What's New in Arosti
1.0.1
September 26, 2026
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.

FAQ
How does Arosti learn my coffee preferences?
Arosti learns your preferences by analyzing your ratings of coffee cups and the tasting notes you provide. It builds a seven-axis taste fingerprint based on your actual ratings, covering aspects like body, brightness, sweetness, and roast level.
Can Arosti scan any coffee bag?
Yes, Arosti can scan any coffee bag by pointing your camera at the label. It reads the label to identify the coffee and then assesses how well it matches your taste profile.
What kind of recommendations does Arosti offer?
Arosti offers recommendations built from your own ratings, not from crowd-sourced data. These recommendations are filtered to show coffees that are stocked near you, when that information is available.
Is Arosti free to use?
Yes, Arosti is free to use. No account is required to start scanning and rating coffees. You can sign in to keep your journal across devices.

How does Arosti's rating system work?
Arosti provides a match score for each coffee, indicating how well it fits your taste profile: Excellent match, Very good, Good, Mixed, or Weak. It also explains why and what to watch out for.
What happens if Arosti doesn't recognize a coffee I scan?
If Arosti doesn't recognize a coffee yet, you can still rate it. Your rating will then join the catalog, helping to expand the app's database.
