OK, but useless for learning – Math Ref Review

It's just an organized collection of formulas. If you keep encountering hard to understand mathematical concepts explained in impenetrably arcane mathematical jibber-jabber, look elsewhere. This app is for those who already have a deep understanding of mathematics. Just once, I'd like to see an app writer come up with one that lets the rest of us on board by explaining concepts in plain language, using analogies, animations or whatever else it takes to help the rest of us break through.
