The what3words app helps you find, share and navigate to any precise location.

We’ve given every 3m x 3m in the world a unique 3 word address. This simple and accurate way to talk about location makes it easier to meet up with friends, discover and tell others about amazing places, and explore the world without getting lost.

You’ll see 3 word addresses displayed by hotels, restaurants, travel guides and websites. They can be used in 20+ languages and are much simpler to remember, use and communicate than regular addresses. They’re also far more accurate and reliable.

Use the app to:
- Find your way to anywhere in the world, even where street addresses don’t exist
- Tell your friends precisely where your picnic is
- Always find your tent at festivals
- Tell your taxi exactly where you want to go
- Plan and share your off-roading or hiking waypoints

Wow!! Mind blowing app and concept.


What an amazing concept.
Apparently now being installed in Mercedes cars.
Watch this space!

The positive applications for military, police and even delivery companies are brilliant.
The ability to pinpoint a 3m square and convey that information using 3 words instead something like a 10 digit grid reference is incredible.
Our brains struggle with memorising long numbers quickly, but with 3 words a mental picture can be produced, or they can be easily remembered and passed on to other people trying to find the location.

I am currently spreading the word about it to my friends, family and colleagues. I can't believe I've only just discovered it!

Blown my mind with the simple brilliance.
Well done developers

Incredible idea and concept


Used this app for the first time in the summer to find my friends tents at a festival - so useful! Been using it for addresses with my friends in everyday life ever since. Absolutely brilliant idea that’s going to change the world

Mind blowing app!


I simply LOVE this App. The stuff of spy stories but also a Really useful and user friendly tool. Lets hope this gets adopted widely - could be a real game changer.
