We are combine all the beginner apps together, with each app on a different screen. There are several reasons for this that will become clear later, but it means creating a "master" app with a menu and an About screen before we even get started on the beginner tutorials.

Navigating between screens is key; let's start with the About screen. Adding new screens is simple enough - we will name them according to their purpose. There is no renaming of Screen1, and the app always starts there - it's why we is it for our main menu.

Right now, the screens we added are essentially dead ends. Every screen will need button in the upper left-hand corner returning users to the main menu by closing the current screen. We also want users to exit the app gracefully, so add a button on Screen1 that does that.

Our About screen lets users know about the person who made the app. We'll copy and paste our text from our About Me section of our portfolio, because App Inventor is NOT the place to try and write more than a few words. Make the font large (between 40 and  60, more or less) that the scrolling feature of the vertical arrangement we're using is needed to read the whole thing.

Now we create a version of "Hello Codi" on the HelloCodi screen. Each tutorial has a DATA PDF version. The image and sound files can be downloaded directly from the PDF instructions - upload them to the Media panel so they can be referenced in the Properties panel when needed. Follow the instructions in the Media section above.
