The mobile spreadsheet problem is definitely a hurdle, I think finance quizzes would be great to have on the go as a supplemental education piece.

Breaking down the formulas that work in certain situations or how certain modeling strategies are implemented conceptually could also lend well to a mobile platform without also requiring a “mobile spreadsheet” approach, which in all honesty sounds like a nightmare development process.

Either way, love the platform and wishing you all the best!
