A tape calculator that doesn't forget. Every number you tap goes onto a tape you can scroll, edit, save, and come back to. No more wiping the screen by accident and losing the whole calculation. No more squinting at one line of digits, trying to remember what you were even working on. DIGITCA is built around a simple idea: numbers deserve a paper trail. The tape isn't just a log. It's the calculator itself. Tap any number to change it on the spot and watch the totals update live. Strike a row out like a pencil would. Undo anything: a deleted row, an edit, even a cleared tape, with a button, a shake, or a three-finger swipe. Autosave keeps your work safe between sessions. FREE Full tape calculator: persistent, scrollable, autosaved, with full undo Editable tape: tap any number to change it and totals recalculate instantly Tape order your way: authentic (newest at the bottom) or modern Cashier mode for quick running totals Scientific keyboard: trig, log, factorial, combinations, permutations, scientific notation, and statistics computed over your actual tape Natural input: type or dictate "twelve fifty plus tax" and DIGITCA gets it.
