Project Summary
Catrobat is a mobile visual programming system. Catroid and Catty are IDEs and Catrobat interpreters for Android and iOS. Paintroid is an associated paint program for Android that, among others, allows setting parts of images to transparent. There are many subprojects, e.g., allowing to control Arduino and Raspberry Pi boards, or to program Lego Mindstorms robots or an embroidery machine. We use Test-Driven Development along with other agile methods such as Kanban, ensuring a clear and 100% up-to-date documentation.
