Great map tool
My go to mapping app; I love it. I use it for reference and browsing, and in the air; I do not hike with it. Features that I particularly like:
Works with external GPS (Dual)
Imports/exports gpx files
Shows track statistics
Easy to switch between multiple really cool base maps (historic, satellite image, VFR charts)
Download maps so you dont need a network
There are some interface issues, particularly with saving tracks and arranging them in folders, that are not obvious and that I have not pursued.
