The app
Every coffee worth remembering.
Letterboxd for coffee. A journal for people who love drinking coffee — not another brewing tool for the gear-obsessed. Point the camera at any bag, and a check-in takes about ten seconds.
Oslo to Melbourne, Montreal to Cape Town, Tokyo to Bogotá. The catalog is live data — it grows every week, no app update required.
Every coffee app on the store is built for home baristas: dials, scales, extraction graphs. Cupbook is for the far larger group who simply drink coffee and want to remember what they loved and would buy again.
The design rule that follows: a check-in takes seconds — or it doesn't ship.
Scanning a bag runs Apple's on-device text recognition first and matches against the catalog — for known coffees, the photo never leaves the phone.
AI vision is only the fallback for coffees we've never seen.
Every roaster is added by hand: only their live shelf — no zombie listings — with descriptions translated into English from more than a dozen languages.
Every roaster page links straight to their own shop. Cupbook sends demand to small roasteries and takes nothing.
One-person-one-vote community ratings that can't be gamed. No ads, no feeds, no photo clutter.
A deliberately quiet, Scandinavian-minimal app that respects both the coffee and the person drinking it.
Cupbook is designed and built end-to-end by a solo developer in Berlin. Modern AI-assisted toolchain, tested daily by a community of coffee-drinking friends across Europe — and a catalog team of exactly one, hand-adding every roaster.
