Hillnav GPS complements the hill walkers map and compass, by pin pointing your exact location when you are not sure.
Hillnav GPS displays your current grid reference and height above sea level in large easy to read letters. It compliments a map and compass, giving the experienced hill walker an accurate location in unknown areas or in poor visibility.
No matter where you are in the UK or Ireland, Hillnav GPS knows where you are. Grid references can be displayed in the UK or Irish ordnance survey format, and switching between them is quick and easy.
When you are off the beaten track, Hillnav GPS keeps on working. It doesn't need a mobile phone signal to operate. It uses the GPS equipment already inside your iPhone, so you can explore anywhere you like.
