The road to disappointment is housed in your phone's default or other free map apps. Those are ok for getting around cities (sometimes) but absolutely worthless once on a gravel road. I've tended to rely on memory and a sense of exploration for traversing trails on either motorcycle, atv, or 4x4. This meant that I stuck close to the area I was intimately familiar with or depended on others who knew the area.
The one thing I do not want to do is cross onto private land or travel on an unapproved road. I also would like to see more of my beautiful state. As I looked into various map apps, the onX app appealed to me because of its simple interface and their reputation in the navigation industry for accuracy.
With that in mind, I signed up and have been very happy with my experience so far. I've saved a good deal of the area I am likely to frequent so I can access those maps off-line. So long as I've got juice in the phone's battery, I'm good to go off the road. So far I've used the onX map app to locate and ride 4 "new' trials within 30 minutes of my house. I am ready to get out this fall to see much more!

The app can save your map in a very high-resolution format for off-line navigaton. One downside is that longer "blue" trails can't be saved as one map. The Blue trails have uses photos and trail ratings so you don't get in over your head, so to speak.
One of the most useful features of the onX app is the suggested trails. This pulls in your location and routes close to you. Very useful for gaining access to new trails!
