Description
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.

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.

Ratings and Reviews
An absolute lifesaver!
I really enjoy the whole map reading navigation thing, I’m quite an obsessive map reader, but there can be occasions when even with the best will in the world, the situation can become confusing. I live on the edge of Dartmoor and there’s been times when the thick mist has come down in areas that I’m really very familiar with but even still, and thanks to my GridPoint, I realise that I’ve drifted hopelessly off course, but thanks to GridPoint I can now reset my compass bearing. Also the really good thing to be aware of is that GridPoint doesn’t need a phone signal to operate as it only relies on the GPS signals which always seem to be available. For me it’s always been 100% reliable, it’s never ever yet failed and I get out into the wilds quite a lot and in some pretty remote parts of the UK, Scotland too. IT’S JUST BRILLIANT! Whenever I bump into other walkers I’m very often extolling the virtues of GridPoint, I think it’s a real must have item for walkers and ramblers, and it’s so clear and straightforward to use.
Many thanks George MacKerron!

Excellent with a paper map
I am a Viewranger user as well as having a high end Garmin GPS. However I always carry a paper map and this app is really good for relating its gps position to your position on a paper map. This is down to the clever and unique (as far as I know) graphic representation of the relevant grid. OK, you could argue that it would be better with an OS map layer under the graphic but that would mean buying or subscribing to digital OS maps. The thing for me is that it encourages me to use the paper map and helps me read grid references more easily.
Another great feature is that you can see the difference between grid, true and magnetic north. It would be good perhaps if you could also see grid magnetic angle without having to work it out but maybe in a future update?
All in all a clever and effective app for anyone from a casual user to a professional.

A must have app for walkers, and climbers alike.
Download this app, ensure that’s it’s on your phone before you go out into the wilds, and hope that it remains an unused, waste of space on your phone.
The app does exactly what it says on the tin. It gives you your location, in a number of formats. From grid reference, to Lat & Lan and more besides. And it does not require a mobile signal to work. Just GPS.
When you need it, it could be a life saver.
