For me onX seems to work amazingly well everywhere but in the woods.
Slow to bring up the info and seems to eat my battery even on airplane mode. I don't understand that, but it's not my imagination. As such I only spot use it, turn it on, check my location and turn it off. Even just doing that I get about half a day at most.
The property line info doesn't show when I'm using my off grid maps (for whatever reason, maybe I'm doing something wrong, I dunno), in which case is it's no better than the other free apps I already have on my phone.
Their 'by signing up you automatically agree to automatic renewals" thing really turned me off as well. This year may be my last year.
