Easy Geometry

Enter what you know about any shape and Easy Geometry solves the rest instantly. Circle and Ellipse are free to try — unlock every other shape with one purchase.

Easy Geometry is a fast, focused calculator for every shape you'll ever need to solve — 2D and 3D, from a simple circle to a right circular cylinder.

Just enter what you already know — a couple of sides, an angle, an area — and Easy Geometry solves for everything else. No hunting for the right formula, no algebra by hand.

WHAT'S INCLUDED

Closed Curves — Circle, Ellipse

Triangles — Oblique, Scalene, Isosceles, Equilateral, Right

HOW IT WORKS

Every shape has its own calculator: type in a combination of known values, and Easy Geometry finds a matching formula and solves for the rest — area, perimeter, volume, diagonals, angles, whatever the shape supports. Each shape also includes a labeled diagram and a plain-language explanation of its properties and formulas, so it works as well for a quick homework check as it does for the day you actually want to understand why a formula works.

Built for iPad, with a clean, distraction-free interface and a numeric keypad designed specifically for fast decimal entry.
