MSRX AI Calculator

MSRX AI Calculator answers everyday maths the way you would ask it out loud, and shows you how it got there.

Type or dictate a question — "split an 84.50 bill with a 20% tip between three", "30% off 149", "add 8.5% tax to 60", "12 km to miles", "300000 loan at 6.5% over 25 years". You get the number, a plain-English answer, and the working, so you can check it rather than trust it.

EXACT BY DESIGN
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.

A TAPE, NOT A BOX
The display keeps the roll. Recent calculations sit above the current line, ruled off like a printing calculator, and any of them can be tapped to reuse. Select several in History to read their running total, or export the roll as a PDF.

A PROPER CALCULATOR UNDERNEATH
• Standard and scientific keypads
• Trigonometry in degrees or radians, inverse and hyperbolic functions
• Logarithms, roots, powers, factorials, brackets and constants
• Memory keys, a reusable last answer, and live results as you type
• Full hardware keyboard support on iPad

NAME THE FIGURES YOU REUSE
Type tax = 8.5 once, then use "tax" in any calculation. Change it and every expression that reads it follows.

CONVERTER
Length, mass, temperature, volume, area, speed, time, data, angle — and currency, using daily reference rates, with the source and publication date always on screen.

ASK FROM ANYWHERE
Siri, Spotlight and Shortcuts answer without opening the app. A widget keeps the last result on your Home or Lock Screen, and a Control Centre button opens the calculator ready for a question.

HISTORY THAT REMEMBERS
Every calculation and answer is kept, searchable and pinnable. Tap any entry to load it back into the keypad.

PRIVATE BY DEFAULT
No account, no sign-up, no advertising, no analytics, no tracking. Your keypad calculations, named values and history are local to your device. Newer Phones answer plain-language questions on-device too. On older Phones a built-in offline solver handles the everyday ones, and only the questions it cannot parse are sent — as text alone, with no identity attached — to an AI service to be answered.
