...personally, I still think it would be cool if there was an ATP/PlantStep affiliation. It's been suggested that PlantStep is considered a competitor, but that wasn't elaborated on. I haven't delved into everything on PlantStep yet, but to me, it seems like the two could dovetail nicely without getting into each other's way. Maybe?...
I use both and they have very separate functions to me; but, again, I haven't delved into everything on PlantStep yet.
