I'm learning to use "Toon Squid" to do animation on my iPad. It's a paid program for $10, no adds, very clean and intuitive. I'm enjoying it, but before I get too deep in I thought I'd ask what ya'll like for drawing on a tablet and doing simple amateur animations.
Toon Squid is very drawing focused, not as good for making sprites and using them like puppets. Which is something I'd like to try for some of my ideas.
I cannot tolerate an app that requires a subscription or that has ads.
