Don’t have a heart attack, but the new electrocardiogram feature in Apple Watch Series 4 won’t work when the wearable launches.

Apple isn’t exactly hiding this fact, but it’s certainly keeping it quiet.

Apple Watch Series 4 debuted today in Cupertino with a slew of powerful, new features.

Apple’s fourth-generation smartwatch helps users stay more connected and be more active in significant ways. Featuring a stunning new display, electrocardiogram and fall detection as well as breakthrough communications, Apple Watch Series 4 is a stunner.

Apple’s biggest keynote of the year is just days away and while the iPhone XS will be the main attraction of the event, Apple Watch Series 4 could steal the show with a bevy of new features.

Rumors about the Apple Watch Series 4 have been heating up leading up to next week’s event. Leaked images of the new wearable have already surfaced online, but there’s still a bit of mystery surrounding the new gadget.

Here’s everything we know about Apple Watch Series 4:

The annual Apple event we’ve all been waiting for is right around the corner.

On September 12, the company will host a special keynote from the Steve Jobs Theater in Apple Park, where it will reveal all the hardware it has planned for this fall.

We’re expecting a slew of big announcements, including updates for the iPhone, iPad and Apple Watch. Here’s our roundup of everything Apple is likely to deliver at its “Gather Round” event.

The bigger display on the Apple Watch Series 4 will allow wearers to view more data at a glance and thanks to some new leaks, we now know the exact screen resolution it will come with.

Check out the difference:

Apple debuted a new gay pride watch face for Apple Watch this year at WWDC, but developers have recently discovered that it’s literally impossible to install it if you live in the homophobic land of Mother Russia.

You can now sign into your Microsoft account using your Apple Watch.

Microsoft’s free Authenticator app, which brought password-free logins to iOS last year, has made the leap to watchOS. It’s in beta testing for now, but it’s easy to sign up for early access.

There’s bad news for anyone who’s still a fan of Back to My Mac: Apple is killing off this suite of remote-access applications.

The good news is that Apple’s doing so because all the functionality has been supplanted by newer options. 

It’s highly likely that we’ll see new Apple Watch Series 4 devices at next month’s Apple media event, and a new series of filings suggest that this is even more probable.

Filed with the Eurasian Economic Commission are six new model numbers for next-gen Apple Watches, all of which will run watchOS 5. While that doesn’t tell us too much about the new devices, it does suggest that they are on the way.

In just a few weeks, Apple looks set to unveil the biggest upgrade yet to its popular wearable.
While the external appearance of Apple Watch has not changed much since its launch, recent leaks suggest we can expect a new form factor with a larger screen when Apple Watch Series 4 lands.

In the Photoshop mockup above, I’ve shown how Apple’s next watch might look if it slimmed down and added a larger screen (as the rumormongers predict). That would be pretty cool, but there are plenty of other potential upgrades I’m excited about.
