Crema is a small, beautifully-opinionated espresso journal. Photograph a new coffee bag and on-device OCR extracts the details. Track each dial-in attempt — dose, yield, time, grind, taste, texture — and rate the drinks you make (espresso, cortado, iced latte, cappuccino, or your own). As your history grows, Crema suggests starting grind settings for new bags based on your own ratings on similar roasts and learns your profile taste and spend. No app store, no account wall, no tracking, no ads.
