Budgeting apps have optimised for the wrong thing for 10 years and nobody talks about it

Every major budgeting app — YNAB, Copilot, Emma, Monarch — has spent a decade competing on design, bank integrations, and chart types. They have all missed the actual problem.

The reason people fail at budgeting is not that they cannot see their spending. It is that seeing it does not tell you what to do, and doing it alone is harder than doing it together.

Every single one of these apps is built for one person making all the financial decisions in isolation. The moment a second person enters the picture — a partner, a co-parent, anyone — the system breaks. You end up texting screenshots of your budget to someone who does not have the app open.

And none of them act. They record, categorise, and display. Then they wait for you to figure out the next move. An AI that can only answer questions is just a fancier chart.

The whole category is a passive dashboard dressed up as a financial tool. I think that is about to change.

What do you think is the biggest unsolved problem in personal finance software right now?
