I have krita and some say that the animating software it has is nicer and easier than photoshop. Krita is also completely free

I haven't tried anything besides photoshop for animation, but I've heard good things about Krita (might try it out soon). Also, I'm not sure if people use it or if it exists, GIMP could be an option too, I think? I'm pretty sure animation was on there LOL. 

@Mushuk I actually didn't know that ! I absolutely hate photoshop, I just don't like the set up, I feel like there's just too much to take in. I'm used to simpler layouts like Sai, where everything is simple and clean. I phrase people who can draw on photoshop and on top of it animate. But I don't feel like paying a monthly fee for photoshop now so RIP animations. 

@Baah Yeah, I used to animate with GIMP but it's horrid. It crashes and lags, I've always had problems with it. I'm definitely giving Krita a shot and I suggest you do also ! :)
