BrewSmart: Coffee Ratio

BrewSmart is the fastest way to nail your coffee ratio — and now it guides you through the pour, too. Adjust water, coffee, or ratio, and the other two update instantly.

Perfect for pour over (V60, Chemex, Kalita), AeroPress, French press, moka pot, drip coffee, and espresso. Whether you're dialing in a new single-origin pour over or scaling up a batch brew, BrewSmart does the math in real time so you can focus on the craft.

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 (New)
Turn any recipe into a step-by-step guided brew. BrewSmart walks you through each pour with target weights and timing cues — so you always know how much to pour and exactly when. 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.

Brew Timer
Count-up timer with start, pause, resume, and reset. Time your extraction without leaving the main screen.

Recipe Management
Save your favorite water, coffee, and ratio combinations as named recipes. Load any saved setup with a single tap. Rename or delete anytime.

Apple Watch App
Full-featured companion with real-time sync. Check your ratio and control the timer right from your wrist.

Clean & Focused
No ads. No subscriptions. Light and dark mode. Works in grams for precision. Optimized for iPhone and Apple Watch.
