#Apple Watch

Apple introduced the Apple Watch Series 12 and Apple Watch Ultra 4 at its September 9 event. Both are built around a new S11 chip, which Ubergizmo says handles on-device machine learning more efficiently.

On health, the watches get an updated sensor system that improves heart-rate accuracy and adds hypertension notifications. A new Functional Strength Training mode covers resistance workouts. Existing features such as sleep apnea detection and stress and cycle tracking remain.

Software additions lean on Apple's new AI features, including on-wrist translation, summaries of messages and notifications, and voice requests that can work without a paired iPhone.

Apple unveiled the Apple Watch in September 2014 and began selling it on April 24, 2015. The first model leaned on a paired iPhone and pitched itself as a communication, fitness and fashion device. Apple even sold a gold Edition model.

The second generation, in 2016, added built-in GPS and water resistance for swimming. Series 3, in 2017, offered optional cellular connectivity, which allowed calls and data without an iPhone nearby.

Series 4 in 2018 enlarged the display and introduced the electrocardiogram app, a milestone that turned the watch into a health-screening device in supported countries. Fall detection arrived at the same time. Series 5 in 2019 added an always-on display. Series 6 in 2020 added a blood oxygen sensor.
