Procreate was the first app I started playing with. I still like the interface a lot. The tools are easy to access and the controls I want are around the edge of the canvas. It also gives me the option of working in a higher resolution, with a reasonable drop in speed.
My only complaint is I’m seeing a significant color shift from the ipad to the desktop. The colors are darker and redder. I can do some adjustment in Photoshop, but it would be nicer if I didn’t have to.
