With the birth of the Duke and Duchess of Cambridge's first child imminent, British magazine Future is hoping to capitalise with a commemorative app for iPhone and iPad. Royal Baby App: Kate and William's Birth Celebration was released on the App Store, as speculation increased about the due date for the birth. The app is a free download, but sells individual sections – Royal Baby Special 1, Royal Babies, Meet Dad, and Will & Kate – as 69p in-app purchases, taking advantage of an increasingly-popular business model on iOS.
