG app has an age rating of 17+. This is likely due to the sensitive nature of health data and the potential for misinterpretation of results without professional medical guidance.
