Locate a device in Find My on iPhone - Apple Support

The use of Find My, with suitable aforeknowledge & preparation of the device;

could be most useful in itself to find someones whereabouts if or when lost.

"When you share locations with your family, they can see your location in Find My.

You can also get notified when family members change their locations—for example,

if a child leaves school during school hours."

Get directions to a device

You can get turn-by-turn directions to your device if you see its location on the map.

The locations indicators & other details might not be adequate for this.

Maybe some other discussions readers may have some ideas in this?

.And have never lost anyone or needed to find another person with iPhone.
