KOOHI is an app for recording and analyzing your daily coffee experiences, helping you pursue your own “perfect cup.”
From buying beans to brewing and tasting, it logs every step of the process and visualizes patterns in your preferences.
【Main Features】
◆ Detailed bean management
Save every detail about your beans — origin, roaster, roast level, processing method, and more — together with photos.
You can also customize the fields to match how you like to keep records.
◆ Drip timer
It’s more than just a stopwatch.
Based on your adjustments for sweetness, balance, and acidity, and your chosen brew ratio, it automatically calculates a brewing recipe tailored to you.
It provides real-time guidance on pour timing and water volume to help you brew consistently.
◆ Flavor and aroma logging & analysis
Rate each cup on a five-point scale for acidity, bitterness, sweetness, body, and aroma.
As your data builds up, the analytics features reveal trends in your taste, such as ideal temperature ranges and brewing methods that suit you best.
High-rated brews can be saved as “Golden Recipes” that you can recreate anytime.
◆ Cost tracking
By logging bean prices and usage, the app automatically calculates your cost per cup.
You can enjoy your coffee while also keeping an eye on cost performance.
◆ Coffee bean knowledge
Perfect even for beginners.
Includes articles that teach you coffee basics and brewing tips.
