The problem

Keeping track of your own spending and splitting shared bills usually means a spreadsheet or several separate apps.

What I built

A web app that installs on a phone and works offline. It tracks expenses, splits bills in groups, sets budgets and charts your spending. An AI assistant answers questions like how much you spent on food this month, and it can add or change expenses, but only after you confirm.
