A new potentially life-saving app can tell emergency services the precise location they need to go to when someone needs assistance and Thames Valley Police is encouraging everybody to install it on their smartphones.

What3words divides the entire globe into 57 trillion 3m x 3m squares – if someone needs assistance it will then provide a specific three-word code for where they are, making it a lot easier for the emergency services to find someone in a rural area or unfamiliar location. 

The app, which is used by emergency services across the country, is free and doesn’t require an internet connection to use – for more information please see the what3words website
