GridPoint GB vs Spine Guide

If you have a paper Ordnance Survey (OS) map, GridPoint GB makes it easy to locate yourself — even when you've got no mobile reception. The app uses your iPhone's GPS and compass to provide your current grid reference and heading, and illustrates how to use this to locate yourself on the map. Coordinate conversions are implemented via OS's OSTN02, accurate to within 1m. The app also: * Includes an Apple Watch app and associated complication * Reports full numerical easting and northing, tetrad, raw latitude/longitude, a nearby postcode, and various heading parameters * Has a sharing facility so you can share, copy or store your location * Calculates next sunset and sunrise times * Can emit a distress signal, just in case All features are free to use — the in-app purchase is simply a tip you can give the developer to show appreciation. For details and instructions, please see http://mackerron.com/gridpointgb/ Please note: this app works ONLY in Britain (i.e. England, Scotland or Wales). It does not operate in other parts of the UK or British Isles and cannot provide coordinates in Northern Ireland or the Republic of Ireland, since a different coordinate system is used.

This feature is used to show you relevant content based on your location. Note that you do not need to be at the locations in Sheffield featured in order to access the app content. The app also optionally uses Location Services to determine your location when the app is running in the background. It will trigger notifications when you are close to a location of interest. However, as with all apps that use location, please note that continued use of GPS running in the background can dramatically decrease battery life. During Open Doors 2026 on 20th October, content in the app is ‘unlocked’ by interacting with NFC tags at physical locations within Sheffield. Each scan will earn the user points. The user can optionally choose to join the event leaderboard, and a chance to win a £100 gift card.
