Stop guessing your coffee-to-water ratio. Enter your beans or your water and get the exact amount of the other — down to the gram — for a balanced, repeatable cup every single time. Most brew guides hand you one fixed number. CoffeeRatio calculates both directions, tunes the ratio to eight different brewers, and then times the brew for you so the recipe actually makes it into the cup. It is a scale-companion and a step-by-step timer in one, built for people who weigh their coffee. WHAT YOU GET - Instant two-way ratio math: type your beans to get the water, or your water to get the beans - Tuned ratios, grind size, and water temperature for 8 methods — Pour Over, Chemex, AeroPress, French Press, Espresso, Moka Pot, Cold Brew, and Drip - A step-by-step pour timer that counts you through bloom, pours, and drawdown for each brewer - Strength control — dial the cup from mild to bold and watch the grams update live - Save your dial-ins as named recipes with tasting notes and a star rating, then reload them in one tap - A daily brew reminder and a quick reference for grind, temperature, and steep times PERFECT FOR - Home baristas chasing café-quality coffee without the guesswork - Pour-over and Chemex fans who want a repeatable pour - Espresso and AeroPress tinkerers dialing in a shot - Cold brew makers scaling a batch to the right concentrate WHY NOT JUST USE A NOTES APP OR A CALCULATOR? A calculator does not know that espresso, cold brew, and French press each want a different ratio, grind, and temperature — and it will never time your bloom. CoffeeRatio bakes the method into the math and walks you through the brew, so you get the same great cup whether it is your first pour or your five hundredth. PRIVACY Everything runs on your device.
