There's An App For Led Zeppelin

"I had the idea of making individual apps for some of the biggest acts in the world, and thought the best one to start with would be Zeppelin, because of their iconic status," said Neil Cossar, of This Day in Music, in a statement about the app.

Among the app's features: a detailed list of every show Led Zeppelin every played, a Zeppelin quiz with hundreds of questions, critiques of every track the band ever recorded, a career overview of the group, photographs of the band and more.
