Note: I listen to Talk Show only occasionally, I'm more of Hypercritical guy.
So, Dan wanted an iOS app for some time now (year? more?) - and he was working with Black Pixel (http://blackpixel.com) on that.
We don't know exactly why, but that app was never released - Dan stopped talking about it (I'm not actually sure about this, somebody please correct me if I'm wrong.). Recently, he (again, not sure) wrote new app - that's what's on App Store as 5by5 app.
Parts of "old" app were apparently reused by Black Pixel while working on Mule Radio app (also by Black Pixel.).
