Fall Detection is one of the best safety features on your Apple Watch. As you can probably guess by its name, this feature lets your Apple Watch “know” whenever you fall.
When it detects a hard fall, your Apple Watch will ask you if you’re okay; if you don’t answer within a few seconds, it’ll notify your emergency contacts and call 911.
Granted, this feature isn’t 100% accurate. Sometimes, you might get a notification if you punch something too hard or if you move in a certain way. Still, it’s a great feature to have enabled in case something happens — and it’s saved more than a few lives.
