PlotterX

PlotterX is a free, graphing calculator for 2D functions and 3D surfaces — no ads, no accounts, no data collection.

2D GRAPHING
• Plot multiple functions at once, each in its own color
• Automatic detection of roots, axis intercepts, and intersections between graphs, with coordinates labeled
• Adjustable grid spacing and clear axis labels
• Pinch to zoom, drag to pan

3D GRAPHING
• Plot surfaces defined as z = f(x, y)
• Rotate and zoom with simple touch gestures
• Shaded, depth-sorted rendering for a real sense of depth
• Multiple surfaces at once, each in its own color

BUILT FOR TYPING MATH
• A dedicated on-screen keyboard for math: sin, cos, tan, cot, inverse and hyperbolic trig, log, ln, square root, absolute value, e, π, and proper exponents — no need to hunt for symbols on a regular keyboard
• 10 ready-made example functions and surfaces to get started instantly
