Splitting one bill is easy. Remembering who owes you across last month's dinners, the beach trip, and rent — that's Just Split. On iPhone Duo, unfold it and the bill sits on one page with the people who shared it on the other. Every bill you split feeds a running ledger: open the People tab and see exactly where you stand with each person, across everything. Settle up in one tap — a single Venmo or Cash App request for the net amount, with an itemized note listing every bill it covers. Record cash payments, and the balance updates. No accounts, no spreadsheet, no "wait, didn't you get the last one?" And before anyone pays, Just Split checks the restaurant's math. WHY JUST SPLIT IS DIFFERENT • THE LEDGER — Running balances per person across every bill. "Sarah owes you $63 · 4 bills." One tap settles all of it. • RECURRING SPLITS — Rent, utilities, streaming: set it once and it lands on everyone's ledger every month, automatically. • THE BILL AUDIT — Just Split checks the restaurant's math. Double tips (a printed gratuity plus a tip on top), wrong totals, duplicate charges — caught before you pay, with a running total of what the Bill Guardian has caught for you. • WORKS WITH EVERYONE — Venmo, Cash App, or text. Friends claim their own items from a link in any browser — Android friends included, no app, no account. • EXACT TO THE PENNY — Every person's share adds up to exactly the bill total. No vanishing cents. Discounts and voided items count too.
