iPhone & iPad
A calculator that answers everyday maths the way you would ask it out loud — and shows you how it got there.
The intelligence reads your question. A separate maths engine does the arithmetic. Every figure on screen comes from that engine, never from a language model guessing at digits — so a tip split lands on 28.32, not a plausible 28.30.
Every answer can show its working, so you can check it rather than trust it.
Recent calculations stay above the current line, ruled off like a printing calculator. Tap any of them to reuse.
Bills, tips, discounts, tax, percentages, interest, loan repayments and conversions.
Standard and scientific keypads, degrees or radians, memory keys, brackets, constants, live results.
Type tax = 8.5 once, then use it in any calculation. Change it and everything that reads it follows.
Nine categories of units, plus currency with the rate source and publication date always on screen.
Siri, Spotlight and Shortcuts, Home and Lock Screen widgets, a Control Centre button, and full keyboard support on iPad.
No account, no sign-up, no advertising, no analytics and no tracking. Your keypad calculations, named values and history stay on your device.
Newer iPhones answer plain-language questions on-device. Older iPhones answer the everyday ones offline too, and only questions the built-in solver cannot parse are sent — as text alone, with no identity attached — to an AI service. Read the full privacy policy.
