Grid Ref UK and Ireland – Your Grid Reference App!
App will operate internationally, but the “Grid Reference” information is intended for use in the British Isles (UK and Republic of Ireland). App includes a graphical guide to the GB and Irish National Grids.
Ideally suited for use by walkers, hikers and outdoor sports enthusiasts. It is recommended that you should always carry a map and physical compass when on outdoor pursuits.
For best results, use in a flat position, not an upright position. Much like a traditional compass. Use in an open space, where possible, away from trees, buildings and sources of interference.
The screen can, optionally, be set to stay on, for continued on-screen display of Grid Reference information.
Compatible with handsets that feature GPS hardware. You may have to grant the app permission to use this information.
Users can opt to Get 10 Figure Grid References and Remove All Ads from the App, via an In-App Purchase.”
5. GridPoint GB
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.

Thanks to Google Maps you can find your location using your coordinates.
Be aware that the best localization you can get being outside during sunny weather.
It is extremely important because trying to get coordinates at home might be difficult.
Latitude and longitude are displayed in both decimal format and one of following:
– DMS degrees, minutes and seconds sexgesimal
– DDM degrees and decimal minutes
– DD decimal degrees
– UTM Universal Transverse Mercator
Internet data connection not needed.
– Take a photo from your current geographical position and share it with friends and family
– Save photos in history.
– Adjust photo overlay settings to your need such as text color, font size and text position
– Copy data to clipboard
– Share current location with your friends
– Export or import your data from other device, even from other system

7. OS Locate
“Make the most of your adventures in the great outdoors with OS Locate. Used alongside your Ordnance Survey map, OS Locate is a fast and highly accurate means of pinpointing your exact location on the map, anywhere in Great Britain. If you have lost your bearings or simply would like a little reassurance, OS Locate is the ideal companion for all enthusiasts of the great outdoors.
The app converts GPS location readings from your mobile phone to Ordnance Survey National Grid references, enabling you to determine precisely where you are on an Ordnance Survey map. No mobile signal? No problem; OS Locate does not require a mobile signal to function – the inbuilt GPS system can be relied upon, even in the most remote areas.
Simply download the app and switch on your device’s location services (Settings – Privacy – Location services).
OS Locate is packed with additional features. The ‘Share’ button allows you to connect with friends and family via messaging and social media – let them know where you are, how your adventure is progressing and what time you will be home. Use the handy digital compass to take your bearings – always ensuring you are on the right track. For those who are keen to learn more about maps and navigation, the ‘About’ button hosts a wealth of information including hints and tips and a guide to map reading. In addition, you will find simple yet comprehensive guides on how to use eastings and northings.
OS Locate – know where you are.
OS Locate is a complementary tool for Ordnance Survey paper maps. You should always have an Ordnance Survey paper map and baseplate compass when exploring the great outdoors.
Continued use of GPS running in the background can dramatically decrease battery life.
Please ensure your Location Services are turned on.
OS Locate has been updated to provide even greater peace of mind by providing accurate altitude information. As this is taken from the GPS signal, it will always be available.
Also new for version 1.1, OS Locate will automatically detect whether you are outside Great Britain, and convert Ordnance Survey’s Northing and Easting location information into internationally recognised Latitude and Longitude readings, which can be used anywhere in the world.
Finally, Ordnance Survey has partnered with Silva Compasses to update the virtual compass feature to use Silva’s trademarked design for greater usability.”
