Awful. Been playing with this for a couple of hours. Honestly, I'd go back to paper maps rather than trust using this. The ratings speak for themselves. Almost no one likes it. I assume the owner of Viewranger wanted out for whatever reason and that's fine. I will be sad to lose my tracks and my OS maps. Nothing lasts forever though...and this app should have been drowned at birth. Can't find anything good to say about it. Sorry. OA's responses on here have been empty drivel.
