Your money, in a notebook that syncs.
My Passbook is an offline-first personal ledger. It feels like a paper passbook, works with no connection, and quietly backs itself up when you add an account.

Works offline, always
Every entry is written to your device first. No signal, no problem — the ledger is fully usable on a plane or in a basement, and syncs when you reconnect.
No sign-up wall
Open the app and start recording. Your data lives on the device from the first tap. Add an account later, only if you want a cloud backup and sync across devices.
Accounts and transfers
Track cash, bank, and card balances separately. Move money between them with transfers that never distort your income or expense totals.
Debts and IOUs
Record money friends owe you and money you owe, with partial repayments over time. Lending and repaying move the right account balance but never count as income or expense.
Budgets and reports
Set monthly category caps and see where the month is heading. Trends, category breakdowns, and flow charts over any date range.
Private by design
No ads, no third-party trackers. Your ledger is yours: guest data stays on the device, and a synced account is protected by row-level security. Optional biometric app lock.
