App Inventor — a Google cast-out that is now maintained by MIT — is a graphical tool that unlocks the power of an Android handset to those with the most basic of programming understanding.

MIT’s project is part of the Center for Mobile Learning, which announced several months ago that it would be taking over App Inventor when Google shut down the service on December 31, 2011.

And because applications can now be created in-house without even relying on any external libraries, those applications made by App Inventor will be free from hidden vulnerabilities or malicious code.
