for iPhone
A calculator that works like a receipt.
Every number stays on the tape, so you can see, fix and share the whole calculation, not just the answer.

Numbers first, names later
Type amounts on a big, clear keypad and watch the running total. Tap any line afterwards to name it, or tap its amount to change it. Everything below updates instantly.
Everyday tools
Tip, split the bill, discount, % of, % change, what %, rule of 3, unit price and average, each added as a clear line so you can see where every number came from.
Share the receipt
Send a clean picture of the tape to Messages or WhatsApp, or copy it anywhere. Six receipt styles, from a classic till roll to an adder tape.
Six keypad themes
Paper, Adding machine, Minimal, Braun, One-hand and Night terminal. Light, dark or automatic, independent of your phone.
Names itself
Untitled tapes get a sensible name automatically, using Apple Intelligence on the device, on iPhones that support it.
Subtotals and blocks
Draw a subtotal under any group, close a block with a total and start the next, and get a grand total across them all.
No account, no ads, no tracking. Your tapes stay on your iPhone.
