Is this meant more as a historical episode guide, or a current episode/TV Guide type of application?
The reason I ask , is I was looking for just such an app last week (The current and upcoming episode type), and found one that works rather well and seems well polished already..
It's called "TV Show Favs" and has the ability to flag shows for your own listing, see upcoming schedules by day, get episode synopsis, guest stars, and you can even look up any show, and look at it's historical episode info.
Not that having another app isn't fine... but you might want to see if you can differenciate your app vs this one in some fashion.. your screens look very nice already, but as a user I'd ask myself "What can this new app do that my current one cannot'.
Good luck on the development though...
