Geometry for iPhone

Overview

Geometry is a free iPhone app created by Zbigniew Osada that helps with geometric computations. It’s intended as a practical aid for anyone who needs quick, reliable math related to shapes — from high-school students to instructors and hobbyists.

Capabilities and Examples

• Compute volumes for solids such as spheres and cylinders.
• Find perimeters of planar figures, for example rectangles.
• Calculate areas of common shapes like triangles and circles.
• Determine totals such as the sum of edges for polyhedra.

The app supplies standard formulas alongside clear diagrams so you can follow the steps visually. Enter the dimensions, and the tool returns precise results.

Design and Workflow

• Clean, straightforward screens keep input simple and fast.
• Intuitive controls let users enter measurements without a steep learning curve.
• Immediate calculation feedback reduces the time spent on manual work.

These design choices make the app approachable for users with various levels of math familiarity.

Who Benefits Most

• Secondary- and post-secondary students studying geometry.
• Teachers needing a quick reference or demonstration aid.
• Anyone exploring geometric problems or doing basic engineering/design checks.

Alternative to Consider

Simply Learn Mongolian — Mongolia Travel Phrases (free) is listed as a recommended alternative in the app store; it’s a language/phrasebook app rather than a math utility, so consider it only if you’re looking for travel or language learning tools.

Bottom Line

Geometry is a compact, user-friendly utility that streamlines standard geometry calculations. With its diagram-backed formulas and easy input flow, it’s a handy addition to an iPhone for both learning and quick reference.
