As part of the course "Cognitive Sciences and Technologies", held by Professor Antonio Rizzo, I created the site linked below for the purpose of collecting applications produced following the online course "Course in a box", designed to introduce the basic concepts of programming through AppInventor .
AppInventor is a development environment designed to facilitate the creation of Android applications by representing parts of the code as pieces of a puzzle to be mounted. The tool allows you to test the code in real time, connecting your mobile phone and computer using the AICompanion application.
For each application contained in  "Course in a box" I created an updated version, justifying the changes both in terms of usability and additional functionalities.
