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. -- Ad Supported. Users can opt to Get 10 Figure Grid References and Remove All Ads from the App, via an In-App Purchase.
