Budget Binder

Budget Binder is envelope budgeting the way your grandmother did it — every dollar goes into an envelope before you spend it. That's the whole trick, and it works entirely on your phone with no account, no sign-in, and no internet required.

GIVE EVERY DOLLAR A JOB
When money comes in, it lands in "Left to budget." From there you fill your envelopes — Rent, Groceries, Gas, Eating out — until every dollar has a job. Spend from an envelope and you always know exactly what's left. When an envelope is empty, it's empty. That's the point.

BUILT FOR REAL PAYCHECKS
Paid biweekly? Twice a month? Irregular hours or 1099 income? Budget Binder works off the money you actually have, not a forecast. Fund your envelopes when the check lands, and stretch what's left until the next one.

YOUR MONTHLY WORKSHEET
Filling envelopes at the start of each month takes seconds: set a plan for each envelope once, then fill everything to plan with one tap. Leftovers roll over, so an unspent grocery run in May is still yours in June.

SINKING FUNDS
Saving toward car repairs, insurance premiums, the holidays, or back-to-school? Sinking funds save up month after month toward a goal, and show you exactly how far along you are.

BILLS THAT DON'T SNEAK UP
Add the bills you pay every month with their due dates — rent, utilities, car insurance, phone. Budget Binder shows what's due, what's paid, and pays each bill straight from its envelope with one tap.

EVERY CHANGE CAN BE UNDONE
Every fill, expense, and edit shows up in History — and any of it can be undone with one tap, even days later. Fat-finger a transaction? Undo it. Change your mind? Put it back.
