The Buddy System
CoffeeBuddy

Log every brew, then let the journal tell you your own taste

Everyone has an opinion about how you should brew. CoffeeBuddy has no opinion at all. It just logs what you actually did, and after a few weeks it starts telling you where your own best cups came from.

The bits worth explaining

Insights, not dashboards

The Insights tab writes sentences: “your best filter brews cluster around 1:16”. It only speaks when a pattern has at least two rated brews on each side and a clear half-star gap, so it stays quiet rather than making things up.

Every method already knows its recipe

Pick AeroPress and the dose, ratio, temperature and step timing are already filled in, along with the grinder and brewer you used last time. The grind box asks for the setting on your own grinder (“clicks on the K6”), because a generic “medium-fine” means nothing. You never start from an empty form at 7am.

Water is a variable too

Eleven community water recipes plus your own, and a calculator that turns a GH/KH target into grams of Epsom salt and baking soda. The water gets frozen onto the brew, so it shows up in your ratings later.

The bag, not just the cup

Every bag has its photo, roast date, process, origin and a cost-per-brew figure, and moves from unopened to open to the freezer (which pauses its age) to finished. Add a rest period the day it arrives and Home marks the ready day on the calendar. Brew it a few times and the bag draws its own freshness curve.
