A gentle journal for the matcha you love.
Matchabook is a journal made for matcha lovers. From the day you open a tin, it helps you record every gram, every note, and every best-by date — and gently reminds you to "drink this one first" before it's past its prime.
■ A file for every tin
Snap a photo, pick the label, and note the date acquired, net weight, and opening date. A built-in catalog of 120+ meisho from 11 storied Japanese makers — Marukyu Koyamaen, Ippodo, Ryuoen, Kanbayashi Shunsho, Nakamura Tokichi and more. Can't find yours? Add it in seconds.
■ Log every bowl in one tap
Usucha, koicha, matcha latte, or dessert — record how many grams you used with a single tap. See what's left in the tin and how many days since opening at a glance.
■ Never miss a date
Matchabook works out the best-enjoyed window after opening and the best-before date while sealed, then sends a gentle reminder the number of days ahead you choose.
■ Home Screen widgets at a glance
Bring your matcha to the Home Screen. Freshness Countdown shows how many days the most urgent tin has left and adds a new tin in one tap; Matcha Shelf lists several tins at once — tap a row for details, tap the pencil to quickly log usage, and choose your sort order.
■ See your matcha year (Pro)
Monthly totals and weekly trends are free. Upgrade to Pro for a yearly review and a top-matcha ranking — see how many grams you drank this year and which label you loved most.
■ Three warm themes · CSV export (Pro)
Switch freely between Persimmon, Hojicha, and Plum. Export your usage log to CSV anytime.
■ Privacy first
Everything stays on your device. No servers, no uploads, no tracking. No sign-up, no login — just open and go.
Available in English, 繁體中文, and 日本語.
