Apple Watch Series 4 with ECG sensor, larger display unveiled

Apple Watch Series 4

The Apple Watch Series 4 has arrived alongside the new iPhone XS, iPhone XS Max, and iPhone XR. The watchOS 5-running wearable retains the same squarish design as its predecessors, but the corners are now curved and the bezels have dramatically been reduced so you get 30% more screen.

Thanks to this change, the Apple Watch Series 4 is available in 40mm and 44mm sizes. All this space allows up to 8 complications to live side-by-side, showing you all sorts of information from the weather to contacts. The panel is also powered by a new LTPO technology for superior power efficiency.

Apple Watch ECG

Perhaps the most groundbreaking change is the introduction of an ECG (electrocardiography) sensor. Apple has placed electrodes on top of the Digital Crown and the back crystal to read your heart signals. You just have to place your finger on the crown for 30 seconds and the smartwatch will generate an ECG waveform which you can send to your doctor.

The Apple Watch has already helped save lives with its heart rate sensor, so this could take things to the next level. The company claims Series 4 of the watch can classify if the heart is beating in a normal pattern or if there are signs of Atrial Fibrillation. The ECG app is coming later this year though, so you’ll have to wait a while to try it out.

Apple has also incorporated an interesting new feature – fall detection. If you’ve taken a hard fall, the wearable will ask if you’re alright and whether it should kickstart Emergency SOS. If you don’t respond in 60 seconds, it’ll automatically start the process.

Apple Watch Series 4 Improvements

The Apple Watch Series 4 has further improved in the cellular department with a 50% louder speaker optimized for calls, Siri, and Walkie-Talkie. The microphone now has a new home in order to reduce echo for better sound quality.

In terms of hardware, Apple’s using a custom 64-bit dual-core S4 chip for 2x faster processing and up to 18 hours of battery life. The Digital Crown looks the same on the outside, but it’s gotten revamped on the inside with haptic feedback so you feel every click.
