Apple has released the latest update to the Apple Watch, bringing with it a major bug fix, expanding the availability of the ECG app, and more.

On Monday, Apple officially launched watchOS 5.3 to the public. While the latest update doesn’t add a slew of new features to the mix, it is not without its primary additions. That includes, just to start, broadening the availability of the ECG app to two new regions, and an important bug fix.

First, the update itself. watchOS 5.3 is free to download and install. To get it on your smartwatch, you need to first make sure that it’s connected and within range of your iPhone, that the Apple Watch has at least 50% battery life, and that it’s on its charger. You then need to open the Apple Watch app on the iPhone, select General –> Software Update and following the onscreen instructions.

Apple’s release notes confirms that watchOS 5.3 is bringing the ECG app to both Canada and Singapore. This means folks with the smartwatch, running the latest version, in these areas will get irregular heart rate notifications.

In addition to that, watchOS 5.3 also includes a bug fix to the Walkie-Talkie app on the smartwatch. Apple recently suspended the app due to an eavesdropping vulnerability. But with the latest update, that is patched up and the app is good to go again.

You will also need to install the iOS 12.4 update that was released earlier today as well to get all of the benefits of watchOS 5.3.

Apple’s watchOS 5.3 is available now. If there are any other major new features discovered following the launch, we will update this post accordingly.
