Below are some different tutorials for you to follow, depending on the type of app you are building.
ACTIVITY: TRY A TUTORIAL
Don't just watch the tutorial - make the app too!
If you don’t see a tutorial below that has some of the same features you want to add to your app, there are many other ways to find help!
- Google “App Inventor” and whatever feature you want. For example, you might Google “App Inventor quiz” if you wanted to make an app that tests users on a topic.
- Visit http://appinventor.mit.edu/tutorials and look for other tutorials that might be helpful.
- Visit https://community.appinventor.mit.edu, the community forum for App Inventor users, and post a question there. Many other App Inventors visit that site and assist others that need help.

GREEN TRACKER APP
In these tutorials, learn how to use TinyDB to create an app where users can track their green activities from day to day. Their tracked information is stored on the mobile device so it can be updated each day.
Green Tracker tutorials
In this advanced tutorial, you can add to the Green Tracker by using a Clock component to see whether the user has done green activities one day after another, and you can reward them for their commitment to being green.
This tutorial gives you some tips for how you can change values in your app to help with testing. In this case, you are “tricking” your app by saving which day you last did something green, so you can test the new day tracking feature from above!
