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.

Verdict

The call

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.
