OS Locate is a free Android app developed by Ordnance Survey Ltd, designed to complement Ordnance Survey paper maps. This app is an ideal companion for all outdoor enthusiasts who want to determine their exact location on an Ordnance Survey map, anywhere in Great Britain. The app converts GPS location readings from your mobile phone to Ordnance Survey National Grid references, allowing you to pinpoint your location precisely. The app does not require a mobile signal to function, making it reliable even in remote areas.

The app is packed with additional features such as a digital compass, Share button to connect with friends and family, and comprehensive guides on how to use eastings and northings. The app relies on your device's internal compass, and accuracy generally increases the longer you have the app open. Please note that continued use of GPS running in the background can dramatically decrease battery life. Ensure your Location Services are turned on and always have an Ordnance Survey paper map and baseplate compass when exploring the great outdoors.
