Spine Library

Your reading life, beautifully organized. Spine is a personal library app for readers who want to track what they own, what they're reading, and the insights behind their reading habits. TRACK YOUR LIBRARY Add books with full metadata including authors, translators, genres, and page counts. Organize by ownership (owned, wishlisted) and reading state (unread, reading, read, DNF). Support for multiple copies and re-reads. LOG READING SESSIONS Record when you read, how far you got, and track your progress across multiple sessions. Perfect for readers juggling several books at once. Do this without having to painstakingly indicate how many pages you read every day—we just extrapolate based on page count and days spent reading. CAPTURE QUOTES FOREVER Save memorable passages with page numbers. A daily Quote of the Day surfaces gems from your collection. DISCOVER YOUR PATTERNS Rich analytics reveal your reading pace, genre preferences, and trends over time. See your pages per day, books per month, and how your Fiction vs. Nonfiction reading compares. Sparkline charts visualize your daily activity. SMART COLLECTIONS Currently Reading, Recently Acquired, To-Be-Read, Wishlist, Recently Finished, and Loved This Year—your library automatically organized. YOUR DATA, YOUR CONTROL Full backup and restore. All data stays on your device. Whether you're a casual reader or working through an ambitious TBR pile, Spine helps you read with intention and celebrate your progress.
