The Kindle app on iOS has just had an update to version 4.1, which brings with it several new features. For students, there are flashcards and in-book search; for readers, there are notebook filters, how much of the book is left, and more. Amazon has also made the app more stable and improved performance.
Using X-Ray, students can now convert important terms from textbooks and notes into flashcards, improving their recall of the subject. The X-Ray feature itself has got an update too, allowing readers to sort characters and terms by relevance, alphabetically, or in order of appearance in the book.
It seems that Amazon has also bettered its OCR (Optical Character Recognition) capabilities as search in print replica textbooks is faster and more powerful, complete with instant auto-complete suggestions as you type.
Notebook filters let readers refine bookmarks, notes and highlights, with the ability to directly navigate to the annotated passage. Such annotation tools might be all that’s needed to decide the winner in the war of Kindle vs. iBooks.
Meanwhile, page footers show you how much of a book you have left and how much is left to read, by showing the page number or time left in a book. You can also switch this off for a blank page footer.
Other improvements to Kindle for iOS 4.1 include a redesign of the dictionary and multi-edit capability in the library view. You can download the new Kindle from the iTunes App Store. And once you get it, Bakari has a great guide on setting up Kindle on your iOS device.
