Most reading apps are a catalog, a feed, or both. ReadLog is the opposite: a quiet, private place for your reading — the books, the quotes you want to keep, and a recap you'll actually want to look back on. Save the lines worth keeping Type a quote or scan it straight from the page with your camera. Tag it to the book, add the page, mark a favorite. Your highlights live in one searchable journal — not locked inside an e-reader. See your reading add up Books finished, pages read, your reading pace and streak, top genres, books by month. Set a yearly goal and watch it fill. Every number reflects only what you've logged. Make a Reading Wrapped — anytime Turn any month, year, or single book into a beautiful recap card and share it in a tap. Not once a year — whenever you finish something you're proud of. Your library, your shelf Track every book through to-read, reading, finished, did not finish, and reference. Log sessions as you go and see each book fill up. Private by design No account. No AI. Not tied to Amazon or any store. Everything stays on your device — nothing is uploaded, synced to us, or sold. Free — no account needed Unlimited books and shelf, reading sessions, ratings, basic stats, and a yearly recap card. Premium — 7-day free trial, then $6.99/month or $39.99/year - Reading Wrapped for any month, quarter, year, or single book, plus extra card styles - Unlimited quotes and camera quote scanning - Reading goals and full stats & trends - Reading-log PDF export and full library backup - Cancel anytime from your Apple ID settings ReadLog is a personal reading journal.
