Ignoring the Safety Features
Arguably the most important features of the Apple Watch relate to safety. While it can keep you connected and healthy over the long-term, an Apple Watch can also help save your life in a pinch — if you actually set up and use the provided features.
For one, add important health information and emergency contacts to your Medical ID. Familiarize yourself with Emergency SOS, which can let you contact first responders. (If you have a Cellular Apple Watch, Emergency SOS will work even without a cellular plan.) Make sure to enable irregular heart rate notifications and fall detection.
