For one of my last projects with Sigi Torinus as part of my BFA degree I made an iphone App.
I was able to speed up a usually lengthy process by skipping over the coding portion of creating the app. This was made possible by using Buzztouch, a web-based content management software (CMS) out of Montery California that helps build iPhone and Android apps. Buzztouch provides tools that allow people to create mobile apps and provides a back-end database to support those apps over the long-term. They do both of these things for free, for anyone. The source-code that app owners download for each of their applications is released under an open-source license.
