If you have used MIT App Inventor (and of course you have!), you can quickly adapt to using Blockly for programming. Blockly is basically a “Drag and Drop” code editor (like in App Inventor), providing a visual programming system. It uses the same ideas as MIT App Inventor.
To see it in operation, visit MIT’s Scratch project to create a simple program.
