If you press the Bookshelf button you will see a list of all the books currently installed on your phone. To navigate through your library of books simply flip your finger up and down the screen. When you have found a book you are interested in reading, press the books title or cover and the book will open to the title page.

Aldiko makes navigating through a book simple and enjoyable. The background colors are customizable and so is the text and style of use. In the mode viewed above, the book text is displayed vertically and you change pages by swiping your fingers across the page. If you are in low light you can activate the night viewing mode by pressing the menu button on the phone as seen below. The resulting image will provide a higher level of contrast, with white colored text for better low light viewing.

Although Aldiko automatically remembers where you are in the viewing of a book, you also have the option of setting bookmarks for specific pages. To make adjustments to the text size and style, press the Settings button and then Font Settings. The Font Settings selection will allow you to alter the Font Family, Size and Weight. I found these options to be very useful and made the Aldiko Book Reader a capable program for reading text.

Two more options available to help customize Aldiko Book Reader I found useful, was the Layout Settings and Navigation Controls. The Layout settings will allow you to space the text distance from the boarder of the screen and between lines of texts. This will allow you  to place the text on the screen in a manner that is pleasing to your eye. The second option is the Navigation Controls which dictate how you will interact with the text on the screen. You can alter how the pages change, the direction the pages change and what tapping the screen will do. All of these options solidify Aldiko's status on Android as a useful eReader app.
