BrewSmart: Coffee Ratio

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.
