About this app

GPS OS provides a fast and accurate way to locate your position on an Ordnance Survey map, both in Great Britain and Ireland. • No phone signal required - works in the most remote locations. • OSTN15 transform data for high conversion accuracy (better than 1m). • 6, 8 and 10 figure grid references. • A large, clear, high contrast display ensures you can easily read your position in any light conditions. • Optimises the frequency of position updates depending on battery charge and speed of travel to make sure you can always make calls at the end of the day. • Create waypoints from a map, your current location or manually enter Ordnance Survey coordinates. • Explore waypoints and get directions in Apple Maps. • Share waypoints with other apps or users. • No adverts.
