Find Devices (Even Offline Ones)
Apple has combined Find My iPhone and Find My Friends into a single Find My app in iOS 13. But it’s not just a cosmetic change. The new Find My app has some clever capabilities that weren’t available before.
The most notable is the ability to locate devices even if they’re not connected to the internet. Apple does this by bouncing Bluetooth signals off of other Apple devices in the area. And don’t work, it does this while protecting your privacy and security too.
