BookPine is a free book tracker for readers who like to keep a record of what they read. Log your books, set goals that fit your life, and see real stats about your reading habits. If you're coming from Goodreads, you can bring your whole library with you and pick up right where you left off. There's no subscription and nothing is locked behind a paywall. READING CIRCLES Read a book together with friends or other readers. Start a circle from any book, make it public or private, and choose how long it runs. Members write posts, comment, vote in polls and log their progress as they go. You can hide a post until readers reach a certain point in the book, or until they finish it, so nobody gets spoiled. SERIES TRACKING BookPine builds your series list from the books on your shelves. Each series shows its books in order, how many you've read, and which one comes next. Reading a series in another language? Set the language for that series and your progress only counts the books published in it. You can also mark a series as paused or abandoned. CUSTOM COVERS Don't like the cover on your edition? Change it. Pick one from another edition, upload your own image, or grab one from any web page. Only you see your custom cover, and it shows up everywhere you see that book in the app. READING STATS AND INSIGHTS Track pages, finished books and reading time, with charts for your streak, monthly progress and yearly trends. It's an easy way to see how much you read and what you actually finish. BOOK TRACKER, LISTS AND SHELVES Shelve books as Currently Reading, Want to Read, Read or Did Not Finish. Rate with half stars, write reviews, and make your own shelves and lists. Add a book in seconds by scanning its barcode or searching by title, author or ISBN. READING GOALS AND CHALLENGES Set yearly, monthly or custom goals by books, pages, minutes or authors. Streaks and milestones help you keep the habit going. IMPORT FROM GOODREADS, STORYGRAPH AND LIBRARYTHING Import your books, ratings, reviews and shelves in one go, so your reading history comes with you. TRY IT AS A GUEST Open the app and start tracking without an email address. Create an account later if you want to keep going. AMBIENT SOUNDS Play rain, a crackling fireplace, cafe noise and more while you read. SOCIAL Follow friends, share reviews and see what other people are reading, along with their goals, shelves and wishlists. SHAREABLE BOOK CARDS Turn your current read, a favorite quote, a review or a reading milestone into an image you can post or send to friends. TRANSACTION LOG Keep track of the books you borrow, lend, buy or give away. PRIVATE BOOKS Some reads are just for you. Private books never appear on your public profile.
