About

MSRX AI Calculator

Features
Read full description

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. Designed and built by MSRX.
