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.

Listener OK ,

Ability to enter a GPS position for conversion.

Great, simply product that does what it says on the tin, thanks for all your hard work...

A really useful feature would be to be able to enter an Irish OS position and for it to be converted to a WGS84 OSGB36 GPS position and vice versa so that on can find it on google or bing maps for pre planning of a route...

Thanks again.

Prefer to message rather than tweet

Update. Can share now by text. Great job.. Not bad app but it would be much more helpful to send my ref. to a contact via text message which needs a minimal phone signal rather than tweet a message which requires at reasonable data connection which will not be available in many remote areas please consider

Developer Response ,

Version 2.2. has just been pushed to the App Store, and should allow you to "share" as you please.

One of the best

This has to be one of the best, most useful navigation apps around, after a sat nav, for confirming your position on an OS map. It very quickly and accurately gives you an os grid reference to check you are where you think you are. Superb, app and can’t recommend it enough.
