NO PUN INTENDED, but we’ve lost track of the number of times the Find My app has helped us locate lost items or warned us of items we’ve left behind. From errant AirPods to misplaced iPhones and the odd AirTag–enabled wallet, purse or bag, the Find My apps have saved us a great deal of stress and probably a lot of money too.
Your Apple Watch has three apps that use Apple’s FindFind My network, which is enormously clever; whenever your device or AirTag is within range of an Apple device, it sends an encrypted signal to Apple via the device’s Bluetooth connection. The other device doesn’t see the signal; it just passes it on to Apple — and when you activate the Find My app, the app simply asks Apple “hey, where’s that device?”
