Geometry Pad+

Geometry Pad+ turns your iPad into an infinite canvas for exact plane geometry. Build points, lines, triangles, polygons, circles and conics with a few taps, and they stay exact: a square stays a square, a parallel stays parallel, and an intersection point stays on its crossing however you move things around.

Every feature is included. No subscriptions, no in-app purchases.

CONSTRUCTIONS THAT STAY CONNECTED
• Parallel and perpendicular lines, perpendicular bisectors, tangents, chords and intersection points follow their shapes as you drag them.
• Altitudes, medians and angle bisectors of triangles and polygons update as the shape changes.
• Right, isosceles and equilateral triangles, squares, rectangles, parallelograms, rhombi and regular polygons keep their kind when you edit them.

PRECISION BY TOUCH
• Points snap to the grid, to vertices, midpoints, sides and curves, and to the crossings of shapes.
• A magnifying glass shows exactly where each point lands.
• Type exact coordinates, lengths, radii and angles with the built-in calculator.

LIVE MEASUREMENTS
• Every shape shows its lengths, angles, slopes, equations, perimeter and area.
• Place measurement labels on the canvas. They update as you move the shape.
• Show the angles where lines cross with a single tap.

CLASSIC INSTRUMENTS AND TRANSFORMATIONS
• A compass that draws arcs, and a protractor that draws segments at an exact angle.
• Rotate, reflect and translate shapes, or copies of them.

SHAPES FROM NUMBERS
• Build lines from their equations, triangles from their sides and angles, quadrangles from their sides and an angle, and parabolas and hyperbolas from their equations, with a live preview as you type.

WORKSHEETS AND DOCUMENTS
• Import a PDF and draw and measure on top of its pages.
• Create documents with several pages, on an infinite canvas or on A4 and A3 paper.
• Add pictures from the camera or photo library, and notes in text boxes.
• Export as an image (with cropping), PDF or SVG, or share the document itself.
• Your work saves automatically to the Files app. Documents from the previous Geometry Pad open too.

MADE FOR THE CLASSROOM
• Cartesian, polar and isometric grids.
• Real centimeters and inches on screen.
• Seven themes, including chalkboard and blueprint, and full dark mode support.
• Apple Pencil, keyboard shortcuts, multitasking and VoiceOver.

Geometry Pad+ is for teachers preparing lessons and worksheets, and for students exploring geometry on their own.
