Coffee Can, a Private Notebook for Coffee People

Field notes

Coffee Can records both the variables behind a home brew and the sensory result, including dose, grind, water, pour stages, and eleven flavour axes averaged by bean. Its travel layer distinguishes café cups from home brews and stores a photo, city, and date for places worth revisiting. The site states that the underlying database stays on the phone, with export handled through a file rather than an upload; optional sign-in is reserved for AI features.
