To get help faster in an emergency enter a place name or street address into the search bar at the top of the screen. If it is not where you are navigate to a square on the grid for your current location. Click on that square. 3 words come up at the top of the screen to describe this square which you can give to the call handler. It works offline - ideal for areas with unreliable data connection. The emergency service can then coordinate a response directly to the exact location where help is needed.
