It’s an app that maps the world in 3 metre squares each with a 3 word address. It was designed to help finding locations in third world areas without postal systems but is now used by emergency services to locate lost people. Tell the 999 people the three word address displayed on your phone and they can land an Air Ambulance on your head.
