Apple  If the watch detects movement after a fall, it waits for you to respond and does not automatically call for emergency services. If the device detects no movement after a minute after your fall, it will automatically call an ambulance. The watch calls your local ambulance service and plays an audio message with information about the fall and shares your latitude and longitude location.
After a call ends, the watch can then send a message to your predefined emergency contacts with your medical ID, complete with location information to notify friends or family of the fall and the request for help. For countries and regions with multiple emergency numbers, Apple Watch calls the ambulance number.
Because this feature is especially useful for seniors and vulnerable elderly people who may be alone for a longer period of time, anyone who is 65 or older must use the Apple Health app, the fall detection feature is automatically enabled. Those under 65 will have to turn it on manually, and it can be a good idea for both children and adults of all ages. You can switch the function on or off as you like. Here's how to use it.
Turning on fall detection
- Open the Apple Watch app on the iPhone and tap the My Watch tab.
- Tap Emergency SOS .  Scroll down and turn the switch for Fall detection on or off.

- Open the Health app on the iPhone, tap Summary at the bottom of the window and find Set medical ID .
- Tap Get started.
- Enter your date of birth and other health information.
- Scroll down to find the Add Emergency Contact button and tap.
- That tap takes you to your contacts, where you can just tap the contact that you want to register and designate their relationship with you. Tap the minus sign next to the contact to change your contact or to unsubscribe from the one you have set. Apple Watch deduces your emergency contact from your medical ID.
- If you want to make your medical ID available via the lock screen, enable Show when locked at the top of the window. In an emergency, this gives your information to first aid providers, so that they know basic issues about any existing medical conditions that you have.
