This Stephen Fry-narrated pp takes you into the exciting world f nature’s extinct giants

Inside The World Of Dinosaurus For iPhone is a giant-sized interactive encyclopaedia of over 60 species of dinosaurs. You get to see all the old favourites, like Tyrannosaurus Rex, Triceratops and Stegosaurus as well as lesser known Therapods, Sauropods and Cerapods of the Triassic, Jurassic and Cretaceous time periods. While there are different ways to access the dinosaurs (by Timeline, Period or searchable index), the main meat of the app is a series of dark, book ­like pages, which use the same landscape layout for every single dinosaur. Sadly, that means things quickly start to become repetitive. There are over 200 pages containing 3D models, enabling you to see the dinosaurs move, run or fight. Essentially, each dinosaur gets two pages dedicated to it ­one giving an overview and an animation showing you how it walks, and another which contains more information alongside a 360-degree spinnable image, and a second image of the dinosaur either running or fighting.

The text on each page is narrated by Stephen Fry, who is more than up to the task of enunciating even the most absurdly long Latin or Greek-inspired dinosaur name. As expected, Fry does a great job at making the unpronounceable sound positively palatable.

The videos aren’t great and the static pictures just don’t really add anything of value either.

To be fair, M5859 Studios seem to have made an extra effort to get the science right – it claims over 30 specialists in their fields collaborated for 12 months . There’s certainly an impressive amount of historical information about paleontology here, with articles and biographies of famous fossil hunters. Even so, while the text is packed with interesting facts, it’s not stuffy. In fact, it’s positively accessible and contemporary.

Of course, we can’t finish this review without mentioning the elephant (or in this case, the Brachiosaurus?) in the room – its price. £9.99 is small fortune!
