spine turns the books you've read into a bookshelf you can actually look at. Search for a book and spine builds its spine: the colours come from the real cover, the thickness from the real page count, and the typography from a library of classic book faces — Baskerville, Didot, Futura, Copperplate and more — so no two shelves look alike. BUILT FROM REAL BOOKS Search across multiple book catalogues worldwide. spine reads each book's cover and measurements, then renders a spine to match. YOURS TO ARRANGE Sort by title, author, or recently added. Mark books as read, currently reading, or want to read — books you're reading get a bookmark ribbon, and ones you haven't started sit quietly at the back. A PRIVATE SHELF Not everything you read is everyone's business. Tap any book to turn it around, showing the page edges instead of the title. It stays that way until you turn it back. DAY AND NIGHT A pale gallery wall by day, deep charcoal by night, where the gold foil on the spines comes alive. SHARE IT Export your whole shelf as a single image, ready to post. NO ACCOUNT, NO ADS, NO TRACKING Your shelf lives on your device. There's nothing to sign up for and nothing to subscribe to. Can't find a book? Add it by hand and spine will render it just the same.

Verdict
The clearest difference is in-app purchases: spine at none against Chapter's 3. spine also leads on iOS requirement (17.6 vs 26.0). On price, ads and device support there is nothing between them.
