High school student looking to build a finance project. What problems need solving?

Hey, high school student here

I am looking to build a program that solves real world finance problems people deal with

If you have run into something frustrating in areas like budgeting, investing, taxes, or tracking expenses that you could not find a good solution for, I would like to hear about it

Even small annoyances or things you feel should exist but do not would be very helpful

Appreciate any input
