Shizuku - Brew Timer

Brew better pour over coffee at home — every single cup.

Shizuku is a hand drip timer & logging app built around Tetsu Kasuya's famous "4:6 Method." It guides each pour with sound and vibration cues, so even beginners can brew like a barista with consistent, repeatable results.


[Perfect for you if...]
- You're new to pour over and your brews aren't consistent
- You want to practice the 4:6 method right from your phone
- You'd love to save your favorite recipes and bean details
- You want to look back on your coffee habits with real data

[Guided 4:6 Method Timer]
Just enter your coffee dose and water amount, and Shizuku calculates the ideal pouring schedule automatically. Dial in taste (sweet to bright) and strength (light to strong) across 5 levels to match your mood. Each pour is announced with sound and vibration.

[Recipe & Brew Logging]
Save your brew settings, ratings, bean info, and notes all in one place, then recreate "that perfect cup" anytime. Daily brew counts and streaks are tracked automatically.

[Coffee Bean Management]
Log purchase date, price, weight, roast level, and roast date to keep your bean stock and buying history organized.
