MegaReader (iPhone, iPad and iPod touch)
MegaReader is one of the most robust and useful eReader apps I've come across. There's certainly no shortage of similar apps for iOS, Android and the other mobile platforms. But MegaReader is different because its interface is completely customizable. It makes finding interesting books from recognizable authors simple; you just navigate the alphabetical catalogue of books, which is composed of more than 1.8 million free options, and download the ones you want. MegaReader offers access to tons of classic novels, but you'll also find new works from indie publishers and authors.
