The Amazon Kindle iOS app has been updated to version 3.5, introducing the long-awaited new X-Ray feature.
The app, available for free from the Apple App Store, now incorporates X-Ray for Books, which has been available on some Kindle devices for a while. X-Ray enables users to highlight a character, phrase or place in the book that they’re reading and receive detailed information on it, supplied by Wikipedia and Shelfari.com (Amazon’s own community-powered encyclopaedia).
It’s a feature which can come in handy when reading novels with a large number of characters (Amazon’s images of the app use George R. R. Martin’s A Song of Ice and Fire as an example) or locations, or to become more clued-in on real-life historical figures in books.
At present, X-Ray only works with selected books, all of which are in English. If a title is popular, it’s highly likely to support X-Ray; there are also some textbooks compatible with the feature.
The new Amazon Kindle iOS app is available now for iPhone, iPad and iPod touch devices, although you’ll have to be running at least iOS 5 to use it. As well as X-Ray, it also adds improved support for Manga images.
