Ladybird Me Books App for iPad, iPhone and iPod Touch
The app costs 69p and once downloaded gives you access to one title - The Zoo. It's a simple enough idea; tap various spots on the page to hear the text read aloud and the sound effects - in this case the various animals at the zoo. The added twist is that you can also record yourself (or your child) reading the story - and even make your own noises if the fancy takes you.
There are a further 10 titles available, costing £1.99 each. Find out more at the App Store.
