Budgeting apps track what you spend and call the leftovers savings: for most people that's zero. Basis flips it. Your saving rate comes off the top on payday, like a bill. Budget the rest across your own categories, and close each month yourself: every overspend forces a decision (cover it from savings, or carry it forward tighter), leftovers sweep into savings. Nothing settles silently. No bank link, no account, no cloud. Free forever, no server to pay for. Built by an Italian teenager.
