MyBookManager is a reading management app that helps you record and organize your reading life. Register and manage your books Search for books you want to read through Google Books and add them right away. If you can’t find a book through search, you can also register it manually by entering details such as the title, author, and page count. Registered books can be organized into four statuses: Reading, Want to Read, Finished, and Paused, so you can easily see your current reading progress at a glance. You can also manage paper books and e-books separately, and leave notes, reviews, and ratings to build your own personal reading journal. Record your daily reading If you read a book today, leave a daily reading record. With the calendar, you can check which days you read and which books you finished at a glance. When you enter the current page of a book you’re reading, the progress rate is calculated automatically, so you can instantly see how much is left until completion. Start dates and finish dates are also recorded, allowing you to look back on how much time you spent reading each book. Look back with reading reports Check your monthly and yearly reading statistics through reports. See how many books you read this month, how your reading compares to last month, and how many books you have finished this year. As you keep recording consistently, your own reading patterns will gradually become visible. Group books with collections Create collections by genre, topic, or your own personal standards. Organize your books freely, such as “Novels I Read This Year,” “Recommended Books for Developers,” or “Books I Want to Read Again.” Manage your spending with receipts Register the prices of books you purchased as receipts and manage your book spending history in one place.
