sketchometry is a dynamic geometry software designed to make planar geometry more accessible and interactive. With this app, users can easily sketch desired objects using their fingers or a stylus and create geometric constructions. The software recognizes the drawn object and generates an exact image, making it easier to explore mathematical concepts.

One of the most impressive features of sketchometry is the ability to manipulate geometric objects. Users can take the objects "in hand" and rotate or change them as they please. This makes it easier to understand mathematical relationships and explore different possibilities. The app also allows users to save their designs locally or in the cloud, and export them as HTML pages or interactive e-books.

Developed by the Department of Mathematics and Didactics at the University of Bayreuth, sketchometry is free to use. It is a great tool for math enthusiasts and students who want to explore geometric concepts in a hands-on and interactive way.
