No data collection. Just coffee math. HOW IT WORKS Pick a brew method — pour-over, Chemex, French press, espresso, cold brew, drip, or AeroPress — and it loads with the standard ratio. Type in how much coffee you have or how much water you want, and the app calculates the rest. Adjust the ratio with a slider if you like it stronger or lighter. FEATURES Works in grams, milliliters, cups, fluid ounces, tablespoons, and ounces — use whatever you’re comfortable with Bi-directional calculation — start from coffee or water Method presets — pour-over (16:1), Chemex (16:1), French press (15:1), espresso (2:1), cold brew (8:1), drip (17:1), AeroPress (15:1) Adjustable ratio slider — fine-tune to your taste Brew guidance — temperature, grind size, and brew time for each method, adjusted by roast type Save favorites — store your go-to recipes for one-tap access Dark mode — for early morning brewing sessions PRIVACY FIRST Sixteen to One is completely offline.
