Leio is a digital journal to help you track and manage your reading. It's designed primarily around physical books, but you can also use electronic readers or other devices. Leio helps you organize your library, your notes and your favorite quotes, but that's just the beginning. Timing your reading sessions makes it easier to set aside some time and turn reading into a habit. The data gathered this way quickly turn into an extensive record of your reading life, providing you with statistics and information about your habits. These data can also be projected into the future: Leio will tell you when you will finish each book and help you plan accordingly.
