Duplicating expense

I bought maps in TheMapFinder. Now I have to buy them again? No thanks

Released with fatal bugs

In July of 2016 I used this app for walks in the Yorkshire Dales. I had planned the trip carefully, researching walk routes on the Internet, and downloaded about a dozen offline maps, a key feature of the app, designed so you can view a map in a wilderness area without data connectivity. The maps saved ok, but I discovered when I tried to use them, that if I loaded a saved route on top of an offline map, it would crash immediately.. On my first walk I had to abandon the app altogether and use a paper map. Later I discovered I could use the app if I loaded the map I needed for the upcoming walk using wifi in my hotel. As long as I didn't save it, it would persist in cache and I could load saved routes on top of it. So I finished the trip using the App that way. That's why a 2* rating. When I contacted customer support after my trip to report the problem, they admitted this was a known bug if you save more than "3 or 4" offline maps.

Really useful

I got this app just before starting out on a week-long walking holiday and was a little unsure about it as I love paper maps . It was incredibly useful. As we walked in the rain and on top of windy cliffs it was much easier to use the app than do battle with a paper map. It can be used offline so internet connection isn't vital. The image quality is excellent. It doesn't get blurry when you zoom in or out. I like the feature that shows you exactly where you are and that you can record your routes and distances. The only slight issue I have with it is if you have it set to record your route and then try to move the map to see where you are heading (or zoom out) the map automatically centres back on your current location. But all in all a great addition to the OS range.
