The 1:25k scale is essential for walkers and the ability to create a route at home or to log it (recording your time & distance etc) as you go along is superb. I like the direction indicator to show where you are heading on the map, the ability to save, describe and name tracks is neat. It's easy to slide the map about from your current position to see where you are heading next, the zooming in and out facility is good. I found it reasonably easy to learn how to use.""This is not a cheap navigation program, it is a professional tool for viewing raster maps. And for this purpose, it is excellent. For viewing topo maps, this is the best software and hardware combination for the job, this alone was my reason to get an Android tablet, and it was the right decision.""The Memory-Map App is a truly excellent, competent product, representing real value for money. It's straightforward to use, with just enough preference settings and options to describe it as customizable. Route-creation and route-following are ridiculously easy to set up, yet provide a tremendous range of route data. You can also import and export GPX files (via email). A really strong product at this price point." Andrew Knight, Yacht Arabella blog"After buying about 6 navigational applications for my tablet I finally got one that really works the way it should. I now have a handheld version of my sailboat's navigation system. I am very happy with this app and would recommend it to any avid sailor"
