Session-based reading blocks, per-book quote cards, and a one-tap resume loop—without a login wall or private backend. Book Nook is for readers who want their shelf, habit, and marginalia in one calm place. • Run timed sessions from the Session tab and log each block to history: see minutes and counts for the last seven days and an ISO-week goal you set in Settings. • Curate a personal shelf with status, progress percent, and filters; add books manually or pull bibliographic hints from Open Library when you search Discover. • Save quotes with tags and optional links to shelf titles; filter by tag or by book title substring. • Tune default session length, haptics, and weekly targets—all preferences stay local. Your books, quotes, session logs, and settings are stored on-device. Discover uses the public Open Library API over HTTPS only when you submit a search; there is no account sync and no custom server for your library data. • Quote journal and tag chips keep lines you care about searchable without photo screenshots. • Shelf stats and resume cards highlight what to open next. Made for quiet reading rituals—not feeds, streaks, or challenges. If you want a private reading corner with accountable sessions and saved lines, Book Nook is your nook.
