NOTE: iOS13 brought significant changes to the Find my Friends app, read about how to use Find My with Siri.
Find my Friends is a useful app for finding family and friends who have consented to share their location with you.
It can be used on the iPhone, iPad, or iPod touch (iOS 8 or later) and the Apple Watch (watchOS 3 or later).
It’s great for locating friends or family in a crowded place, checking of guests are close to arriving to a party, and for parents who would like to keep tracks of where their young kids are.
As always, Siri can be activated by pressing the home button (or side button on the iPhone X) or saying ‘Hey Siri’.
As long as a contact has shared their location with you, it’s easy to find out where they are:
Hey Siri, where is Jane?
If you’ve assigned relationships to contacts, you can use informal language too:
Hey Siri, where is my son?
This finds your sons location (as long as he is with his device) and displays it on a map, including his current distance away from you.
Other examples of ways you can ask for friends locations are:
Is my wife at work?
Who is here?
Where are all of my friends?
Of course, the usefulness of this depends very much on how happy people are with other people knowing where they are.
