I am going to have a look at OnX. I usually start with OpenStreetMap or OpenTopoMap to make a track and then check it against Google Maps or National Geographic maps for sanity. Those tools don’t show where a track crosses into private property very well though. For example a couple of years ago I created a track through the Pine Nuts, but the apps I used did not show that the track crossed tribal land. We had to turn back when we reached a locked gate with a warning sign. A tribe member was there and said their private land was visible on the “HunterX” app, which I could not find. Maybe he meant OnX.
