With a database of more than 12 million titles, Goodreads for Android and iOS is more than a social network for avid bookworms. It's where to go to figure out what's next on your reading list. You can keep collections of titles you want to read, review titles once you're finished and organize your reading history. Find content you might like from reading others' reviews and checking out what your friends are reading. However, the small e-book store contains just 2,000 free books.
