Plott: Graphing Calculator

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 —

• 100% offline — no account, no tracking, no data collection

• 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.
