Your library isn't a spreadsheet. It's an object you love — the spine you cracked, the thick fantasy brick next to the thin poetry paperback, the shelf you rearrange on a Sunday for no reason at all. Spine is a bookshelf for readers who ran out of wall.
Long-press a book and it lifts off the shelf with a soft click. Slide it, and its neighbors shuffle aside. Drop it on any shelf and it lands with a little bounce — like rearranging the real thing, minus the dust.
WHAT SPINE DOES
• Drag anywhere. Books have real spines and real widths; the thick ones are thick. Move them with your thumb.
• Ten shelf themes. Y2K pink, light and dark walnut, dark academia, cottage green, gallery white, candy shop, and more — one tap changes the wood, the light, the whole mood. Your books stay put.
• Shelfies in one tap. Export your shelf as a clean image sized for TikTok and Stories. Your shelf is the post.
• Quiet reading stats. Start a session when you sit down; Spine keeps the pages and the minutes. Point the camera at a page to save the sentence that stopped you. No streak guilt, ever.
• Add a book by hand in a few taps: title, author, and page count, then pick a spine colour, height, and thickness so it looks right on the shelf. Barcode scan and title search are on the roadmap.
FREE TO START
Spine is genuinely usable free: 25 books, one shelf, and three themes, with no ads and no account. Spine+ removes every limit.
PRICING
Spine+ unlocks everything: unlimited books and shelves, all ten themes, reading sessions and stats, quote capture, and the widget. Pick how you'd like to pay:
• Spine+ Monthly — 1 month — $1.99 / month
• Spine+ Annual — 1 year — $9.99 / year
• Spine+ Forever — one-time — $19.99, yours forever
All three unlock the same features. Monthly and Annual are auto-renewing subscriptions: payment is charged to your Apple ID at confirmation of purchase, and each renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your App Store account settings — we never see your card and there's no retention flow. Spine+ Forever is a single $19.99 purchase, no renewal, and it survives reinstalls through Restore Purchases.
YOUR LIBRARY IS PRIVATE
Your shelf lives on your device. No account required, no ads, no selling of reading data. The only thing that ever leaves your phone is a shelfie image you choose to share.
