Pocket Code
What Pocket Code is
Pocket Code is a free mobile app for making programs, games, animations, and stories by connecting visual programming bricks. Catrobat describes it as suitable for children and teenagers with no programming background, as well as more experienced programmers. Its blocks cover if-else statements, loops, variables, mathematical functions, and phone sensor access. Users can explore, download, review, and remix community programs in the app’s Explore section and on pocketcode.org. Hardware extensions connect projects to Arduino, LEGO Mindstorms, Phiro robots, and Raspberry Pi: the Arduino extension works over Bluetooth with digital and PWM pin changes and analog readings; Mindstorms robots connect to a device over Bluetooth; and Raspberry Pi bricks read and set pins for IoT programs. Catrobat presents Pocket Code as a constructive learning tool for classroom use and provides a wiki and a free MOOC in English and German. The app is available for Android and iOS, and its programming language is Catrobat. The project is free and open source, driven by the International Catrobat Association and Graz University of Technology’s Institute of Software Technology. Project hosting is no longer available as a service, though the media library remains accessible through the wiki. Catrobat is based in Graz, Austria.
