If you’re at a house or business, it’s easy enough to communicate where you are: just give an address or a google-able name. But if you’re trying to meet someone at their blanket on the beach, or telling a friend where in the woods you’re lost, that’s a harder problem.
Latitude and longitude are made for this, but here’s a much more user-friendly method: what3words. Every 3-meter-by-3-meter square of earth has three words associated with it. What3words’s global headquarters is in London at a spot called ///filled.count.soap. Looking around my own neighborhood, I can tell you the spot where birdwatchers congregated this spring to gawk at a bald eagle nest is ///threading.thrusters.rulers.
Emergency services use this app in the UK: if you’re in an accident but aren’t sure how to describe where along the road you are, they’ll have you download the app and give them your three-word code. Even though that’s not routine here, the codes are still a handy way to remember and communicate specific areas regardless of whether they have a formal name or address.
The app lets you enter a code and find directions to it, so you could use what3words to find your car in an airport parking lot, or meet a friend at a specific trailhead to go hiking. You can also make lists of locations in the app, for example your favorite fishing spots. Best of all, it doesn’t require a data connection to work—just your phone’s GPS.
