Sending Notifications And Using Variables on MIT App Inventor 2

What is MIT App Inventor 2 ?

You build apps by working with:

• The App Inventor Designer, where you select the components for your app.

• The App Inventor Blocks Editor, where you assemble program blocks that specify how the components should behave. You assemble programs visually, fitting pieces together like pieces of a puzzle.

Your app appears on the phone step-by-step as you add pieces to it, so you can test your work as you build. When you're done, you can package your app and produce a stand-alone application to install.
