The Apple Watch is more than a timepiece and a fashion accessory. The watch is designed to be a very personal assistant, from paying for groceries or a coffee to keeping a detailed record of your daily physical activity. Author Scott McNulty has organized the book around events and activities, showing how to use the watch in various settings. The book starts off with an essential “Apple Watch 101” section that gets you up and running quickly. You learn the watch’s gestures and presses, how to use the digital crown, and how to change the band, for example.
