Kohii — The Barista Log

Kohii is a calm, beautiful coffee journal for people who care how their cup tastes. Log every brew, track every bag, and slowly dial in your perfect cup — all on a warm, paper-like canvas inspired by the Japanese kissaten. Fully offline, no account, no subscription.

— A coffee brew diary for every method —
Whether you pull espresso, pour over a V60 or Chemex, press an AeroPress or French press, screw together a moka pot, or batch a cold brew, Kohii logs it. Record dose, yield, water, brew time, grind setting, and temperature, and watch your brew ratio calculate live as you type. It's the espresso tracker and pour-over log you've been keeping in a notebook — finally in one place.

— Track your beans —
Build a shelf of every bag you buy. Save the roaster, origin, process, roast date, weight, and price, then watch a gentle freshness countdown tell you when each bag is at its peak. Kohii remembers what you bought, when you opened it, and how it brewed — so your next bag is a smarter choice.

— Rate every cup —
Score each brew across Acidity, Bitterness, Sweetness, Body, and an Overall rating using a tactile bean scale. Over time your coffee diary becomes a personal taste archive — you'll see exactly which beans and recipes you loved.

— Find your best brew —
For every bag, Kohii surfaces your highest-rated cup as its "Best Brew," with the full recipe saved. One tap on "Brew Again" pre-fills a fresh log with those exact settings, so a great cup is repeatable, not lucky.

— A built-in ratio calculator —
Dialing in a new recipe? The ratio calculator works out dose, water, or ratio from any two values — no mental math at the counter.

— Yours, and private —
Kohii is fully offline. Your entire coffee journal lives in a local database on your device — nothing is uploaded, synced, or sold. Back up and restore your log whenever you like, on your terms.

— Simple, honest pricing —
Kohii is free to use. A single one-time Premium unlock removes ads and lifts the shelf limit for unlimited bags. No subscription, ever.

Kohii is the barista log for home baristas, specialty coffee lovers, and anyone chasing a better cup — a quiet, well-made companion for the daily ritual of making coffee.
