New: share recipes by link — they open right in BrewSmart, coffee details and all. Keep every coffee you brew in one place. 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 any value — water, coffee, or ratio — and the other two recalculate instantly, precise to 0.1 g. 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. Share Recipes by Link Send any recipe as a link — it unfurls with a preview in the chat, and whoever taps it can see the pour schedule, grind, and temperature, then save and brew it. Has a coffee attached? Its details come along, so they can make your exact cup. No BrewSmart? The link opens as a web page. Coffees share the same way — on their own 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 from the Home Screen. 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 one of your coffees, load any saved setup with a single tap, and edit every detail. Rename or delete anytime. Brew Timer Count-up timer with start, pause, resume, and reset — right on the main screen. 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 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.

Log a brew that drifted from its recipe, and BrewSmart now asks what you want to keep. NEW: When your brew changes the recipe Ground a little finer, poured a little more? Log the brew and BrewSmart spots the difference. Just log it, save it as a new recipe, or update the original with the numbers you actually used. Brews that differ are marked in your journal, so you can tell at a glance which cup followed the recipe and which one went its own way. NEW: Ask Siri, hands-free Say "Start a brew with BrewSmart" when your hands are busy, or name the one you want: "Brew 4:6 Method with BrewSmart." Log a cup the same way, or ask for the ratio math. Log Brew and Load Recipe are in the Shortcuts app too, ready to drop into your own automations. NEW: BrewSmart speaks Spanish The whole app, now in Spanish, alongside English, Japanese, and Portuguese. One you may not have found yet: while a guided brew runs, the pour timer and your next-pour countdown sit on the Lock Screen and in the Dynamic Island, so you can follow along without unlocking. Plus reliability improvements and fixes throughout. Still free. No ads, no subscriptions.
