BrewFix - Fix Your Cuppa

Coffee tastes off ? Tap the symptoms sour, bitter, weak and get the one science-backed fix for your next brew. Completely free and private.

Your coffee tastes off. BrewFix tells you the one thing to change.

Most coffee apps are recipe libraries. BrewFix is a diagnostic tool. Brew your cup, tell it what's wrong — too sour, too bitter, weak, harsh — and it gives you a single, science-backed fix based on what you actually just brewed.

How it works Brew with the built-in timer. Tap the symptoms that match. Get your fix — one variable at a time. Log it and taste the difference next brew.

Gets smarter over time Every brew you log teaches BrewFix your palate. After a few sessions it knows your sweet-spot temperature, your best dose, and which variables actually move the needle for your setup. The advice gets personal.
