If you’re like us, you’ve reached the point where you actually use the “Search iPad” feature because you’ve lost the ability to scroll through pages of apps to find the one you’re looking for.  If you’ve finally decided to download only apps you’ll use (no more Cut The Rope) here’s where to start.  It’s called This Day in Led Zeppelin and if you’re a Zeppelin fan, it’s first page app worthy.  From the guys who run the award winning This Day in Music site, This Day in Led Zeppelin is loaded with Led Zeppelin knowledge.  Download it and get a list of every gig the band ever played with set lists, an interactive directory of important Led Zeppelin events for each day of the year, and quizzes to test your Page and Plant brainpower.  It’s way better than waiting for your local rock station to get the Led out weekdays at 5.
