ECG capabilities, available with the Apple Watch Series 4 and later, allow users to quickly take an ECG by simply placing their finger on the Digital Crown and staying still for 30 seconds. Before the feature launches in countries, Apple must retain regulatory approval from the country's respective and appropriate authorities. The feature first launched in the U.S. in 2018 with the Apple Watch Series 4, following FDA approval.

watchOS 8.3 and iOS 15.2 are currently available to developers and public beta testers and can be expected to be launched publicly in the near future. iOS 15.2 includes several new features, including a redesigned Notification Summary, the Apple Music Voice Plan, Legacy Contacts, and more.

One guess is it might be a medical device requirement.
To have it approved per-region, yes, but to do so in a software update? Why not have a server somewhere that answers "I'm in region x requests" with "OK, you're in"?

Strange that they're hardcoding these regions into the OS, rather than having a separate mechanism to decide who gets to use the feature. I guess it's not a huge deal, but rolling out an entire OS upgrade just to add

public bool IsEcgAvailable
{
switch (user.Region)
{
case China: // new in 8.3
return true;
default:
return false;
}
}


seems a bit much.

Only took three years ? Also annoyingly foreigners are still unable to use eSIMs so my cellular S5 is still just an expensive red ring.
The cellular watches work in many different countries. Or am I missing something?
