The Apple Watch Series 4’s ECG feature releases
One of the Apple Watch Series 4’s headline features is the ability to take an electrocardiogram (ECG) measurement of your heart’s electrical pulses to gauge your heart health and give a vague baseline for your overall wellness. It’s been approved by the American Food and Drug Administration, but it wasn’t quite ready for release. But it is now, and Apple Watch Series 4 owners can update their phones and give the feature a whirl. It’s easy to use; simply open the app on your Apple Watch Series 4, then hold your finger on the Digital Crown until the measurement is complete.
Design and display
The Apple Watch Series 4 comes in two sizes — 40mm and 44mm – and also brings along a 30 percent larger display. There’s also a redesigned modular watch face with more detailed and graphic information. Users can see stocks and heart rate, track scores from sports teams, view boarding information, and more. In terms of colors, the Series 4 comes in three aluminum finishes — silver, gold, and space gray. The Series 4 also comes in gold stainless steel with a Milanese band, in addition to the silver and space black stainless steel options. The new bands will also work with any of the Apple Watch predecessors.
For the most part, the Series 4 looks similar to its predecessors, although there’s a new digital crown with haptic feedback. This will allow for a more responsive feel when you flip through items on your watch. The speaker has also been completely redesigned, making it 50 percent louder, and the microphone can now be found on the opposite side — far away from the speaker. This will hopefully help to reduce echo and make phone calls much clearer. The back of the Series 4 is made of black ceramic and sapphire crystal, allowing radio waves to pass through the front and back. Apple says this is meant to improve cell reception.
