Vurr: Espresso Companion - Stop guessing your grind. Start pulling better espresso.

Vurr predicts your grind setting before you pull — using extraction physics, roast profile, bean freshness, and live weather data. Not AI. Not generic advice. Scan a coffee bag. Apple Vision reads the label on-device. The engine outputs a grind number with a confidence tier and a “Why?” breakdown showing exactly what moved it. Cold start on a new bag: drinkable range on pull 1 or 2 instead of pull 8. 49 grinders. 19 brands. 14-day free trial.

Hey Product Hunt 👋 I’m Sri — I built Vurr alongside my day job over the last 4 months. The idea came from a simple frustration: every time I opened a new bag of beans I wasted 6-8 shots just to dial in. I knew extraction science could solve this — roast level, humidity, bean age, shot history all affect where your grind should start. So I built an engine that does the calculation for you. The “Why?” button in the suggestion screen is my favourite feature — it breaks down exactly which factors moved the number and in which direction. No black box. Happy to answer any questions about the extraction science behind it — that’s the part I find most interesting to talk about.
