Ibooks is a well appreciated e-book App originated by Apple Inc. in 2010. It's specifically designed for IOS and OS operating systems and devices. Ibook was initially in conjunction with IPAD, and was released for the IPhone and Ipod touch in mid-2010. But it was not a build-in app and users may download the app from Itune app stores for free.
