I create animations on my phone and animate in a method of sprite animation or using a sprite sheet and I take a picture of it and crop each image to turn it into a frame. I try to use measurements but from time to time the frames of the animation tend to get shaky and can be hard to focus on.

Is there any possible advice to use the sprite animation method more efficiently without having shaky frames and are there any free animation softwares on phone or mac laptop as when I create animations on my phone it only has a limit of 230 frames.

Thank You for your time
