The downloadable app (for Mac/Windows) does require iTunes. The web version doesn't.
The advantage of the downloadablee app is that the qrcode reader is *really* fast. The flash qrcode reader on the web does an adequate job but isn't nearly as fast or as satisfying to use. We developed the web version for people who wanted to try it out withoug having to download an app or use iTunes.
iCandy is an outgrowth of multimedia research and tangible user interfaces. We use iTunes because it is a repository of multimedia and writing an application for iTunes was much more focused and straightforward.
Someday we might write a version of iCandy that doesn't require iTunes.
