SupplySide West
The West edition was the only one to have an app developed but is in its second year, having debuted the idea in 2011.
Developed by Virgo, the app gives the usual organizational options, as well as a link to use Twitter whilst at the show, and see what is trending.
It also includes a bio section for each speaker at the event, which took place last week. The app should return for its third outing next year.
