FEATURES Brew Calculator Tap or swipe water, coffee, or ratio; the other two recalculate instantly. Pour Guide Turn any recipe into a step-by-step guided brew with target weights and timing cues.

Clip Recipes from the Web Found a brew guide online? Paste the link and BrewSmart reads the recipe off the page: coffee, water, temperature, and every pour. Review it before anything is saved. A daily limit applies. Share Recipes by Link Send any recipe as a link. It unfurls with a preview in the chat, and whoever taps it sees the pour schedule, grind, and temperature, then saves and brews it. An attached coffee travels with it, so they can make your exact cup. No BrewSmart? The link opens as a web page. Coffees share the same way, alone or with their recipes. Prefer a picture? Any recipe or brew log becomes a clean, themed card. Coffee Library Keep every coffee you brew: roaster, origin, process, varietals, roast level and roast date, plus your own tasting notes. Attach a coffee to recipes and logged brews, then look back at every cup you made with it. Dial-In Assistant Brewed something off? Mark the taste (sour, bitter, weak, or strong) and BrewSmart recommends exactly what to change next time: grind, dose, ratio, temperature, or time. Apply it with one tap. Brew Journal Log every cup with a rating, tasting notes, grind, water temperature, and the coffee you brewed with. Add brews by hand or straight from the timer, and edit any detail later.
