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.
