If ever there were an app designed specifically for Alfie, it would be this one. He has had Professor Astro Cat’s Frontiers of Space by Dominic Walliman and Ben Newman (Flying Eye Books, RRP Â£15.99) for some time and reads it regularly, so he was familiar with the prof. He knows a lot about space already, so he rattled through the quizzes and educational games, relishing winning enough stars from each Jetpack challenge to get a medal. You also collect pieces of rocket as you complete tasks, so you can build your own at the end for a satisfying pay off. As in the book, the graphics are retro cool and its jam-packed with galactic facts – I learned loads playing with Alf. Perfect for any mini Tim Peake fans, Â£2.29, the App Store.
