Last week, signed up for onXmaps for Tennessee. Looked at local WMAs and recognized several names on bordering property. Looking forward to using it to spot private property that might be available and the boundaries of the WMAs.
I've used Onx for a few years, its solid. No real draw backs except the price if you choose to upgrade your membership.
The app is worth it - if you need to renew, they usually have a good deal on Black Friday/Cyber Monday.
Best deal I've found, seems to be on camofire. Usually about every other week it runs for (I think) 17.99 for single state and 59.99 annual for all states.
One additional, they made several changes, which included redownloading all your offline maps in Aug/Sep... Not a big deal for most whitetail hunters, but a big deal for folks hunting AK/Western states... Fortunately, I was able to update all my offline maps just before leaving for Colorado.
