Leatherbound is a new, free universal application that allows users to compare e-book prices across the iBookstore, Kindle Store and NOOK Book Store.

The application looks great and works well. Features include e-book searching, plot summaries and the ability to share information viewed within the application via email. Furthermore, there’s that all-important price comparison feature, which tells users of the app exactly where the cheapest place to buy an e-book is.

You can purchase your desired e-book from within the application, or search for more via author, title or category. As mentioned, Leatherbound is a universal app – meaning it’ll run natively on the iPhone, iPad and iPod touch.

If you’re an avid e-book reader, be sure to take a look at Leatherbound. It’s currently available to download for free in the App Store.
