Plott vs SnackLab

Plott is a fast, native graphing calculator for 2D and 3D — a desktop-class grapher rebuilt for touch. Plot a function, a family of curves, a polar rose or a glowing 3D surface, then pan, zoom and orbit at a silky 120fps. Everything works offline, with no account and no sign-in. Type one line and Plott works out the rest — explicit y = f(x), polar, parametric, implicit, inequalities and vectors, all classified as you type. — GRAPH ANYTHING — • Functions, piecewise, polar, parametric and complex curves • Implicit equations and shaded inequalities • Families: sweep a whole set of curves from a single line • Data tables, scatter points and best-fit regression • 3D surfaces z = f(x, y), parametric surfaces, space curves and knots • Vector fields, slope fields, differential equations and attractors • Contour lines and level-curve heat maps — MATH, BUILT IN — • Sliders: drag a parameter and watch every curve update live • Calculus: derivatives, tangents, integrals and area under a curve • Evaluate limits, sums, products, matrices and determinants • Points of interest: tap to snap to roots, intercepts, extrema and intersections • Trace any curve for a live coordinate readout — TRUE 3D — • Real surfaces you can orbit to any angle — free rotation, no gimbal lock • Pinch to zoom, drag to pan, tap to read a point in space • Isometric, top and front view presets • Smooth at 60/120fps and fully offline — MADE FOR PHONE & TABLET — • A calm, high-contrast drafting studio in two themes: a luminous blueprint dark and a warm vellum light • On tablet, a desktop-class side rail edits every object at once • A purpose-built math keyboard with templates for every curve type • Apple Pencil and hardware-keyboard friendly — YOURS, ALWAYS — • Unlimited undo/redo, autosave and session restore • Export to PNG or PDF, or share a sheet as a file • A gallery of first-party examples to learn from Plott is made for students, teachers, engineers and the mathematically curious — precalculus and calculus, algebra and geometry, statistics and beyond. Replace a clunky handheld and a pile of apps with one beautiful grapher. Graph beautifully. Download Plott.

One app for the whole span of school and university math — from quadratics to Fourier series. Write an equation on the left and it is drawn immediately on the right. Tap an intersection, an extremum or an inflection point and SnackLab gives you the exact coordinates: a fraction, a root, a multiple of π — not a rounded decimal. WHAT YOU CAN GRAPH Functions Polynomial, rational, trigonometric, exponential and logarithmic curves. Piecewise definitions, asymptotes and removable discontinuities are handled properly. Calculus Derivatives, definite-integral regions, extrema and inflection points with exact coordinates. 3D Surfaces, planes and lines, the curves where they intersect, and closed regions. Rotate and pan freely. Statistics Distributions, interval estimates, data entry and charts. Differential equations Direction fields, numerical solutions, Laplace transforms. Keep several equations and switch between them. Engineering mathematics Matrices and eigenvalues, vector calculus, Fourier series, the complex plane. BUILT FOR EXPLORING Drag a slider and watch the curve respond — coefficients, parameters and domains update live. Save a graph straight to your photo library. The keyboard is laid out for mathematics, not for text: fractions, roots, exponents and Greek letters are one tap away, and the whole keyboard hides when you want the full screen for the graph. PRIVACY SnackLab collects nothing. No account, no sign-in, no analytics. Everything you type stays on your device. Available in English, Korean, Japanese, Chinese, Spanish, Portuguese, German, French, Indonesian and Vietnamese.
