Hello. I was wondering if there was a app that allowed you to create a treasure hunt based on GPS. Basically, I would want to be able to set clues, and the clues lead you to a location. Once you get to that location it give the next clue and so on until you Finnish. If such a app does not exists how hard would it be to create? I know some C and java script. I think I posted this in the right place, if not, sorry, Im new!

Thanks,
Jack
