What is Find My Friends?
With the Find My (or Find My Friends) app, you, your family, and friends can share locations and follow each other using your iPhone, iPad, iPod touch, or Mac (with macOS Catalina 10.15). After you and your friends share your locations and accept the follow requests, you can use Find My Friends on iCloud.com to locate your friends on a map.
If you don’t see Find My Friends on iCloud.com, your account just has access to iCloud web-only features. To use Find My Friends and other iCloud features, set up iCloud on your iPhone, iPad, iPod touch, or Mac.
If you’re using another iCloud feature, you can switch to Find My Friends by clicking the feature’s name at the top of the iCloud.com window.
Note: If you joined Family Sharing and your family members are sharing their location with you, your family members are added automatically to Find My Friends and are marked as favorites. See the Apple Support article Share your location with your family.
