"■ App Overview ""Where did I leave off in that book?"" ""I thought I had it, but did I sell it?"" A book lifecycle management app is here to resolve all such confusion. Book-Lifecycle-Manager goes beyond simple collection management. From the moment you think ""I want it"" until the time you ""let it go."" It records every aspect of your relationship with your books, allowing you to build your own library right in your pocket. ■ Do you have these concerns? Wondering ""Do I have this book?"" at the bookstore and ultimately regretting not buying it Forgetting how many volumes of a series you've bought and accidentally buying the same volume twice Unfinished books piling up, making it hard to track your reading progress Feeling frustrated because you can't remember the title of a book you sold long ago Tending to forget to return borrowed books Book-Lifecycle-Manager solves all of these problems! ■ 5 Features of This App1. Status management covering a book's ""entire life"" You can meticulously manage books through 5 steps, from before acquisition to after letting them go.Before acquisition: List books you want or plan to read. Acquisition method: Clearly distinguish between books you bought and books you borrowed. Reading status: Unread, reading, finished. You can also record the number of pages progressed. Letting go: Keep a history of not only the books you own, but also those you've sold or lost. Nature: Manage both e-books and physical books together, regardless of the device.2. Overwhelming freedom of input You don't have to worry about ""recording being too tedious to continue.""The only required field is ""Title""! All other items (author, publisher, volume number, number of pages, purchase location, notes, rating, etc.) are optional. Depending on your style, you can choose between detailed input or quick notes.3. Intuitive tab-switching operation Equipped with dedicated tabs for each phase, such as ""Acquisition Status,"" ""Reading Status,"" and ""Disposed."" You can smoothly switch statuses with a single tap. 4. Never forget ""borrowed books"" or ""lost books"" It allows for the ""return management of borrowed books"" and the recording of ""former collections"" no longer in your possession—features that were difficult to find in existing apps. It leaves no cloud over your reading history. 5. Detailed reading notes and progress management Since you can record ""what page you are on now,"" it is safe even for those who read multiple books in parallel. You can leave plenty of thoughts and favorite phrases in the memo field.■ Main Functions List Book registration/editing: Title (required), volume number, publisher, author, purchase location, total pages, pages read Status management: Acquisition status, acquisition method, reading status, disposal status, book nature (digital/paper) Category display: List display by status using tabs Rating/Comments: 5-star rating and free-form notes Lobby screen: An intuitive portal where information for the entire app is aggregated Recommended for: Avid readers and collectors who want to organize their bookshelves Those who want to clear their ""tsundoku"" (unread pile) and make reading a habit Those who use both e-books and physical books"
