ShelfMark is a quiet book tracker for readers who want progress and reading goals without a social feed. Keep books on to-read, reading, and finished shelves, update pages, and see percent complete, pages per day, and estimated time remaining at the current pace. A daily goal and grace-day streak sit alongside a quote wall with page references and optional photos. Yearly goals and a Wrapped-style view summarize reading activity, while Home and Lock Screen widgets display the current book and progress. The free version supports up to three books and five saved quotes; the developer says core goals, progress, backups, restore, deletion, and widgets remain useful without paying. A one-time Lifetime purchase unlocks unlimited books and quotes, additional statistics, pace plans, and a reading-year PDF. Data stays local without an account.
