Tools for making relatively simple graphical images


New member
As a mobile app developer, I frequently do a lot of my own basic graphics for game. Either I'm creating something from scratch (such as a button design) or sometimes I will need to modify relative simple art I've found on the web that is either labeled free for commercial use or for which I've paid a small fee.

I use Gimp a lot, but perhaps that is because I have a lot of history with it. I'm mostly on a Mac, so I've wondered if something like Pixelmator Pro would be better for me in the long run. I do use some of the Adobe tools such as Photoshop, but they are fairly expensive to license and not really a direct match for the sort of things I usually do.

What are the rest of you finding effective?
