It's a great app with great support (as you can see by the developer's presence here). It doesn't give enough info yet when you're completely offline, but it's getting there. I suggested that the GPS info be available offline so you could cut and paste or even manually enter it into another app since many of us use apps that allow map caching for offline use. But I found I used the app most often before I plunged into the backcountry (if you're outta cell range usually hunting for designated campsites isn't what you need this app for). Being able to open the campsite in Motion X or Gaia as a WAYPOINT would be a very cool idea, even offline. Right now it's great because you can open the campsite as a destination in Motion X Drive or Google or Apple map apps. You could save the campsite location in Drive and then predownload some maps for offline use, although that isn't my fav app for offroad use. Saving the location in Apple or Google Map apps was beyond me, although maybe there's a way.
The inclusion of dispersed areas is helpful as well. I realize that includes most USFS and BLM land here in the west, but when you're tired of driving and in one of those checkerboard areas where you're not sure if it's OK to boonie it's quite helpful.
And the info about showers and elevation is really useful. I wish the Benchmark atlases had that, but they don't include elevation. Again here in the west a few miles can make a big difference and although a topo map might give you the same info it's helpful in a list. Be nice if you could sort the list in the search view by criteria, like >3500'. Or at least by feature like "shower" or "flush."
It doesn't do private campgrounds, but there are other apps for that, and they usually make themselves more available. And it's pretty up to date here in the west. I've been trying to stump them, but haven't found any they don't list.
Since our fed gov't is folding like a cheap tent, it was useful that in the app you can select what agencies to search, so you could turn off BLM, USFS, NPS and just get state, county or utility campgrounds.
Well worth the money IMHO, and looks to be an app that will improve over time.
