what3words is a new universal address system.

w3w is a giant grid of the world made up of 57 trillion squares of 3 metres x 3 metres. Each square has been given a 3 word address comprised of three words from the dictionary. What three words? Carefully chosen ones to help make important locations more memorable. [Go to the settings menu to change the language for the "three words".]

Explore the map, zoom in to see the grid, and tap the wordbar to share a 3 word location with your friends.
You can also use the app to purchase an additional, personalised address for any 3m x 3m square: it's called a OneWord. It always starts with a *, and you can move it to your current location, or any other location whenever you choose.

You can use the w3w app to find, share and get directions to any 3 word location or any OneWord location.

w3w is universal. You can email or SMS a w3w, say it over the phone, write it down or just remember it. It's the easiest form of address communication.

Next time you ask someone where they are, just ask them "What 3 words?"!

We hope you enjoy what3words!

Please note: to function properly, the "what 3 words" app requires an internet connection, either via 3G, 4G or WiFi.

    App won't start without a data connection. Can't even read the FAQ or view tutorial, let alone look up entries. Yet the FAQ says it works offline. Very disappointing. But idea is brilliant. Just the app needs work.
