Off-Grid GPS is a navigation app designed for situations when you can't rely on mobile data or a mobile signal but you need to know that you're heading in the right direction. Going trekking in the middle of nowhere? Heading out to sea? Driving across Africa? Pick your locations and the app shows you where they are relative to where you are now and how quickly you will get there.
