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 — Shizuku calculates the ideal pouring schedule automatically. Dial in taste (sweet ⇄ bright) and strength (light ⇄ 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.

■ Detailed Analytics (Premium)
Visualize your coffee life with brewing trends by time of day and day of week, taste & strength preference breakdowns, your Top 3 most-used beans, average ratings, and monthly stats.
