Chasen: Matcha Latte & Tea Log
Diary, timer, caffeine tracker
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Your daily matcha ritual in one app: a zen whisk timer, a ratio calculator that fixes bitterness, and a tasting diary that remembers every cup.
Chasen is the quiet companion for everyone who takes matcha seriously - a tasting diary, a brewing assistant, and a daily ritual, in one calm app.
REMEMBER EVERY CUP
Keep a beautiful diary of every matcha you try: brand, grade, origin, preparation, flavour notes, a photo and your rating. Stop losing track in spreadsheets and Notion templates - Chasen is built for exactly this.
BREW IT RIGHT
A ratio calculator gives you the exact powder, water and milk for usucha, koicha, latte or iced - plus the right water temperature, so it never turns bitter or clumpy again.
A RITUAL, NOT A UTILITY
The zen whisk timer turns brewing into a small moment of calm: a breathing rhythm, a gentle foam animation and haptics guide your whisk strokes. Build a streak of days with a cup.
LEARN THE BASICS
A beginner's guide covers ceremonial vs culinary, real vs fake, how to sift, and how to fix bitterness.
PREMIUM
Unlimited diary entries, iCloud sync, taste insights, the full brand database, a cafe map in key cities, calming themes and CSV export.
Quiet premium design. No clutter, no noise - just you and your matcha.
