Mythmark helps you choose what to read next, remember what mattered, and understand your reading taste - without turning books into a popularity contest. A SCORE THAT SAYS MORE Rate each finished book across ten factors: Prose, Characters, Dialogue, Plot, Pacing, Setting, Atmosphere, Depth, Originality, and Enjoyment. Mythmark brings them together in a clear score out-of-five and builds a personal taste profile from the books you finish. A LIBRARY WITH DIRECTION Your Library is more than a pile of covers. Mythmark ranks what is waiting using your scorecards, reading history, preferences, and intent. Organize your books, pause a pick for later, filter by author or genre, and reorder the shelf whenever you want. PICK THE RIGHT EDITION Search by title, author, or ISBN, or scan a barcode to add the exact edition in your hands. Review available editions, select the cover and metadata that match your copy, add a book manually, or import your Goodreads library from CSV. KEEP WHAT STAYED WITH YOU Write notes, save quotes, and scan a printed page to turn its text into a selectable snippet. Notes and snippets stay attached to the book, ready when you want to revisit or share them. SEE YOUR READING STORY Log pages and reading sessions, track current reads, mark books as finished or Did Not Finish, and record re-reads. Set annual book and page goals, follow streaks and cadence, explore favorite authors and genres, view your ten-factor Mythmark profile, and create shareable monthly or yearly recaps. PRIVATE BY DESIGN No account is required. Your library, scorecards, notes, snippets, sessions, and goals are stored on your device. Page recognition happens on your device, and source images are not retained. Your reading data leaves only when you choose to export or share it. Backup tools keep you in control when moving devices or reinstalling. Read with intention. Remember more. Let every finished book sharpen what comes next.

Verdict
The clearest difference is in-app purchases: Mythmark at none against Readingo's 1. Readingo's advantage is ratings volume (118 vs 4) and device support (3 vs 1). On price, rating and ads there is nothing between them.

Both are free to download. Readingo sells 1 one-off in-app purchase. Mythmark asks for nothing beyond the download.
Mythmark holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Readingo has 118 ratings behind it against 4, so its average is the more settled of the two.
