About MIT App Inventor
MIT App Inventor is a free, block-based tool for building mobile apps. It runs in a web browser, so there is nothing to install, and it is used widely in schools and by beginners.
What it does
You build an app by arranging visual blocks in an editor and testing it on your own phone or tablet. The MIT AI2 Companion app for iPhone and Android connects the editor to a device. Tutorials are grouped into beginner, intermediate and advanced levels, and cover topics such as generative AI, maps, the camera, saved data and machine learning. Video tutorials are also available on the project's YouTube channel.
