DiamMath

DiamMath plots, calculates and explains – for school, university and work. Type a function the way it looks in your notebook, and DiamMath typesets it, draws the graph, finds roots, extrema and intersections, differentiates and integrates – and double-checks every result. No account, no ads, no internet connection required. BUY ONCE, USE FOREVER DiamMath Basic is free forever. DiamMath Pro can be tried free for 14 days and then unlocks everything with a single one-time purchase – no subscription, no hidden costs, no ads. The trial ends on its own and nothing is charged – once per Apple ID, on iPhone, iPad and Mac. TYPE IT LIKE YOU WRITE IT • School notation without multiplication signs: “2x”, “ax”, “2πr” and “x(x+1)” are read correctly • A dedicated math keyboard with two pages – digits and variables, and with a swipe sin, cos, tan, ln, log and more; DiamMath adds the closing parenthesis when you confirm • Clean typesetting for every input, and errors with a clear hint instead of a silent gap PLOT • 2D graph with several functions, parameter sliders, zoom and crosshair • Sideways curves, circles and inequalities as shaded regions • Functions with the imaginary unit i: real and imaginary part as two lines • Special points – roots, extrema, inflection points and intersections –, derivative curves, area between curves, value table and export as image, PDF and spreadsheet (Pro) • 3D graph for height surfaces and solids such as a sphere or a heart – rotate and zoom (Pro) CALCULUS (PRO) • Derivatives up to third order, symbolic and with a numerical check • Definite integrals with the school method wherever a school rule applies • Roots in an interval and limits • Calculating with complex numbers CALCULATE AND LOOK UP • Scientific calculator with history, degrees and radians • Systems of equations with up to three unknowns and a verified solution path • Formula collection with 119 formulas from algebra, geometry, calculus, statistics and physics up to electrical and heating engineering – 97 of them with a derivation • Advanced workshop for the complex plane, matrices, sequences, statistics and units; visualization workshop for polar, parametric and implicit curves and geometry (Pro) SCAN • Function scanner: photograph a handwritten or printed function – DiamMath reads it and sends it to the graph or to calculus. Recognition runs entirely on the device. YOUR DATA • DiamMath collects no data, has no tracking and needs no servers of its own • Workbooks with as many sheets as you like, a trash instead of permanent deletion • iCloud sync between iPhone, iPad and Mac only if you want it, through your personal iCloud • Export and restore backups (Pro) • App design, accent colors, background images and 24 app icons in six gemstone colors BASIC AND PRO IN DETAIL Basic includes functions and the 2D graph, the math keyboard, the calculator, systems of equations, the formula collection, the function scanner, iCloud and app design. Pro adds the analysis tools in the 2D graph, calculus, the 3D graph, both workshops and backups – without limits. DiamMath is available in English and German. Numerical approximations are labelled as such in the app.
