Apple Watch Series 4's most anticipated new feature, an electrocardiogram (ECG) app, is expected to start in the USA before it officially rolls out elsewhere. It appears that a simple software change can make the feature available, no matter where you are, according to 9to5Mac.
Like iTunes and Apple Pay before that, the ability to use the ECG feature is expected to be based on the software area selected on Apple Watch and iPhone. In other words, if you change these settings on your devices to the U.S. region, the ECG function should work.
The Apple Watch ECG restriction is software-based, is already a good sign, since software constraints are inherently easier to bypass when compared to hardware. By being based on the region, users will be able to access the feature by changing the region on their iPhone and Apple Watch so that other features like Apple News can be enabled on unsupported countries.
Apple Watch Series 4 includes electrodes embedded in the digital crown that work with the backbone of the device to generate an ECG waveform. This information can help determine if the user shows signs of atrial fibrillation. To make this requirement, Apple needs approval from national health agencies wherever it sells the portable device, such as the US Food and Drug Administration (FDA). This process can take a long time, especially in places like Canada and the EU.
9to5Mac Notes Apple may make changes to how it determines placement settings for the ECG app before it is released to the public. Therefore, there is no guarantee that the software solution will actually work when the feature is launched. Time will tell.
Looking forward to using the ECG feature on Apple Watch?
