Books Tracker: Reading Tracker のアプリ分析 5月3日

Books Tracker keeps your personal library organized, beautiful, and always in sync across your devices. No account required. No subscription. Just your books. SYNC ACROSS DEVICES Connect via Google Drive and your entire library stays up to date on every phone or tablet you own. Changes sync automatically in the background — add a book on one device, find it on the other. Your data is stored in a private app-only folder: no one else can see it, not even in your Drive. YOUR WHOLE LIBRARY Add books manually, search online by title, author or ISBN, or scan a barcode with your camera. Every book can carry a cover, rating, reading status, notes, genre, publisher, page count, series info, and more. TRACK YOUR READING Three reading states: To Read, Reading, and Read. Reading start and end dates are recorded automatically. See how long it took you to finish a book — hours, days, weeks, or months. COLLECTIONS & SERIES Organize your books into as many collections as you like. Number them, detect missing entries, manage your wishlist. Group books into series and browse all volumes in one place. READING STACK Your personal "to read next" list. Reorder by drag and drop, move books up or down, and always know what's coming next. FIND ANYTHING FAST Real-time search by title or author. Filter by rating or reading status. Switch between list, compact, and grid view. Everything persists across restarts. MAKE IT YOURS 12 color themes, two header styles (Bold or Subtle), and full light/dark/system mode support. The entire app adapts instantly — colors, gradients, cards, everything. IMPORT & EXPORT Back up your library or move it to another app with CSV export. Import from a file with a full preview before committing — choose how to handle conflicts book by book. No ads. No tracking. No subscription. Books Tracker is built and maintained by a solo developer who loves books.
