Welcome to Lost on Infinity – Story 3 – the penultimate installment in this award-winning audiobook story for children and adults!

NOTE: YOU CAN DOWNLOAD PART 1 OF THIS AWARD WINNING MUSICAL STORY FREE in the App Store (over an hour of story, music, animation and pictures). PARTS TWO and FOUR ARE ALSO AVAILABLE making up the whole story.

But, if you’re here to download Part 3 of Lost on Infinity (previously known as Rockford’s Rock Opera), you’ll already know about this unique, ecological musical story so... welcome back!

If you're enjoying the story, please do post a review, tell your friends, and join us on Facebook. You can visit our website too; where you’ll find loads more free stuff including free educational materials. We love to hear from you, so please do say ‘hi!’.

As before, due to the rich audiovisual content in our story, Lost on Infinity Part 3 is QUITE A BIG FILE SO PLEASE USE WIFI when you’re downloading. Although we originally made the story for ages 5+, many younger children and young-at-heart adults love the story, animation and illustrations.

That’s it I think? We hope you enjoy the third part of what the Guardian newspaper's App Reviewer recently called;

“The best iPhone prog-rock educational eco-musical App!”

And, if you're still not sure, please take a look at the reviews for our Parts 1 and 2 Apps (many thanks to all of you who've posted – we REALLY appreciate it).

Great chapter book story for kids

My daughter loves this app. I like the way it is organised into chapters so you know exactly how long she is spending listening to it. The app comes in 4 parts so make sure you watch in the correct order.

Excellently produced, wonderful story

A personal note to say thank you to the team that put this together. You work has been truly appreciated by our two children aged 6 and 9. The story is pitched perfectly for your target audience. Releasing the this first part for free enables parents like ourselves to try and see how wonderful your product is. The remaining three parts are priced so reasonably, it's impossible to refuse. Clearly your confidence in your marketing is justified. We look forward to more stories like this one, like so many others, we will be waiting in anticipation.

Well done, products like yours do make the iPad a magical experience.
