Remember the reading life behind every finished—or unfinished—book. Folio is a private reading log for iPhone that keeps your library, timed sessions, page progress, notes, goals, and statistics together without adding a social feed. YOUR PERSONAL LIBRARY • Find books through search or add them manually • Organize reading, finished, want-to-read, and did-not-finish shelves • Keep the title, author, cover, page count, dates, rating, and review together • Start with up to 10 books for free TRACK EVERY READING SESSION Start a timer when you sit down with a book, then save how long you read and where you stopped. Page and percentage progress make long books and partial sessions visible—not only the finish. KEEP THE THOUGHTS THAT MATTER Save private notes, quotations, and page references beside the book that inspired them. Write one sentence or many; Folio does not turn your journal into a public performance. SEE YOUR READING PATTERNS Review reading time, pages, streaks, monthly activity, and annual-goal progress. Use the record to understand the habit rather than race through a leaderboard. MORE WAYS TO READ Use ambient sounds during a session, keep a current book on your Home Screen widget, create optional share cards, and export your library as CSV. PRIVACY-MINDED No account is required. Journal data stays on your device and can be exported as CSV with Folio Pro. There are no followers and no social feed. FOLIO PRO Folio is free to download and supports a library of up to 10 books before upgrading. Optional annual and lifetime purchases unlock unlimited books and the complete experience.

Verdict
The clearest difference is in-app purchases: AudioAmber at none against Folio's 2. AudioAmber also leads on update cadence (daily vs every 4 months) and iOS requirement (15.1 vs 17.0). Folio's advantage is ads (none vs shown). On price and device support there is nothing between them.
