I've been using maps.me for a long time for offline map use while hiking and traveling off the grid, but recently switched to organic maps due to their superior interface. They both use openstreetmaps, which I have found to be outstanding. Even the most obscure trails and overgrown overlanding tracks are almost always on openstreetmaps. The file sizes are quite small, and being able to download specific areas, or states, or entire countries at a time is perfect. I prefer organic maps to alltrails, gaia maps, etc. It's become an indispensable tool for me while hiking and traveling.
