Apps are a new concept that have been floating around Drupal for the the last year or two. And while they are just modules, often the question is why should I make an app instead of just using a module. This session explores reason to make a app, and when it might be better to work on the interface for the module instead of building an app on top of it. I will then do a quick example of how to build an app, and talk about building an app eco-system.
