BrewFix - Fix Your Cuppa

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. **What's inside** - Dial-In Engine — maps taste symptoms to extraction science (SCA Gold Cup standard) - Built-in brew timer with haptic milestones - Caffeine estimator — calculates mg from your actual dose and temperature - Roast date tracking — flags when stale beans might be the real problem - Brew log with notes, ratings, and CSV export - Insights — your sweet-spot temp, dose, and improvement trend over time - 60+ grinder models with AeroPress click ranges - Supports AeroPress, Pour Over, French Press, Moka Pot, Cold Brew, Clever Dripper, Siphon - Beautiful in light and dark — designed like a roastery, not a dashboard - 100% free.
