Wattpad

Wattpad is an ebook reader for Android that gives users access to a library of thousands of readily available titles.

Despite making a few questionable design choices for its user interface, Wattpad more than makes up for this with its huge selection of titles, all of which can be downloaded directly to a user's phone for easy reading. Aside from its library, Wattpad also provides support for customization, allowing readers to fully design their own reading experience. This includes support for features like auto-scrolling, as well as library organization functionalities. Of course, it's worth noting that Wattpad requires a user to be connected to the Internet in order for it to remain functional, but aside from that it's a great app for habitual readers.
