What it does
Scan a barcode or search by title — covers, authors, and details fill in automatically.
See which books in a series you own — and spot the gaps at a glance.
A wishlist for books you're chasing, with one-tap buy & pre-order links — even future releases.
Arrange books like your real bookcase — stand them up, lay them flat, decorate with charms.
Your shelves show true‑to‑life spines and decorative sprayed edges — crowdsourced by readers and matched to your books automatically.
Fantasy, Dragons, Cozy, Ocean, Mystery… each restyles your shelves with its own art and mood.
Log what you're reading, keep a TBR, and watch your reading add up over the year.
Why MOBS
Most reading apps only track what you've read. MOBS is a free book-tracking app for the books you own — your real physical, Kindle, and audiobook collection. Build your digital bookshelf, catalogue your home library, follow every series, and never buy a duplicate again. No ads, no subscription, no paywalls.
Standing in a bookshop? Check your whole collection in seconds and stop re-buying books you already own.
A proper catalogue of the books you actually own — physical, Kindle, and audiobook editions in one place.
A genuinely free Goodreads & StoryGraph alternative — no ads, no subscription, no locked features.
Take it with you
Your whole library in your pocket — on iPhone now, Android soon.
Make it yours
Each one restyles your shelves — art, fonts, and mood.
