Apple Watch Series 4 launched with ECG support: Price, specifications and features

Its future was uncertain, to say the least, and the uses for one were limited.

But here's the thing: as cool as it may be, the Apple Watch Series 4 is also pricey.

How the Series 4 (right) stacks up to the Series 3 (left) The Series 4 feels larger, but it's also slimmer than the Series 3, which feels bulbous by comparison. Is it worth upgrading to the latest Apple Watch if you have an older model? Let us dive into the matter. Now it comes with three new heart features.

The screen size, for instance, has been increased and stretched out to all four corners of the display. The peak brightness level of 1000 nits is also being retained.

Apple Watch Series 4 sports a new design, thanks to an edge-to-edge display and a new Digital Crown with haptics. The Series 3 will still come in a 38mm variation, though you won't get the incredible display or heart health features.

Are you willing to get the Apple Watch Series 4?

The data coming from the Apple Watch Series 4's on-demand ECG measurements are stored in the iOS Health app, and can be exported as PDFs to be shared with a doctor.

The speaker has been made 50 percent louder, and the microphone has been moved to the other side to reduce echo and improve call quality. Apple also claims that it's two times faster than the previous generation.

The update for watchOS is huge, and it's shipping to all Watch devices (series 1, 2, 3) next week.

Williams also said the watch's battery life would be the same as the previous edition of the Apple Watch, at 18 hours. A Series 4 with Global Positioning System only starts at $399.

The new smartwatch is touted to be swimproof, has Bluetooth v5.0, and has an optical heart sensor. These not only track your activity more precisely.

Speaking about its ECG support feature, Apple said Series 4 Watch will send notifications when the heart rate is way too low. The new Apple Watch also allows users to take an electrocardiogram, or ECG. The feature has been approved by FDA, and will be available to users in the United States later this year. For countries listed in the first release phase, pre-orders will open this Friday, 14 September 2018, and availability begins a week later, on 22 September 2018. One of the major addition is that all band colors and band styles fit any Apple Watch.
