Previously known as Rockford's Rock Opera, just some of the hundreds of reviews for Lost on Infinity.

"An amazing mix of story, songs, and sound effects!" THE TIMES
“A stunning creation.” B B C RADIO
“An ingenious story.” THE GUARDIAN

Welcome to Lost on Infinity® – STORY 2. Formally known as Rockford's Rock Opera, this is the second amazing installment of the world’s most popular enhanced audiobook, and now the planet’s most popular kid’s audiobook App.

NOTE. PART ONE of LOST ON INFINITY is AVAILABLE FREE from the App Store (includes over an hour of animation, pictures, story and music.) PARTS THREE and FOUR are also available making up the whole amazing two and half hour adventure.

Winner of the prestigious iParenting Media Award, in this App there are over 40 minutes of story, songs, music, pictures and videos, continuing the story of Moog, Rockford and the Cocklebur Ick and their extraordinary adventures on the Island of Infinity.

A hit across the world – take a look at our reviews – if you haven’t heard Part One of the story yet, go to the App store now and download it FREE!

This App is SUITABLE FOR ALL AGES (we really RECOMMENDED it for 5 – 12 YEAR OLDS – and their families – but it seems from our reviews, far younger children love the story and visuals).

Created by Elaine and Matthew Sweetapple and written by comedian, Steve Punt, Rockford's Rock Opera is supported by the World Wildlife Fund (WWF).

Great story about Rockford

The registrar should be arrested. I like Rockford, the thing I must know why the registrar is trying to make everyone become extinct. Why do the animals not like humans.
