Nummeric vs SepCalc

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.

ONE CALCULATOR. EVERY LEVEL OF WORK. SepCalc combines an approachable everyday calculator with the depth of a professional scientific, graphing, programmable, and financial workstation. Start with a simple expression, then turn the result into an explanation, graph, table, scenario, script, or auditable report. FAST, FLEXIBLE CALCULATION • Natural algebraic entry and optional RPN • Exact fractions, radicals, symbolic constants, complex numbers, and arbitrary-size integers • Scientific, engineering, fixed-decimal, fraction, and mixed-number formats • Degrees, radians, gradians, DMS, bases, bitwise operations, variables, memory, and searchable history • Clear calculation steps, domain checks, precision controls, and reusable results SCIENTIFIC POWER • Computer algebra for simplifying, expanding, factoring, solving, symbolic calculus, series, and transforms • Numerical solvers, derivatives, integrals, optimization, differential equations, and error estimates • Vectors, matrices, linear systems, decompositions, eigenvalues, and least-squares analysis • Dimension-aware unit conversion and searchable physical constants with source metadata • Engineering, electrical, chemistry, geometry, and measurement tools GRAPH, VISUALIZE, AND EXPLORE • Cartesian, polar, parametric, implicit, inequality, sequence, and field plots • Trace roots, extrema, intersections, derivatives, tangents, and areas • Linked value tables, parameter sliders, animation, and adaptive discontinuity handling • Interactive 3D surfaces, curves, vectors, meshes, cross-sections, contours, and exports DATA AND STATISTICS • Typed tables with CSV and TSV import and export • Descriptive statistics, probability distributions, regression, inference, and ANOVA • Statistical plots, time-series tools, simulation, bootstrap, permutation, and Monte Carlo workflows • Optional permission-based sensor and laboratory data capture with provenance A FINANCIAL CALCULATOR BUILT FOR REAL DECISIONS • Complete TVM worksheets for N, I/Y, PV, PMT, and FV • Loans, mortgages, amortization schedules, refinance comparisons, and savings goals • Cash flows, NPV, IRR, capital budgeting, interest conversion, depreciation, dates, profit, and breakeven • Bond pricing and yield, portfolio performance and optimization, valuation and DCF • Options, Greeks, risk analytics, historical source-aware FX, and actuarial tools • Visible formulas, substitutions, timelines, assumptions, day-count conventions, and sign conventions PROGRAM IT YOUR WAY Use the bundled offline Python environment for scripts, notebook-style work, native math and finance APIs, charts, reusable projects, and custom calculators—without depending on a Mac, external Python installation, or network service. DESIGNED FOR TRUST SepCalc uses deterministic engines to calculate and verify results. Guided tools can help interpret a problem, but the mathematics remains inspectable. Core math, finance, graphing, and scripting work locally. Your projects stay under your control. Built for iPhone and iPad, with a capable Apple Watch companion, widgets, Shortcuts, sharing, accessibility support, and localized experiences in English, German, French, Spanish, Brazilian Portuguese, and Japanese. From a quick calculation to an advanced model, SepCalc keeps powerful tools organized, discoverable, and ready when you need them.
