GrindLab vs Brew Coach

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. No account required. No tracking. Whether you're a home barista chasing the perfect espresso or a pour-over enthusiast dialing in a new bag, GrindLab gives you the data to brew better coffee every day.

A quiet coach for slow coffee. V60, Chemex, Kalita, AeroPress, French press, and overnight cold brew - each filter method with its own dedicated timer, ratio calculator, and step-by-step pour schedule. Built around the rituals that filter coffee deserves: V60 cones with a bloom and three pulse pours, Chemex with a slower drawdown, Kalita Wave flat-bottom for evenness, AeroPress with the right plunger pace, French press steeped to the second, and a 12 to 24 hour cold brew that lives on your Lock Screen until morning. Why home baristas choose this over a stack of browser tabs: - Apple Watch advances the next pour with a haptic tap when fingers are wet - Live Activity tracks the long cold brew steep on the Lock Screen and Dynamic Island - Each method has its own ratio default, customizable to grams or ounces - Bean log remembers what worked: photo, roast, grind, water temp, tasting notes - iCloud sync keeps recipes and history across iPhone and Apple Watch - No signup, no account. Brewing, methods, Apple Watch and iCloud are free; one-time Lifetime unlock for bean log and custom recipes. Whether the morning is a single V60 by the window or the fridge is filling with a slow overnight cold brew, the timing stays tight and the ritual stays yours. Brew Coffee Timer & Recipe is available for iPhone and Apple Watch.
