The Problem

Most brew trackers miss the point

You don't need another app to log what you drank. You need one that helps you brew it better next time. Generic trackers treat every brew as an isolated event. But dialing in is a process — each brew builds on the last. BrewMark is built for that process.

Features

Built for the dial-in

Smart Suggestions

“Try 2 clicks finer.”

After each brew, BrewMark analyzes your extraction feedback and history to suggest your next adjustment. Bigger leaps early in the process, finer tuning as you close in on balanced.

Next Brew

Try 2 clicks finer

Your last brew was under-extracted at grind 20. Moving to 18 should bring out more sweetness.

Rotary Grind Dial

Feels like the real thing

A tactile rotary control with haptic feedback. Spin to set your grind — it clicks like your grinder does. Precise, satisfying, and faster than typing a number.

Extraction Feedback

Under. Balanced. Over.

One tap to rate your extraction. This simple input powers everything — suggestions, history, and knowing when you've nailed it. No five-star scales. No tasting wheels. Just the signal that matters.

Bag-Centric Tracking

One bag at a time

Every brew belongs to a bag. Settings carry forward — your grind, dose, and ratio persist between brews. You only change what needs changing. When you hit balanced, save the winning recipe and move on.

The Loop

Five brews from dialed in

1

Add your bag

Name, roaster, roast level. That's all it takes to start.

2

Brew and log

Set your grind with the rotary dial, enter dose and water.

3

Rate your extraction

Under-extracted? Balanced? Over? One tap tells BrewMark what happened.

4

Get your next move

BrewMark suggests a grind adjustment based on your feedback and history.

5

Mark it dialed in

When you hit balanced, save the winning recipe. Your bag is done.

Settings carry forward between brews. You only adjust what changed.
