  16. Have you tried out our latest iOS app, OS Locate? It’s perfect for pinpointing your exact location when you’re exploring Great Britain. It’s designed to be used alongside an Ordnance Survey map, and the app converts GPS location readings from a mobile phone to Ordnance Survey National Grid references, helping you determine precisely where you are on one of our maps. OS Locate is free to download and, importantly, it doesn’t need a mobile signal to function, so the inbuilt GPS system can be relied upon, even in the most remote areas. It can be used as a useful tool for walkers, cyclists, runner, canoeists, horse riders and many more people. • Our developer team will be working on an Android version of OS Locate in 2014 as well as looking at other options, such as Windows 8.
