In this part of my App Inventor tutorial, I will provide an App Inventor TinyWebDB Example. This one should be fun. We’ll be making a chat application that I call IncognitoEx. It will allow you to chat with anyone who also has the app. I have the APK on my site if you want to try it out.

It allows you to send and receive messages. You can even make your own TinyWebDB web service.
