AppInventor.org: Democratizing App Building

Learn to build Android apps in hours.

MIT App Inventor is the fastest way to build apps for Android phones and tablets. Even with no prior experience, you can learn to build apps within hours. You'll learn from USF Professor David Wolber, who has been teaching beginners programming with App Inventor since its inception in 2009. With step-by-step video screencasts, Wolber starts with the basics then leads you through the development of successively more complex apps, teaching you programming concepts as you go.

App Inventor now has a Gallery!

May 19, 2015

App Inventor programmers have been working side-by-side in the cloud together, but they might as well have been using stand-alone software as they couldn’t share their experience. I’m pleased to announce that the App Inventor app gallery is officially launched as part of MIT App Inventor. Students and developers can now easily share their apps and code blocks and learn from each other. The gallery turns App Inventor into a shared learning community similar to the one which has been so successful in Scratch. Now all the students, teachers, and developers who were blindly rubbing virtual shoulders can share their apps in a great, collaborative open-source environment.

The gallery was developed by our team in the Democratize Computing Lab (DCL) at the University of San Francisco (the same team that brings you appinventor.org and this blog), working in collaboration with the MIT App Inventor team. Special thanks go to lead developers Bin Lu and Vincent Zhang of USF, as well as mastermind Jeff Schiller of MIT, all of whom put in a long and concerted effort in making the gallery a reality.

The Democratize Computing Lab is generously funded by the W.M. Keck Foundation.
