A photo set, not just a photo
Front, back, the tasting card, the box. Roastbook keeps every photo and picks the front as the hero, cropped square and centered.
Roastbook
Your personal coffee journal.
Photograph the bag, let your phone read it, rate it when you know. A year from now, “that roaster with the peach one” is a two-second search.
Coming soonFirst release planned on GitHub Releases, as open source under Apache-2.0.
Android 12 or newer. Free of accounts, ads, and analytics.
What it does
Everything the bag told you, kept after the bag is gone.
Reads the bag for you
Roaster, coffee name, origin, region, producer, process, varietal, elevation, roast date, and tasting notes, pulled from the bag on your phone.
A score that’s fair to mellow coffees
Aroma, flavor, and finish average into one score. Acidity and body describe the coffee without grading it.
Nudges only when you want them
Pick “remind me tomorrow” or “next week” when you add a coffee, and get one gentle second look after you rate it. Nothing more.
Sort, filter, search
Sort by score or any dimension, filter by origin, process, roaster, or where you bought it, and search every note you’ve written.
Backups you control
Android backup brings back your ratings and thumbnails. A daily backup file, with full photos, goes to a folder you choose.
How it reads a bag
On your phone first. The cloud only if you ask.
- On your phone
Text recognition
Reads every word on the bag, fast, on every supported phone.
- On your phone
Gemini Nano
Understands what those words mean, on phones with Android’s on-device AI.
- Optional, your key
Gemini API
A cloud fallback if you add your own key. Off unless you turn it on.
Whatever it reads is a suggestion. Every field stays editable, forever.
Your journal lives on your phone.
No account, no server, and nothing sent to us. Photos and ratings stay in the app’s private storage. The only things that leave your phone are the ones you turn on, and the privacy policy lists every one.
Open source, when it ships.
Roastbook’s first release is planned for GitHub Releases, with its source code under the Apache License 2.0. No store account needed, and anyone can see how it works.
