App Inventor is a free, cloud-based service that allows you to make your own mobile apps using a blocks based programming language. You access App Inventor using a web browser (Chrome, Firefox, Safari). With these beginner-friendly tutorials, you will learn the basics of programming apps for Android devices.

You will need:

You will make a mobile app, so it's fun to see it run on a phone or tablet while you build the app (and after!). Some setup required to run your apps.

Choose which way you want to connect to run your apps, and follow the links to setup instructions:

  • Android mobile device (phone or tablet) and wi-fi

    Making Mobile Apps with App Inventor


    We have four beginner tutorials to try out. We recommend starting with Hello Codi!, but any of the four tutorials are accessible for novice coders. They can all be completed within an hour timeframe.

    For each tutorial, we have multiple ways of accessing them:

    • Click the tutorial link to open up a project directly in the App Inventor environment with the tutorial in the sidebar. This is our recommended way to complete the tutorials. Note that each of these can also be used for Hour of Code events.
    • If you prefer, you can click on the video links to follow the tutorial in a video. Please note, this requires you have two windows open in the browser - one to play the video, and one to run App Inventor.
    • We also have links to pdf files for each tutorial, for those of you who prefer following text instructions.

    After building the starter apps, which will take around an hour, you can move on to extending them with more functionality, or you can start building apps of your own design.
