MSRX AI Calculator
On-device AI. Exact answers.
Free · Designed for iPad. Not verified for macOS.
Ask in plain words, get the exact number. A tip split lands on 28.32, never a plausible 28.30 — and every answer shows the working behind it.
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.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
A complete rebuild, and a new name: Numly is now MSRX AI Calculator.
THE DISPLAY IS NOW A TAPE
Recent calculations stay visible above the current line, ruled off like a printing calculator. Tap any of them to reuse the result.
FASTER, AND OFFLINE MORE OFTEN
Newer Phones answer plain-language questions entirely on-device. Older Phones answer the everyday ones offline too, and fall back to an AI service only for the rest. You never have to choose or set anything.
A NEW CALCULATION ENGINE
Division, precedence, brackets and roots are now exact, and malformed input reports a clear error instead of failing quietly.
ALSO NEW
• Running totals — select lines in History and read their sum
• Named values — type tax = 8.5 once, use it everywhere
• Currency conversion with the rate source and date always shown
• Export your tape as a PDF
• Siri, Spotlight and Shortcuts support
• Home Screen and Lock Screen widgets, and a Control Centre button
• Full hardware keyboard support on iPad
• Dictate a question instead of typing it
• Redesigned throughout, in light and dark
Every answer can still show its working.
