RPN Deck is a reverse Polish calculator built for speed — and for fixing mistakes without starting over. EVERY NUMBER STAYS EDITABLE On most calculators one wrong digit means clearing the lot and typing it again. Here every value stays on screen. Tap a row to correct it in place. Swipe a row away to delete it. Undo steps back through anything you did. RPN, PROPERLY Type a value, press ENTER, type the next one. No parentheses. No equals key. No expression to hold in your head and get wrong three terms later. The stack is unlimited and every level of it stays visible. FAST Four functions and a percent key. TOTAL folds the whole stack into one number in a single press. Nothing is buried in a menu, because there are no menus. THE FULL DECK — a one-time in-app purchase Three ways in, one unlock. The Tape prints every keystroke like a receipt — each entry, each operation, each total — and shares as an image, text, or PDF. Scan points the camera at a receipt so you tap printed amounts straight onto the stack. Voice lets you speak numbers and they land where you'd type them. Family Sharing is supported, so one purchase covers your family group. SIMPLE ON PURPOSE No scientific functions. One surface, and everything on it does something. PRIVATE BY DEFAULT No account. No sign-in. No analytics, no tracking, no advertising. Nothing leaves your phone unless you share it yourself. iPhone, portrait, English.
