Pull the perfect shot.

Estratto is a dial-in journal for manual lever espresso machines. Log every shot, capture the pressure curve, and let the algorithm suggest your next adjustment.

100% private — your data stays on your device.

How it works

Log your bean

Roaster, origin, process, roast date. Estratto adjusts baseline parameters automatically for the roast level.
Pull and tap

While the shot runs, tap your pressure on the 1-9 bar scale at 5–15 intervals. No sensors, no hardware — just your finger.
Rate the taste

Balanced, sour, bitter, channeling, or muted? The algorithm immediately recommends your next adjustment: grind, dose, ratio, or temperature.
