Brew Science: Coffee Toolkit

Brew Science puts the tools for grinding, brewing and tasting in one app. No account, no ads; the core tools work without a network connection. ◆ Coffee Brew at home: pick pour-over or espresso, choose your beans and a recipe, then weigh, pour and time it step by step. The grind is converted to your grinder. After the cup, say what's off and get a fix for the next one. Or make a tasting card with the bean details and flavors filled in. Brew a bag again with last time's recipe and dose. Out for coffee: make a tasting card from a great cup. ◆ Scan a bean bag, log it automatically Photograph a bag and the roaster, origin, process, variety, altitude and flavor notes fill in. On supported devices, Apple's servers read the photo and don't keep it. Café info cards scan into tasting cards too. ◆ Brew Calculator Ratio and water planning, a brewing control chart, and extraction yield for cold-brew concentrate. ◆ Espresso Dial-in Yield and a typical time window from your dose and ratio, with fixes for over- and under-extraction. Includes attributed CORE long-extraction protocols; save your own versions. ◆ Grinder Match Pick two grinders; change either side and the other converts (micron-interval based). 8 popular grinders free; Pro unlocks all 121. ◆ Curated Recipes & Staged Timers Staged timers that pour with you, with a sound at each stage and at the finish. They keep running when you leave the page, and show in the Dynamic Island and on the Lock Screen. Save your own recipes too. ◆ Water Lab Four target water profiles plus your own recipes, with GH/KH conversion; mineral data for 135 bottled waters. ◆ Grind Size Reference & Photo Measurement Photo-based D10/D50/D90 measurement against a calibration object, with the full curve. ◆ Bean Cellar & Resting Record each bag's roast info; resting and peak-flavor windows are estimated. You can also set your own dates. Each bag remembers its grinder and setting, and shows how many cups are left. Frozen bags get their own section: days in the freezer don't count, and the window moves out when you thaw them. For a set or a repeat buy, copy a bag and edit it. Rate a finished bag and note your impression; finished bags move aside and stay searchable. Widgets show which bag to drink today and its days left, on the Home Screen, Lock Screen and full screen on iOS 27 (Pro). ◆ Tasting Cards Pick flavors on the wheel and the card is made: 8 styles, optional cupping scores, a bag's details in one tap. Save to Photos or share. ◆ Brew Rescue Cup tastes off? Pick a symptom, get a diagnosis path. ◆ Roast Reference Eight SCA roast levels (Agtron) with their crack stage, flavor and surface oil.
