About

sketchometry

This app transforms your finger drawings into precise geometric shapes on your iPhone or iPad. It turns math into an experimental subject, encouraging learners to discover concepts through hands-on interaction rather than presenting pre-made solutions.

Highlights
  • Finger-to-geometry conversion
  • Dynamic mathematical exploration
  • Experimental learning approach
  • Interactive geometric drawing
  • Supports iPhone and iPad

Fascinatingly simple. Simply fascinating. sketchometry is a different kind of dynamic math software. You draw with your finger on your iPhone or iPad. sketchometry automatically converts these (finger) sketches into exact geometric objects. Mathematics becomes an experimental subject. No ready-made results are presented, learners are encouraged to go on a journey of discovery by themselves.

About

Dynamic Geometry Sketch Pad

This app is a dynamic geometry and mathematical computation tool. It allows users to create geometric figures, input complex mathematical formulas, and perform various measurements and transformations. All visual elements are displayed in an infinite scrollable area and can be permanently saved.

Highlights
  • Dynamic geometric constructions
  • Natural mathematical formula input
  • 25 built-in mathematical functions
  • Infinite scrollable drawing area
  • Permanent file saving
  • Undo/Redo editing
  • Geometric transformations

Sketchpad is a set of mathematics dynamic geometry, mathematical computation, formulas input application. Using mathematical drawing board, you can replace the Ruler mapping, but you can make advanced image and function of the image trajectory, can dynamically change their properties, measure their relative value, you can create custom variables, custom functions, using natural mathematical formula input expression, beautiful, clear, inside it is built up to 25 common mathematical functions. All visual elements are displayed in a scrollable Sketchpad infinite area, Sketchpad area content can be permanently saved as a separate file. This program includes the following features: Formula features: - Sketchpad provides fractional, radical, radical times, index, subscript, A superscripts arranged formula, C and superscripts combination formula, Σ summation formula, Π quadrature formula also provides Greece enter letters, overline formula (expressed segments), the arc formula (expressed arc) and other mathematical formula, the formula can be pre-cut, copy, paste, natural way to enter, the natural way to edit, and consistent operation iOS text edit.
