Clicking that link finds tons of apps. Whether any are good, I don’t know. But I do know that those apps exist, which is what you asked. It could be that there are no good apps. I don’t know even in principle what such an app could do that was useful.
By contrast, I’ve heard lots of good things about Khan Academy videos. You might try a few of those instead of an app. Ideally, work with a human tutor as well. I’ve tutored calculus, everyone has their own stumbling blocks, and it’s best to work with someone who can see where you’re hitting trouble and help you get through it.
This looks like an ad. What’s wrong with F-droid?
