Found a brew guide online? Paste the link, or share it to BrewSmart from Safari, and the recipe comes up ready to check and save. Free, no ads, no subscriptions. BrewSmart is your complete coffee brewing companion. Calculate the ratio, get coached through every pour, log the cup, then dial in the next one — and share the winner as a link that opens right in a friend's BrewSmart. All in one fast, focused app. No ads. No subscriptions. Adjust water, coffee, or ratio and the other two update instantly. Perfect for pour over (V60, Chemex, Kalita), AeroPress, French press, moka pot, drip, and espresso — whether you're dialing in a new single-origin or scaling up a batch. THE BREWING LOOP 1. Calculate — Tap or swipe water, coffee, or ratio; the others recalculate instantly. No keyboard, no guessing. Precise to 0.1 g. 2. Brew — Turn any recipe into a guided, step-by-step pour with target weights, timing cues, and a live countdown to your next pour. 3. Log — Save every brew to your journal with a rating, notes, grind, and temperature. Edit any detail later. 4. Dial in — Tell BrewSmart how the cup tasted — too sour or bitter, weak or strong — and get a specific adjustment for your next brew. 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. Start from the built-in pour schedule, or build your own pours with a bloom and custom targets. A live countdown ticks down to your next pour. Or keep it simple with the plain timer. Clip Recipes from the Web Found a brew guide online? Paste the link and BrewSmart reads the recipe off the page: dose, 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 journal entry 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. Recipe Collection Browse a hand-picked collection of recipes — classics like the 4:6 Method, hot and iced — right from the recipes screen, and save any of them into your app. Apple Watch Brew Coach Start a guided brew from your wrist and follow the pour coach with haptic cues for every pour — no need to touch your phone mid-brew. Real-time sync keeps your watch and iPhone together. Home Screen Widgets Jump straight to your ratio or timer. Lock Screen Live Activity Keep your pour timer and next-pour countdown on the Lock Screen and Dynamic Island. Siri & Shortcuts Ask Siri to calculate your ratio or start a brew timer hands-free. Recipe Management Save your favorite water, coffee, and ratio combinations, plus grind and temperature, as named recipes. Attach a coffee, load any setup with one tap, then edit, rename, or delete anytime. Grams or Ounces, °C or °F Switch weight between grams and ounces and temperature between °C and °F — across the app, widgets, and Apple Watch. Clean & Focused No ads. No subscriptions. Light and dark mode. Optimized for iPhone, iPad and Apple Watch. — Whether you're calibrating your V60, dialing in espresso, or just making a better cup every morning, BrewSmart takes you from ratio to perfect brew — and remembers what worked.

Everything BrewSmart does now has a name and a place to find it. NEW: Four tabs Brew, Recipes, Journal and Coffees. The dial is still what you see when you open the app, every time. What changed is the four unlabeled icons that used to sit in the corner: the screens they hid are tabs now, with names on them. NEW: One screen for adding a recipe Tap the plus in Recipes and all three ways in are in one place. Paste a link and BrewSmart reads the recipe off the page. Browse the collection. Or write your own. It also names the way most people never find: share a brew guide to BrewSmart straight from Safari, and the recipe comes up right there. Start brew is a full width button under the dial now, instead of a circle floating in the corner, and it says so when a brew is already running. An import that does not save now tells you. It used to close quietly and leave nothing behind, which looked exactly like it had worked. One you may not have found yet: start a brew from your Apple Watch and the pour coach taps out every pour on your wrist, so you never have to touch your phone mid-brew. Plus reliability improvements and fixes throughout. Still free. No ads, no subscriptions.
