Too bad, maps.me was by far the best maps application for non city use, and ideal for hiking. Commendable initiative to bring it back in its original version! A few examples of why it was so great: Simple, non social bookmarks. As in: place a bookmark so you don't get lost while hiking, or when you find a nice spot you want to come back to later. Yep, a utility feature that doesn't somehow map to some stoopid busines…
They are great for cycling and hiking. Setup is a bit more involved compared to maps.me, because you need a separate maps viewer app. Overall nothing too complicated for a somewhat tech savvy audience though.
My mapping app of choice is locus maps. There are alternatives such as OruxMaps available too.
