Book excerpt: Explore everything your Apple Watch can do in watchOS 10! Version 4.2, updated December 13, 2023 Get to know your Apple Watch and customize it to help you focus on what you care about most. Tech expert Jeff Carlson helps you understand the watch mindset, pick the watch model that’s right for you, set up and share its faces and their complications, get the notifications you want, take advantage of the health and fitness features, handle communications, and learn how the controls and core apps work.n The Apple Watch has become the world's best-selling watch, as well as the most popular wearable digital device. Since the device's introduction in 2015, Apple has developed numerous new watch product lines, vastly expanded the device's capabilities, and enabled developers to create entirely new apps and tools. The Apple Watch hides an enormous amount of technical complexity behind that unassuming touch screen, and with help from author Jeff Carlson, you'll unlock every last bit of its power. With watchOS 10, Apple dramatically changed some of the core watch interactions, which Jeff covers here. Take Control of Apple Watch covers all Apple Watch models through Series 9 and Apple Watch Ultra 2, as well as all the new features introduced in watchOS 10. Jeff walks you through getting to know the Apple Watch (including how to pick one out if you haven’t already), along with topics that teach you how to navigate among the watch’s screens with the physical controls, taps on the screen, and Siri. You’ll also find advice on customizing watch faces and sharing them with others; taking advantage of the electrocardiogram (ECG) capability and blood oxygen sensor, plus the temperature sensors introduced in the Series 8 and Ultra; getting the notifications you want; handling text and voice communications; using Apple’s core apps; and monitoring your heart rate, hearing, and monthly cycle to improve your overall health. A final chapter discusses taking care of your Apple Watch, including recharging, restarting, resetting, and restoring.
