Needing a way to track finances is a problem older than writing. It's an almost universal problem, and everyone has their own ideas on how it should be done.

It's also a complicated idea, and when you look at existing solutions, they almost always have a huge number of features that any given individual won't need, which makes it harder to figure out what you're doing.

If you have a background in programming, and none in finance, it might be easier for you to start from what you understand, and build up an app that does what you need first, then add features later as you understand the problem space more.
