A large-type check register with two always-visible balances: what you entered, and what has cleared. One-tap clearing, CSV export, backups to Files. Buy once, own it.
Quillbook is a check register you keep in your pocket. Enter checks, deposits, withdrawals, and fees; mark each one cleared when it shows up at the bank; and see two balances at all times — what your register says, and what has actually cleared.
Made for people who want a simple, readable, trustworthy record:
• LARGE, CLEAR TYPE — big numbers, high contrast, and full Dynamic Type support.
• TWO BALANCES, ALWAYS — your register balance and your cleared balance, side by side.
• ONE-TAP CLEARING — tap the checkmark when an item clears. Pending items stay visible.
• CHECK NUMBERS — automatic numbering for checks, with a warning on duplicates.
• SEARCH AND FILTER — find entries by payee, type, or pending/cleared status.
• BACKUP AND RECOVERY CENTER — every save is atomic and checksummed, and the app keeps redundant snapshots on your device. Back up your full ledger to Files anytime, and restore from a backup with a clear preview first.
• CSV EXPORT — your records are always yours. Export any account as a spreadsheet-ready CSV file, free of charge.
• PRIVATE BY DESIGN — no sign-up, no bank connection, no ads, no tracking. Quillbook never connects to the internet; your records stay on your device.
The free version includes one account with every feature above. Quillbook Pro — a single one-time purchase, not a subscription — unlocks multiple accounts at the same time.
Quillbook is a personal record-keeping tool. It does not connect to your bank and does not provide financial advice. Balances reflect what you enter.
