Shizuku is a coffee timer app built around the "4:6 Method" — the pour-over technique created by World Brewers Cup Champion Tetsu Kasuya.

About the 4:6 Method A brewing approach where the first 40% of the water shapes the flavor, and the remaining 60% dials in the strength. Its scientific precision lets anyone pull a consistently delicious cup.

Simple Controls Just set the beans, water, and pour intervals. The app calculates the optimal recipe in real time.

Accurate Timing Start with a 3-second countdown. Sound and vibration cues guide every pour, so you can brew accurately without even looking at your phone.
