Your entire bookshelf in your pocket. My Library makes cataloging your books a pleasure: point the camera at a book's barcode — one beep, and it's in. Title, author, cover and page count are filled in automatically. No barcode? Search by title, or add it by hand with a photo of the cover. TRACK YOUR READING • Start and finish books with one tap, and see how long each one took • Set the page you're on and watch the progress bar move • See what percentage of your library you've read, and how long it'll take to read it all A SHELF THAT FILLS WITH COLOR Your books appear as spines on a virtual shelf. Unread books stay gray; every book you finish adds color. Share your shelf as an image with one tap. COLLECTIONS Group your books by author and series. See what percentage of an author's best-known works you own, and which volumes are still missing from a series. KEEP THE PASSAGES YOU LOVE Photograph a page and the text is extracted automatically. Crop it to the quote you want, add the page number, done. Mark the best ones to memorize and review them in their own tab. SMART STATS Charts of books and pages finished per week, month or year.

Verdict
The clearest difference is ads: My Library at none against Book Memo's shown. Book Memo's advantage is update cadence (every 2 days vs every 5 days). On price, in-app purchases, device support and iOS requirement there is nothing between them.
