I use Spyglass app for navigating in the woods. It allows to save a needed map area in the cache and use it later even without internet, though it's not a large area. The big plus of this app is the possibility to save several waypoints and spots: I usually mark hunting stands and my car location with it. And you can also send your location for your pals.
OnX Hunt is also pretty cool, it shows private areas and land owners names.
