PaintPot lets you scribble in different colors by touching the screen to draw dots and lines. Concepts introduced in this project include: Canvas components for drawing; event handlers that take arguments, including touch and drag events; and Arrangement components for controlling screen layout. Part 2 extends the project to draw dots of different sizes, as an introduction to global variables. Variation: PaintPic extends this app to use the camera component to take a new picture for drawing upon. This version of the tutorial is for use with App Inventor 2.

Pizza Party is a database app that collects dinner orders from different people and stores them in a Google Fusion Table. The app also uses the WebViewer component to let the user see the entries in the table. Fusion Tables are Google's free cloud database solution. Your fusion table can be read-only to the public, or you can grant multiple people the permission to write to the table. See the tutorial for more information, and begin creating your own shared database solutions!

QuizMe is a trivia game about baseball, but you can use it as a template to build quizzes on any topic. With QuizMe the user steps through a series of questions, clicking a Next button to proceed to the next question. The user enters an answer for each question and the app reports whether each answer is correct or not. For this tutorial, you'll create an app in which the questions are always the same unless you, the programmer, change them. Later, you can create MakeAQuiz, an app that lets users create and modify the quiz questions.
