BrewPrint vs Cold Brew Studio

Better coffee by design. BrewPrint is a precision brewing calculator for people who grind and brew their own coffee. Set your ratio and BrewPrint does the math, keeping water, coffee, and ratio in balance. Then brew along to a timer built for your method: a simple count-up timer free, or a full guided staged timer with Pro. THE RATIO CALCULATOR (free) • Water, coffee, and ratio as one connected equation. Adjust any value and the other two update instantly. • A precise drag-to-adjust scale with haptic ticks, or tap to type an exact number. • Sensible ranges for real brewing: water 50–2000g, coffee 5–200g, ratios from 1:2 espresso to 1:20. • Weights are always in grams to match your coffee scale; switch temperature between Celsius and Fahrenheit any time. BREW METHODS (free) • Curated, ready-to-brew recipes for V60, Chemex, AeroPress, French Press, Espresso, Moka Pot, and Cold Brew — each with a sensible default ratio and stage timings. • An on-demand prep guide for each method: what gear you need and how to set up, step by step. THE BREW TIMER • Free: a clean count-up timer for any brew. • Pro: a full staged timer driven by your recipe. Each step — bloom, pour, wait, drain — shows as a proportional arc on the ring, with the target weight and instruction for that stage, and a water-level gauge that rises and draws down as you go. BLUEPRINTS (Pro) • Save any recipe as a named Blueprint: method, ratio, water, coffee, grind size, water temperature, timed steps, notes, and a star rating. • Load a Blueprint to set everything at once. Pin one as the default for its method so it's ready the moment you open it. THE PANTRY (Pro) • Track the coffees you brew: roaster, roast level, roast date, taste notes, and a star rating. Only the name is required, so adding a bag takes seconds. • Roast-aware freshness tells you when a bag is resting, at its peak, or going stale, so you know what to reach for and when to reorder. • Attach a coffee to any brew to build a per-bean history, and filter your Brew Log by coffee or roaster. BREW LOG (Pro) • Keep a history of the brews you've made, so you can repeat the good ones and learn from the rest. ICLOUD SYNC • Your Blueprints, brew log, and settings sync privately across your iPhones through your own iCloud account. No BrewPrint account, ever — and we never see your data. BREWPRINT PRO • A single one-time purchase unlocks the full staged timer, unlimited custom Blueprints, the Brew Log, the Pantry, and custom app icons. Try the staged timer free before you buy. Designed to feel like a technical drawing — blueprint grid, monospaced readouts, nothing you don't need. No account, no ads, and it works completely offline. Your morning brew isn't a good time to load a spinner. Better Coffee By Design.

Cold brew is forgiving right up until it isn't. A setting that tastes great on one grinder turns to sludge on another, and the batch you nailed last month is a guess by the time you open a new bag. Cold Brew Studio is a digital studio for the gear on your counter. Tell it what you grind with and what you brew in, and it works out the recipe for your exact setup. Then it helps you dial in every bean you buy. YOUR SETUP ON ONE SCREEN Brew shows your grinder's dial with the setting marked, the grams of coffee and milliliters of water for your batch, and your bag of beans standing next to your brewer. Tap the dial, the bag or the brewer to change it. When it looks right, hit Start steeping. 80+ GRINDERS, RESEARCHED AND DRAWN More than 80 of the most popular grinders were researched and drawn, giving you a full digital studio for your gear. Each one wears its real dial, whether yours has a knob that turns or a numbered ring that rotates past a mark. The cold brew setting starts from the manufacturer's guidance and what the coffee community has worked out. Found your own sweet spot? Drag the dial to where you actually dialed in and the recipe follows. Using something rarer? Add it as your own grinder. SIZED TO WHAT YOU BREW IN Twenty brewers are built in, from a quart mason jar up to a gallon dispenser, and you can add your own by its capacity. Every batch is sized to what your brewer actually holds. Pick a strength: Everyday, Strong, Jet fuel or Concentrate. If your brewer came with its own recipe, that's on the list too. ANY BEAN, READY TO GO Search more than 300 beans from specialty roasters, or scan the label on your bag and the app fills in the bean for you. KNOW WHEN IT'S READY Start steeping and watch your brewer darken hour by hour. The batch lives on your Lock Screen and in the Dynamic Island, with a notification when it's ready to taste and another before it steeps too long. Ask Siri what's steeping, or start a batch by voice. DIAL IN EVERY BEAN Rate each batch and tap what was off, like too weak or too bitter, and the next recipe adjusts. Every bean you brew gets a bag on your shelf, with your rating on the plank below it. Tap a bag for its field notes: your tasting notes next to what the bag promised, with every brew of that bean underneath. Once a bean is dialed in, its best recipe is one tap from brewing again. YOURS Your journal lives on your device, and you never need an account. If you want one, it syncs your journal between your iPhone and the web app at coldbrew.studio. There are no ads or trackers, and your data is never sold. Brew something worth waiting for.
