iBooks is an e-book reader and storefront that lets you purchase or download free books and textbooks you can read on your iOS devices. The latest version of the software adds an unlimited scrolling feature, new iCloud support for syncing up your libraries, free automatic updates for your books, and more.
Like other e-book readers, iBooks responds to the device's accelerometer and switches between landscape and portrait modes. Its controls disappear when unused, and a swipe (or tap on the left or right side of the screen) will cause the pages to turn. iBooks' page-turning has a smooth animation showing page corners digitally curling toward you as you advance. You also have the option to switch from book theme (with page-turning animations) to full-screen or scroll themes. The scroll theme is new in iBooks 3, letting you swipe up or down for a continuous reading experience. You can choose from six fonts to give your books a different feel and three page colors to suit your reading style. iBooks also includes a progress bar to show how far along you are in a book, and you're able to change the font size to make reading easier.
