Today we’re shutting down MIT App Inventor Classic. It’s been a great run. Even here at the end, the system is hosting 3000 active users a week. That’s down from 6500 in May, and vastly down from the peak of 30,000 active users a week in January 2014, when we first began encouraging people to move to App Inventor 2.
App Inventor Classic was adapted from the original Google App Inventor system, whose implementation began in 2009. The Google App Inventor team: Mark Friedman, Sharon Perl, Liz Looney, Ellen Spertus, Debby Wallach, and Karen Parker spent six months refactoring the code so it could be open-sourced. MIT then took over development and spent more months preparing the MIT App Inventor service, which we launched in spring 2012.
MIT App Inventor Classic has performed admirably as a transition from the Java application-based Google App Inventor implementation of 2010, to the browser-based MIT App Inventor 2 system of 2014. Over its three and a half year lifespan, Classic has welcomed 1.7 million users, who among them created 3.97 million apps.
Let’s raise glass (or a phone!) in salute and carry on with App Inventor 2.
