‘Postcodes have always been useless for us. If you’re in the middle of a field, it’s no use if the postcode takes you to the nearest house. That’s why we use what3words.’

‘I’m enjoying using what3words to save the amazing places I find, and to share precise starting points for trails with friends. Every runner should have it’

Google Maps is a tool for navigation, public transport and for looking up POIs. what3words has a very different function – it’s an easy way to communicate exact locations, whether that’s spoken over the phone or into a car voice navigation system, or typed into a taxi app or a website checkout page.
If you’re given a what3words location, you can open it in the what3words app, then tap ‘Navigate’ and select ‘Google Maps’ to open the exact location in Google Maps and get directions.
Without phone signal, the app functions the same as when you have no data connection: you can view the location of any what3words address you enter. You can also navigate to it using compass mode.
To share a what3words address over the phone or in a text message you need phone signal. To load maps, or share in other apps or social media, you need a data connection.

The minimum platform versions we support for new app versions are Android Marshmallow (6.0) and iOS 11.
If your device is incompatible with the versions above, you won’t be able to use the app, but you can still access what3words via what3words.com on your web browser.
