ShelfMark vs Iskander

A quiet reading tracker for people who love books more than apps. ShelfMark keeps your reading life in one calm, paper-warm place. Log the page you are on, keep a streak alive, and save the lines worth keeping. No account, no feed, no noise. MADE FOR READERS - Three shelves: to be read, reading, and finished. Move a book with a tap. - Quick page updates with percent complete, pages a day, and time left at your current pace. - A daily page goal beside your grace-day reading streak. - Search your library, filter by genre, and sort by recency, title, author, or progress. - A quote wall with the book, page number, and an optional photo of the page. - A yearly reading goal and Wrapped view with pages, streaks, genres, fastest reads, and monthly activity. - A private Home and Lock Screen widget for your current book, pages today, goal, and streak. - A complete local backup, additive restore, and Delete All My Data control. FREE AND LIFETIME ShelfMark is free for up to 3 books and 5 saved quotes. Reading progress, streaks, daily and yearly goals, search, backup, restore, deletion, and the widget stay useful without paying. A single Lifetime purchase unlocks unlimited books and quotes, the 30-day Reading Pulse, finish-date pace plans, full Wrapped statistics, and the one-page Reading Year PDF. It is a one-time purchase, not a subscription. Existing records always remain readable and editable. PRIVATE BY DESIGN Your reading library stays locally on your iPhone or iPad. No account, no analytics, and no tracking. Widget content uses Apple's private on-device App Group storage and is marked privacy sensitive.
