Kitabu is a handy Mac application that allows you to read any e-books (electronic books) that you might have stored on your system in ePub format.
Not only that the lightweight Kitabu lets you read e-books in a very easy way, but it can also provide you with a library where you can store your entire e-book collection so that you won't have to load them every time you wish to read a specific book. You can do that with just a simple click of a mouse.
Kitabu puts at your disposal several modes in which you can read your e-books. You can view the contents of your book in one or multiple columns, display the table of contents so that you can easily jump to any desired chapter or you can even modify the size and font of the text, as well as the background color in a matter of seconds.
Other than that, Kitabu comes with a simple and clean interface and the only thing you can modify is to select what action to perform when importing the e-books into the library (move or copy them).
To sum it all up, if you are looking for an easy-to-use Mac application that allows you to read e-books in ePub format, then the lightweight Kitabu is a good choice.
