MIT App Inventor Overview
MIT App Inventor is a free, web-based tool from the Massachusetts Institute of Technology that lets people build real Android apps using a visual, block-based programming approach instead of writing code. It is designed to make app creation accessible to beginners, students, and educators: you design an app's screens by dragging components like buttons, labels, sensors, and maps onto a layout, then define how the app behaves by snapping together colorful logic blocks. Because it runs in the browser, there is little to set up, and a companion app lets you test your creation live on a phone or tablet as you build, or in an on-screen emulator. App Inventor can access device features such as the camera, location, and sensors, and it has been used by millions of learners worldwide to create everything from simple quizzes to community apps. Finished apps can be packaged for installation on Android devices. This page links to the official MIT App Inventor source.
