Knows what's on the shelf near you and what it costs. Remembers what you thought of every coffee. Gets sharper with every cup you rate.
The best-rated coffee isn't the best coffee for you.
Two people can agree a coffee is "good" and still want completely different things from it — more body, less brightness, a fruit-forward Ethiopian one week and a dark, cocoa-heavy blend the next. Star ratings average strangers. Arosti learns YOU.
SCAN THE BAG
Point your camera at any coffee — on a store shelf, at a café, in your cupboard. Arosti reads the label, finds the coffee, and tells you how well it fits your taste: Excellent match, Very good, Good, Mixed, or Weak. Then it says why, in plain words, and what to watch out for.
IT LEARNS FROM EVERY CUP
Rate a coffee in seconds. Add what shaped it — loved the fruit, too bitter, great body — and how you made it: espresso, pour-over, AeroPress, drip, with milk, iced. Log the same coffee across different preparations and see which way you like it best. Every cup sharpens the predictions.
YOUR TASTE, MADE VISIBLE
Arosti builds a seven-axis taste fingerprint — Body, Bright, Sweet, Smooth, Nutty, Fruit, Roast — from what you actually rated, and lays it over each coffee's profile so you can see where they meet and where they don't.
HONEST ABOUT WHAT IT KNOWS
Predictions carry their confidence. A first-day guess says so. Arosti never pretends a score is more precise than the evidence behind it.
REMEMBER EVERYTHING
Every coffee you've tried, what you rated it, where you found it, what you paid, and what you wrote about it — in one place, searchable, yours.
DISCOVER
Recommendations built from your own ratings, not the crowd's, filtered to what's actually stocked near you when that's known. Roaster pages, a café map, price per pound, and links to buy direct.
BUILT FOR THE GROCERY AISLE AND THE THIRD-WAVE CAFÉ
Thousands of coffees from national brands and independent roasters, growing with every scan. If we don't know a coffee yet, you can still rate it — and it joins the catalog.
FREE TO USE
No account required to start. Sign in to keep your journal across devices.
Arosti uses AI to read labels and score matches; your ratings and notes stay yours, and we never sell your data. Privacy policy: arosti.app/privacy
Arosti learns your taste and tells you which coffees you'll actually enjoy — not the ones strangers rate highest.
New in this version:
• A quicker start: tap the coffees you already like, or search any of 4,600+, and Arosti starts predicting what else you'll enjoy.
• Dozens of new roasters, including many pouring at this year's SF Coffee Festival, plus local favorites from Austin, Boston and beyond.
Every time you open it: scan any bag on a shelf to see how well it fits you and why, log each cup the way you brewed it, and keep a journal of what you loved, where you found it and what you paid.
