About

ChaJi

Features
Read full description

Cha Ji is a focused tea journal for gong fu cha enthusiasts. Keep a record of every tea you own, every brew you make, and the notes that help you improve, all stored privately on your device and synced via iCloud. JOURNAL Add teas with name, type, origin, vendor, harvest season, star rating, and a purchase link. Log brew sessions for each tea: temperature, leaf weight, water volume, vessel, steep times, and free-form notes. Mark whether you want to buy a tea again. Search and filter your whole collection by type, rating, or buy-again status. BREW SESSIONS Each tea keeps a numbered session log. Record the date, vessel (gaiwan, teapot, or custom), temperature, grams, milliliters, individual steep durations, tasting notes, and a "next time" note to guide your next brew. Session parameters carry over automatically so you spend less time filling in forms. BREWING REFERENCE The Brewing tab shows gongfu starting-point ratios for every major tea style: green, white (tender and aged), yellow, oolong, black, raw pu'er, and ripe pu'er - with temperature guidelines. Dial in your vessel size with the slider and the leaf amounts scale to match. CLEAN AND FOCUSED No accounts. No subscriptions. No social features. Just a well-organized place to keep your tea notes.
