Geometry Pad+ vs GeoGebra Geometry

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. We'd love to hear from you: tap Share feedback in the app's Help menu.
