You nailed the perfect cup once — and couldn't do it again.
Grind by eye, time from memory, notes across three different apps. Without a structured record, every good coffee is an accident you can't reproduce.

Logging[ feature.02 ]
Extractions you can actually repeat.

Calibration[ feature.03 ]
Your next adjustment, from your own data.
The app reads your history — EY%, TDS, ratio — and suggests the next move: grind finer, raise the dose, shorten the time. You steer by taste; the numbers refine.

// manifesto & design philosophy
Precision over decoration.
BeenCofffe is an instrument, not a feed. Tabular numerals that don't jitter, controls within thumb's reach, offline by default. The tool disappears into the brew — what's left is a better, repeatable cup.

Frequently asked questions
Detailed information on methods, offline functionality, inventory handling, and technical data calibration.
[ helpdesk_support || online_docs ]
[01]Is BeenCofffe free?
You create your account and start logging extractions at no cost. No card required to begin.
[02]Do I need an internet connection?
No. The app is offline-first: everything works on the counter and syncs itself when you reconnect.
[03]Does it work for espresso and filter methods?
Yes. Espresso, V60, Aeropress, and more — the parameters and ratio adapt to the method you use.
[04]Is my data mine?
It is. Your history stays in your account and syncs across your devices. No social feed, no public recipes.
[05]Do I need a scale or special gear?
A scale accurate to 0.1 g helps a lot, but you can log with whatever you have. The more precise the data, the better the suggestion.
