In the eight years since Apple released the Find My Friends app, location sharing has become a key aspect of many relationships. Some claim they feel safer knowing their close friends, family or significant other have their location in case of an emergency.

Find My Friends recently helped a North Carolina mother find her teenage daughter in a ravine, after a car accident had left her unable to reach her phone. Both the mother and daughter say that the app was lifesaving.
