Nummeric is a calculator that grows with what you're doing. Start with a clean four-function keypad. Slide out the scientific panel when you need it. Switch to RPN if that's how you think. Then there's everything else. 214 SPECIALTY CALCULATORS Mortgage, auto loan, refinance, APR, income tax, take-home pay, BMI, TDEE, one-rep max, percentage, quadratic formula, concrete, roofing, tile — and two hundred more. Search by name. Each one shows the formula it uses and cites its source. GRAPHING Plot up to 10 equations at once. Pan, zoom, and trace with your finger. Find roots, intersections, maxima and minima. Share a graph as an image, or as a link that reopens the exact plot on someone else's iPhone. STEP-BY-STEP SOLVER See the working, not just the answer. Quadratics solve three ways — the formula, factoring, and completing the square — and switching methods rebuilds every step. UNIT CONVERTER 19 categories, from length and weight to torque, density and fuel economy. Currency rates come from a free, ECB-derived source and are cached so they still work offline. NOTEBOOK Write math the way you'd write it on paper. "5 ft + 3 in in cm" works. So does "20% of 150", and a "subtotal = 42.50" you can refer to on the next line. MORE TOOLS Matrices, base conversion for programmers, tip and split, sales tax, VAT, statistics, and date and time math. ON EVERY DEVICE iPhone, iPad, Mac, Apple Watch and Apple Vision Pro. Home Screen and Lock Screen widgets, a custom keyboard that calculates without leaving the app you're in, and a calculator inside Messages. BUILT TO BE TRUSTED Nine deep audit passes went into this release, backed by more than 1,100 automated tests. Full VoiceOver support, Dynamic Type, and contrast-checked colors in all eight themes. NO SUBSCRIPTION One purchase. No subscriptions, no in-app purchases, no ads. Your calculations stay on your device unless you turn on iCloud sync.
