SepCalc

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. From a quick calculation to an advanced model, SepCalc keeps powerful tools organized, discoverable, and ready when you need them.
