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. FAST, FAMILIAR ENTRY • Record payments, deposits, checks, and transfers • Type 1254 and Simple Register enters $12.54 • Reuse recent payees, with gentle reminders when a monthly bill seems due • Save an entry and immediately add another • See your running and cleared balances at a glance RECONCILE WITH CONFIDENCE Enter your statement balance, check off cleared transactions, and watch the difference reach zero. Simple Register never changes your transaction amounts during reconciliation. 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. SHARE WITH YOUR HOUSEHOLD Keep one register between two people. Invite someone from your household and you both add, edit, and reconcile the same book on your own devices. Invitations are private to the people you choose — view-only or full edit — and the data never leaves your iCloud. PLAN YOUR BILLS List your monthly bills once — due date, minimum payment, auto-pay — and check them off as you pay. A month calendar shows every due date, your register nudges you when a bill is due this week, and recording the payment checks the bill off automatically. MADE FOR HOUSEHOLDS Keep as many registers as your household needs — checking, vacation fund, gift money. 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.

PlentyBook is a checkbook register, and nothing more than that. Type an amount. Tap Income or Expense. Done — the keypad is always on screen, so adding a line takes about two seconds and never opens a single pop-up. MULTIPLE ACCOUNTS Keep a register for checking, for savings, for the cash in your pocket. Give each one a colour so you always know which book you're in at a glance. Every account is completely separate — no shared budget, no combined pot, no cross-talk. A RUNNING BALANCE ON EVERY LINE See what the balance was after each entry, the way a paper register works. Newest entries sit at the top, where you actually look. SIMPLE BY DEFAULT Out of the box there are three ideas: a starting balance, money in, and money out. Notes are optional. Categories, day grouping, and marking entries as cleared all exist — but every one of them is switched off until you decide you want it. LIGHT, OR NOT Light by default, because most checkbook apps are relentlessly dark. Flip it to Inverted if you prefer, or let it follow your system. FIND ANYTHING Search notes, amounts, or categories. Results show how many matched and what they add up to, so "how much have I spent on coffee" is one search away. QUICK AUDIT Money in, money out, and the net for this month, last month, the last 30 days, this year, or any range you pick. LOCK IT Require Face ID, Touch ID, or your passcode to open the app — or to open just one account. Off by default, and free. SYNC, IF YOU WANT IT Switch on iCloud sync and your register follows you to your other devices, through your own iCloud. It is off until you turn it on, it comes with the unlock, and you can turn it back off whenever you like. YOUR DATA IS YOURS No account. No sign-up. No email address. No analytics, no trackers, no ads. PlentyBook has no server, so your register never comes to us. It stays on your device unless you switch on iCloud sync, and then it goes to your own iCloud and your own devices. Sync is off until you turn it on, and you can turn it back off. Export a backup to a plain, readable file whenever you like. That's free, always, whether you buy anything or not. FREE, WITH ONE OPTIONAL PURCHASE PlentyBook is free with one account. A single $9.99 purchase unlocks unlimited accounts and iCloud sync — one payment, no subscription. Built by ASHA Technology LLC.
