I was using All Trails and switched to Gia
Hiking Trail Maps, Hunting Units, 4x4 Offroad App | Gaia GPS
It has a subscription and is more of an interactive map tool for sharing info and recording routes than All Trails.
You can download trails of other users to see where they went to verify the trail etc.
I drop waypoints all the time for possible future camping spots and trail notes. It synchs to my account and I can see it on my phone and when I get back to the PC to plan my next route.
There are a lot of threads on mapping tools around the forum.
