I'm not that great at explaining things but, i'll give it a shot.
There are layers that can be turned on and off within the app. Private land, public land, hunt zones, USFS motor vehicle use, trails, roadless areas, current wildfires and historic wildfires to name a few.
If you turn the private land layer on before downloading the map, it will have property boundaries clearly laid out on that map.
Even with your phone on airplane mode or when your without cell service, your phones GPS is on and locating your position. I have found it to VERY accurate!
