BillPlex is the private money tracker for two — or the whole household. Split the bills, track what comes in, and see who owes who — without an account, a bank login, or anything ever leaving your phones. Partners, roommates, or a whole household: one home, three different memories of who paid for the groceries. BillPlex ends the argument. Who paid for what, settled in seconds Assign every expense to a person, see exactly who owes who, and settle up in seconds — not on the back of an envelope. Your personal coffee stays yours and the shared groceries stay shared, so your morning latte never blows up the joint budget. No account. No bank login. No cloud for your money. No sign-up wall, no email, no password to forget — install, open, and start in five seconds. When you sync, it happens directly between your phones over your own Wi-Fi: someone adds the supermarket run while you're still at the till, and it lands on everyone's screen before you finish bagging. Even your safety net stays yours: switch on automatic backup and BillPlex quietly keeps an encrypted copy up to date in a spot you choose, locked with your password. Your expenses never touch a cloud. Now it counts what comes in, too Log your income next to your spending and BillPlex shows the whole picture — money in, money out, and what's actually left. It's your own private household money manager, minus the bank logins: a real view of where your money goes and where it stands. Just you? That works too No one to split with?
