SF Text OS Grid Ref

This app allows you to text your current UK Ordnance Survey Grid Ref. The application uses the GPS of your device to calculate the Ordnance Survey Grid reference. You can send it with predefined text messages or write your own. Once written the grid reference in the text message will continually update.

In the preference section there is the ability to set an emergency phone number. If the predefined emergency message is selected then this will automatically populate the phone number field.

Note: This app should not be used for the primary source of navigation. Take a map and compass and know how to use them!
