Apple Watch Series 4 New more information

Update: If you live in the US, you can now use the Apple Watch Series 4's ECG feature. It has yet to launch in any other countries.

There's a new Series 4 watch 4 -exclusive infographic Watch face, Which lets you have as many as eight complications apart from showing the time and a calendar entry. Each of the four corners of the display allows for one Complication, and there are four more within the dial. This allows people to customize the watch face to suit their needs and get all the information they need and get all the information they need at a glance.

As nice as it is to have all these options on the Infographics why you can't instead show information from certain apps. Apple's own apps such as Messages and Phone can't be added as Complications on this watch face, which is baffling. We'd have expected that all of Apple's apps would be well-integrated with watch faces, clearly, that is not the case here. However, a new report suggests that this could be coming soon

Third-party developers still can't crater watch faces for people to download, but we can keep hoping that that's in the works for next year's release. 

With the series 4, Apple has reduced the bezels considerably on the display, rather considerably on display, rather cleverly it must be said. Most of the UI (user interface) in the Series 4 is black which fits in seamlessly with the display making it look quite bezle-free. What it has also dined is rounded the corners which pushes the screen quite close to the edge. Apple added a new electrical heart sensor to the Apple Watch Series4. The new sensor, along with an accompanying app, will be capable of recording in an electrocardiogram, or ECG. Apple says that feature is coming later this year. There's also a set of heart rate notifications, including one that's looking out for atrial fibrillation (AF), meaning you'll get a pop-up if there's anything that looks sketchy with your heart with regards to this condition, which could lead to life-threatening complications.

Watch 4 also comes with an alert system if your heart rate goes too low or high: should your heart spike or fall hard for no reason for a long enough period (around 10 minutes ) you'll get an alert telling you all is not well, and maybe you should see a physician.

Wave a rather low heart rate from regular running training, and the update did ping in from time to time to refer to us that the heart rate testing was working.

The other key upgrade beyond the design, which we'll get onto in a minute, is more hidden in the heart of the Apple Watch4 -there are sweet touches like a (virtually) clicking Digital Crown that feels like it's clocking through lists on the wrist. It even makes a slight noise, and the whole system is incredibly pleasing 

There are several Watch faces that show the display in its full glory. For instance, the Liquid metal face, one can see the role the curves and edges play in the display of Series 4.

The Watch Faces are more 'complicated' and remarkably pack too much information in this display. You can see the weather, heart rate, UV index, too many other things on the Series4.
