GrindLab vs BrewCard

GrindLab turns your iPhone camera into a precision coffee grind analyzer. Snap a photo of your grounds and get instant, micron-level particle size measurements — no extra hardware needed. ANALYZE YOUR GRIND Use computer vision to detect individual particles and measure their size distribution. GrindLab calculates median size, uniformity score, fines percentage, and boulders percentage so you know exactly how consistent your grinder is performing. Calibrate with a coin or ruler for real-world micron accuracy. FOUR GRIND PROFILES Dial in for any brew method with built-in target ranges: - Espresso: 170-300μm - Filter/Pour-Over: 400-800μm - French Press: 750-1000μm - Cold Brew: 800-1200μm TASTE-TO-GRIND RECOMMENDATIONS Log how your coffee tastes — sour, bitter, balanced, weak — and GrindLab connects your flavor feedback to your grind data. BREW TIMER & RECIPES Time your brews with step-by-step guidance for V60, Espresso, French Press, and Chemex. Create custom recipes with your own ratios, steps, and notes. Live Activities put your timer on the Lock Screen and Dynamic Island so you never miss a pour. BREW JOURNAL Track every cup. Log your beans (roaster, origin, roast level, freshness), brew parameters (dose, yield, temperature, time), and tasting notes with star ratings. Search and filter your history to spot trends and refine your process over time. COMPARE & IMPROVE Save analyses and compare them side by side. Overlay distribution charts, view delta metrics, and set a baseline to track how grinder adjustments affect consistency. See your stats at a glance: total analyses, percentage in target range, and weekly trends. DETAILED VISUALIZATIONS Color-coded particle overlays show exactly where fines and boulders live in your sample. Distribution charts, histograms, and pie charts make your data easy to understand and share. PRIVACY FIRST GrindLab processes everything on-device. Your photos and data stay on your iPhone.

BrewCard is a coffee recipe notebook, brew timer, and sharing tool for people who care about consistent cups. Record recipes for V60, AeroPress, Origami, Kalita Wave, Hario Switch, Clever Dripper, espresso, French press, Moka pot, OXO Rapid, and custom methods. Save dose, water, ratio, grind, temperature, brew time, tasting notes, roast details, and step-by-step pours. When it is time to brew, run the recipe as a guided timer. Each step can show the pour amount, timing, and notes, so you can follow the recipe without guessing. And if you get distracted live activities will keep your current pour details at glance. Build a personal library of your brews, group recipes by method, roaster, process, or technique, and come back to the cups that worked.
