Your complete coffee companion — calculate, coach every pour, log the cup, dial in the next. Now brew in grams or ounces, °C or °F. 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 — 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. No keyboard. No guessing. 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 a built-in template like the 4:6 Method or a 10-pour recipe, or build your own pours with a bloom and custom targets. A live countdown ticks down to your next pour. Prefer to keep it simple? Switch back to the plain timer anytime.

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 to your next brew with one tap.

Brew Journal Log every cup with a rating, tasting notes, grind, and water temperature. Add brews by hand or straight from the timer, and edit any detail later. Your brewing history, all in one place.

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. Check your ratio and control the timer right from your wrist.

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 — glance without unlocking your phone.

Siri & Shortcuts Ask Siri to calculate your ratio or start a brew timer hands-free, and find everything the app can do in the Discover menu.

Share Your Brews Turn any recipe or journal entry into a clean, shareable card.

Recipe Management Save your favorite water, coffee, and ratio combinations — plus grind and temperature — as named recipes. Load any saved setup with a single tap, edit every detail, and your loaded recipe stays pinned to the main screen. Rename or delete anytime.
