The last week and a half we (the AppyBuilder team and myself) worked really hard to convert the App Inventor beginner tutorials to AppyBuilder.
The tutorials can be downloaded with the following link:
The originals can be found here: http://appinventor.mit.edu/explore/beginner-tutorials-short.html
The AppyBuilder tutorials will be released with the same license https://creativecommons.org/licenses/by-sa/3.0/
Any comment would be appreciated.
