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. Photograph a variety once and new tins of it reuse your photo automatically.
■ 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.
■ A tool shelf for your chasen and chawan
Catalog your chasen, chawan, chashaku, sieve, chasen stand, chakin and tea caddies — add a photo, note the maker or kiln, the date you got it and what you paid. Record a chasen by the name it actually goes by: shin, kazuho, tsuneho, araho, or 80, 100 and 120 prongs — never forced into a number. Built-in Takayama chasen makers and kilns such as Raku and Hagi; tap a maker to see everything you own from them. Mark pieces In Use, Damaged, Lost or Retired. Five tools free, unlimited with Pro.
■ 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.
■ Seven themes · CSV export (Pro)
Switch freely between Fresh Matcha, Grounded Earth, Soft Berry, Classic Ink, Quiet Mauve, Vintage Parchment, and Warm Rose. Export your usage log to CSV anytime.
