Multi vs SepCalc

Multi-Stopwatch extends your normal stopwatch with many useful additional functions. Multiple stopwatches • Stop several times simultaneously • Use the 2 modes "Normal" and "Sprint". In "Normal" mode the stopwatches run in parallel. In "Switch" mode only one stopwatch runs at a time. If another stopwatch is started, the previous one pauses automatically. Sprint Mode • You want to track many runners, swimmers? Then the sprint mode is perfect for you • The large buttons and the haptic feedback help to operate without having to look at the iPhone Platforms • In addition to the iPhone app, Multi-Stopwatch is now also optimized for your iPad • Use Multi-Stopwatch now on your Apple Watch Customizability • Adjust the multi-stopwatch exactly to your needs • Need a bigger toolbar? Do you want the times to be displayed to the nearest second? You can set it now • You want to show the number of rounds and the last round, hide the name for it? You can set it now • When you tap on the stopwatch, you don't want to stop the time but see details? You can set it now Of course, the stopwatches also run in the background with millisecond accuracy. Perfect e.g. for sports teachers, doctors, time recording, DLRG, races and much more.

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.
