GridPoint GB vs Postcodes & Postbox Search

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.

Need a postcode or postbox fast? We’ve got you covered. Making deliveries or driving a cab? Filling out paperwork that needs your full postcode? Or maybe you’re trying to find the nearest postbox or post office? No worries. Just open the app and sort it in seconds. You can also search for a postcode by address or tap anywhere on the map to get the one you need. Save your favourite places too and look them up later when it suits you. Got an Apple Watch? Brilliant. Your current postcode is just a tap away, right on your wrist. Fun fact: Some British Overseas Territories have their own UK postcodes: • TDCU 1ZZ – Saint Helena, Ascension and Tristan da Cunha • BBND 1ZZ – British Indian Ocean Territory • BIQQ 1ZZ – British Antarctic Territory • FIQQ 1ZZ – Falkland Islands • GX11 1AA – Gibraltar • PCRN 1ZZ – Pitcairn Islands • SIQQ 1ZZ – South Georgia and the South Sandwich Islands • TKCA 1ZZ – Turks and Caicos Islands Please be aware that using this app will requite you to use a subscription.
