Been using Callipeg: 2D Animation App for a couple months now. It’s basically a 2D animation tool for your Android device. Pretty solid app if you’re into creating cartoons or illustrations.
Here’s what you do: you can draw frame-by-frame animations, do keyframe stuff, and even make storyboards. There’s also a ton of organization features like arranging your shots, tagging them, and searching through everything. And the large canvas and adjustable frame rates are really useful.
Look, if you’re an animator or just like playing around with drawing apps, you’ll probably like this. It’s not perfect – the learning curve is a bit steep and the ads can get annoying – but overall it does the job. Worth checking out if you’re into that kind of thing.
