Hi guys, I spent the weekend (two weeks ago) coding up an iPhone (iOS5 or later only) app that grabs the 7Timer data and formats it into a simple set of graphs that I think are easy to understand. It's finally been approved for the iTunes store.
It's free and is called Sky Harbinger

Hope it does the job for you and if there are any features people would like to add then just ask and I'll see what I can do.
Cheers,
Simon
