Question 1

What is Crema?

Accepted Answer

Crema is a free espresso journal and coffee-logging progressive web app. Log every coffee bag with a photo, rate espresso, cortado, iced latte, and cappuccino, and get tuned grind suggestions based on your past ratings.

Question 2

Is Crema free to use?

Accepted Answer

Yes — Crema is completely free, ad-free, and has no tracking. There's an optional Buy Me a Coffee link if you'd like to support development.

Question 3

Does Crema work offline?

Accepted Answer

Yes. Crema is a Progressive Web App with a service worker that caches the full app shell. You can browse previously loaded bags, view ratings, and read your journal offline. Saves sync when you are back online.

Question 4

How does the OCR work?

Accepted Answer

OCR runs entirely in your browser using Tesseract.js. Photograph the coffee bag and Crema pre-fills brand, origin, roast level, and weight. Photos never leave your device during scanning.

Question 5

Can I install Crema on iPhone or Android?

Accepted Answer

Yes. On iPhone, open crema.live in Safari, tap the Share icon, and choose Add to Home Screen. On Android, open in Chrome, tap the menu, and choose Install app. It launches standalone with its own icon.

Question 6

What is a dial-in log?

Accepted Answer

A dial-in log is the recipe you used to brew a specific shot — dose (grams of coffee), yield (grams of espresso), shot time (seconds), grind size, and taste notes. Crema tracks every attempt so you can see which combination nailed that bag.
