Now that I've look at this app - sorry mate, but it's just terrible. Lets start with the first magazine I bought (and paid $5.29 for), NZ Performance Car - a mag I probably would buy, at least on a semi-regular basis if there's something that looks good on the cover.
Here's the first few pages, after I briefly get the cover flashing up, then it changes to this page by itself.

Uhhh....OK, real good look.

OK, that page is half in focus I guess. An improvement!

Spoke too soon.

Oh hey here's the cover again! What's that other page though?

What the christ?

And here we go, content finally. What happens when I zoom in so I can actually read it?

Oh. Totally unreadable.
You're simply doing a straight digital render of the magazine layouts straight out of pre-press or whatever, and this is a prime example of doing it all wrong and actually totally ignoring what the iPad platform offers you. If you want to see how it SHOULD be done, what you should be aiming for, look at mags like National Geographic, possibly the highest quality magazine app on the platform. Don't settle for mediocrity.
But the most important thing you're doing wrong? YOU'RE NOT USING NEWSSTAND. This dooms you to total failure. Fanboys aren't going to use you because it's an awful app and you're not using the Newsstand platform, and normal people aren't going to use you because you're not in Newsstand so they don't care and aren't going to see you.
As it stands, the $5.29 I just spent on this NZPC magazine is a total waste of money because it's purely unreadable. This is a terrible app and you should feel terrible for having anything to do with it.
