How to enable ECG on Apple Watch in unsupported countries

One of the best features of the Apple Watch is the ability to take an electrocardiogram reading right from your wrist. If you bought your Apple Watch in a country where ECG is not officially available yet, here is how you can enable ECG on Apple Watch using a simple jailbreak tweak.

Enable ECG on Apple Watch in all countries

Before you being, take note of the following:

  • Your iPhone must be on jailbroken iOS 13.5. You can use unc0ver 5.0.0 or checkra1n to jailbreak iOS 13.5.
  • Your Apple Watch (series 4 or series 5 only) must be on watchOS 6.2.5. This guide will work on older watchOS versions too but you would have to re-pair your watch without restoring from a backup.

If you are on older operating system versions, your iPhone or Apple Watch must have been purchased from a country where ECG is officially enabled on these devices.

Now for the actual steps to follow to enable ECG on Apple Watch, regardless of country or region:

  1. Open Cydia and go to BigBoss repo.
  2. Search for ‘ECG Enabler‘ tweak and install it on your iPhone.
  3. Open the Health app on your iPhone, tap on Browse, and search for ECG to enable the feature.
  4. If the feature does not work right away, unpair and re-pair your Apple Watch to your iPhone and restore the backup. If you are not on watchOS 6.2.5, you will have to re-pair your Watch without restoring the backup, for this tweak to work.
  5. Once ECG works on your Apple Watch, you can remove ECG Enabler, and even un-jailbreak your iPhone, but the tweak will continue working. However, if you reset your iPhone or format all content/settings, you might lose this tweak, so keep that in mind.


Once you enable ECG on your watch, you can take readings by opening the ECG app on your Apple Watch and pressing and holding your finger on the Digital Crown for 30 seconds. The reading will be automatically saved in the Health app on your iPhone and can also be exported as a PDF to be shared with your doctor. Read more on Apple’s support website here.
