In the coding community, “Hello World” is the first program learned by a novice coder. Similarly, I created my first project, “Hello Purr,” and named the project Hello Kitty Purr. This week was my first-week creating an app using App Inventor. I learned how to use an image as a button, create labels, and apply a background color. I chose to use a Hello Kitty image, rather than a traditional cat. Also, I learned how to use some of the behaviors that the user will interact with. When the user presses the button or shakes the phone, the Hello Kitty will purr, and the phone will vibrate. To conclude the lesson, I learned how to publish my app by creating a QR code. This app is a simple app that does not have many teaching functions but was a great introduction to App Inventor.
