Detect Your Falls
Your Apple Watch comes with a feature you hopefully won’t ever have to use. It’s called Fall Detection, and as you can guess by its name, your Apple Watch can know whenever you fall down and ask you if you’re okay.
Fall Detection works really well most of the time, but if you have an older model or if you do a lot of extreme sports, you might trigger it by mistake.
Once your Apple Watch detects that you fell, you’ll get a notification asking you if you actually fell down and if you need to call for help. If you don’t respond to this notification, your Apple Watch will assume you’re unconscious and automatically make a call to emergency services and notify your emergency contacts that you’re in trouble.
