The Apple Watch is a timekeeping device with many additional features, including the ability to run miniaturized apps. It requires a paired iPhone to work. This may sound like a pain, but it actually enables new capabilities for iPhone owners, such as:
- Capturing more accurate health data for iPhone fitness apps.
- Using Apple Pay on the Apple Watch.
- Having emails, texts, and social media alerts appear on the Apple Watch.
- Automatically logging into your laptop or desktop computer running macOS.
Pairing uses Bluetooth or Wi-Fi. The Apple Watch app on your phone lets you sync data and activate various features and apps for the Apple Watch. As Apple Watch is a separate product that goes beyond the scope of this guide, I recommend you visit apple.com/watch for more details.
