Here's an updated video:
For those with limited data plans who don't want to watch the video, the main things that are probably helpful for you are:
- Map overlays (icon at top right in app) for BLM, USFS, cell coverage (Verizon, AT&T, T-Mobile, Sprint). I think the only other ways to get these on mobile are in apps that aren't free
- Campgrounds show by default, but you can also show overnight locations (Walmart, Rest Area, etc...), low clearance locations, and facilities (dump stations, groceries, etc...) by tapping on the search bar at the top of the app
- Offline mode (open the navigation menu with the icon at the top left, then go to "Offline Mode"). You can enable that, record any data you want to record (zoom in on different places, etc...) and it'll save it locally to your phone or computer, whichever you're on
