Your checkbook register, exactly as you remember it. Simple Register brings the familiar paper checkbook register to your Apple devices. Open it, enter a transaction, see your balance, and close it. No bank connections, no complicated budgeting system, and no subscription. TRY IT FREE FOR 7 DAYS New customers can start a seven-day free trial with every feature. After the trial, unlock permanently with one purchase: US $9.99, with local pricing shown in the app. There is no subscription or automatic charge. Your existing records stay available to read and export after the trial. Customers who already own the paid app keep full access at no additional charge. FAST, FAMILIAR ENTRY • Record payments, deposits, checks, and transfers • Type 1254 and Simple Register enters $12.54 • A type-ahead payee list as you type, built from your own history • Save an entry and immediately add another • See your running and cleared balances at a glance • Move an entry to a different register when it landed in the wrong one RECONCILE WITH CONFIDENCE Enter your statement balance, check off cleared transactions, and watch the difference reach zero. Simple Register never changes your transaction amounts just from checking them off. Found something you forgot to enter, or a mistyped amount, while matching your statement? Add or fix it without losing your place — and if you need to step away, your checked items and statement amount are still there when you come back. SCHEDULED, ON ONE CALENDAR Set up anything that repeats — a paycheck, the mortgage, a bill whose exact amount isn't known yet — and see every register's upcoming entries on one monthly calendar. An entry that should post itself does; one you'd rather confirm yourself shows as a reminder until you say it's handled, or until a matching payment checks it off on its own. BIG ORDERS, HANDLED Enter a large order once at its full total — even if the bank bills it as several separate charges. List each charge under the entry as it posts, check them off one by one, and reconcile against your statement exactly the way the bank sees it. MADE FOR HOUSEHOLDS Keep as many registers as your household needs — checking, savings, a credit card, vacation fund, gift money — each with its own column labels so a savings register and a card balance never look like a checkbook. Transfers record both sides automatically and stay linked, and every entry shows who added it. YOUR REGISTER, YOUR STYLE Choose from familiar checkbook-inspired covers and ledger styles while keeping every number clear and readable. PRIVATE BY DESIGN • No bank logins • No Plaid or financial account linking • No ads • No analytics • No Simple Register account • Optional local-only mode • Optional Face ID, Touch ID, or passcode protection YOUR DATA STAYS USEFUL Export your register to CSV or PDF whenever you need it. Edit history and Recently Deleted help protect you from mistakes. BUILT FOR APPLE DEVICES Use Simple Register on iPhone, iPad, and Mac, with your private iCloud keeping your registers in step across your devices. Simple Register is for people who want to track their money themselves — without handing their financial history to another service. If you'd like to support development, an entirely optional one-time tip is available from Settings & Privacy — it never changes what the app unlocks.
