Book, track and manage your transportation needs with just a few clicks. Our solution is tailored to your specific needs, whether you're transporting goods, employees or clients.

Kōhi is a minimalist brew journal for specialty coffee enthusiasts who brew manually with V60 pour-over. SCAN & ADD Point your camera at a coffee bag — AI reads the label and fills in the details. Origin, roaster, process, roast level — all extracted automatically. Or enter manually if you prefer. BREW WITH GUIDANCE Pick a recipe, tap brew, and follow the step-by-step timer. Each step shows exactly how much to pour, your target scale reading, and the flow rate. A 5-second countdown gives you time to prepare. TEMPLATES & RECIPES Start fast with built-in V60 templates — Standard 3-pour, Gentle 2-pour, and Pulse 4-pour for both 1 and 2 servings. Create your own templates from recipes you love. TRACK BEAN BATCHES The same bean from different roast dates brews differently. Track each bag as a separate batch with its own roast date and freshness window. RATE & IMPROVE After each brew, rate it. Log extraction, body, and flavor notes. AI analyzes your history and suggests one small change to try next time — a degree hotter, a gram more — always within safe bounds. RECIPE VARIATIONS Each recipe can have multiple variations. Try an AI suggestion, compare it to your baseline, and promote what works. Variations lock after brewing so your data stays clean. EXPERIMENT WITH PURPOSE The app suggests experiments based on your brew patterns. Under-extracting? It might suggest a higher temperature. Dialed in perfectly? Time to try something new. One variable at a time, backed by your actual data. DESIGNED FOR FOCUS Clean, minimal interface inspired by Japanese coffee culture. Warm amber tones, no clutter. The brew screen shows only what matters — your current step, scale target, and countdown. PRIVACY FIRST No accounts required to start — sign in with Apple optionally to sync across devices. No ads, no tracking, no data sold. Free. No subscriptions. No ads. Built by a V60 coffee lover, for V60 coffee lovers.
