GPS2OS - Don’t get lost with your iPhone

I got lost in the Lakes last weekend! Low cloud, difficult terrain. And I'd left my GPS at home to save weight. No worries, I had a map and my iPhone. But the iPhone by default gives lat/long not Ordnance Survey (OS) grid references, so I stayed lost for a little while longer.

There are a myriad of GPS apps for the iPhone. I just wanted one that would give me my current position as an OS grid reference, nothing else. A quick search of the App Store turned up GPS2OS, a very simple app that just gives the current OS grid reference position, and there is also some map functionality if you can get an internet connection. Does what it says, enough said. Give it a go.
