Pocket Code allows you to create, edit, execute, share, and remix Catrobat programs in a visual, "LEGO-style" programming environment. You can develop your own games, animations, interactive art, e.g., interactive music videos, and many kind of other apps, directly on your phone or tablet. You can remix programs that others have made and share them with your friends and the world. With Pocket Code you can up- and download Catrobat programs through the Pocket Code community website at https://pocketcode.org/ --- All Catrobat programs uploaded to this site can be downloaded by anyone under a free open source license to maximize learning, remixing, and sharing them freely.
Catrobat is an independent non-profit project creating free open source software (FOSS) under AGPL and CC-BY-SA licenses. The growing international Catrobat team is entirely composed of volunteers.
