I'm in the same boat as AWS. I much prefer my now aging TraxWEST for seeing landownership, so I still use that in the truck GPS. However, it's starting to get outdated so I also use onX Hunt on my phone and PC to confirm and for use in the field when I forget to move the Kirsch chip over to my handheld Garmin. I suppose it's only as accurate as the GPS receiver in the phone, but I have seen the jumping around that Longcruise mentions. I hunt in a lot of areas that don't have good cell reception, so I have to download offline maps for onX, which eats up memory on the phone. And if I step outside those downloaded areas, I'm hosed. So, overall, it's not perfect, but it works well enough that I resubscribed this year.
