Coffee Ratio Calculator vs BrewPrint

Whether you are making a cup of coffee for yourself or you are brewing a batch to share with friends, this easy to use app delivers results every time. We built this app both for the coffee aficionado and for those just getting started in the wonderful world of coffee. Just answer these two questions and the app will do the rest: 1) How much coffee would you like? 2) How are you brewing this coffee?

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.
