Grid Reference Free is a free Android application developed by Torvus Consultants that displays the UK Ordnance Survey (OS) grid reference for your current location. This app is a handy tool for those who use OS maps in Great Britain and want to know their current location within the grid reference system. With the app, you can see the grid reference for your current location with up to 10 figures accuracy.

In addition to the grid reference, the app also displays your WGS84 Latitude and Longitude values, making it easier to locate your position on other map systems. The app also checks whether your current position is within the correct range for UK grid references, ensuring that you get accurate grid references every time.
