## What is 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.
