What it is

A tool to understand, record and improve every brew.

  1. 01

    Record

    Every bag with its roaster, farm, process and rest. Every recipe with its grind, water and pours. Nothing stays in your head.

  2. 02

    Brew

    Guided mode runs the phases of your recipe with two clocks, a heads-up before each change and the screen always on.

  3. 03

    Understand

    Sensory bars, TDS and extraction, SCA cupping and per-bean statistics. You see what changed and why it came out better.

Features

Everything that happens between the bag and the cup.

  1. A bean sheet with process, variety, rest window and inventory.
    01

    Beans

    Log every bag: origin, process, variety, roast level, roast date and how much is left. Always know what is on the shelf and how long it has rested.

  2. Recipe list with target ratio, grind and time for each one.
    02

    Recipes and brews

    Write the recipe once, with dose, water, temperature, grind and pours, and log each brew with its result. Iterate on what worked.

  3. Guided mode with the big clock, the current phase and the grams bar.
    03

    Guided brewing

    A timer that calls out each pour of the recipe while you brew, with a heads-up before every phase change and the screen always on.

  4. A grinder sheet with its calibration curve.
    04

    Grinders and microns

    Store each grinder’s calibration curve, tick to microns, and estimate particle size. Includes a micron ruler to compare by eye.

  5. Stats with brews per week and an extraction control chart.
    05

    Tasting and stats

    Sensory bars, score, flavor notes, TDS and extraction, cupping on the SCA form. Then search by bean, method or yield and see your trends.

  • 06

    Offline first, synced

    Everything is saved on your phone first and synced to your account when there is a network. Switch devices and pick up where you left off.

  • 07

    Your data is yours

    No ads, no third-party analytics, no data sales. Export everything to a file whenever you want and delete your account from the app in two taps.

Try it

Try it right here.

Three pieces of the app, exactly as they work on the phone. Move them.

Micron ruler

Pick a particle size and watch the grind change. In the app it is calibrated with a physical card and saves points on your grinder’s curve.

Particle size700 µm
200 µm (fine)1400 µm (coarse)

Approximate visual comparison, not a measurement. Here, at a relative scale.

Extraction

With the dose at 15 g, move TDS and ratio and the extraction yield lands in its zone. The same formula and the same test cases as the app and the API.

Extraction yield
18.9 %

Ideal extraction

Sweet, balanced. Write it down.

From recipe to brew

A recipe is a sketch until it is brewed. The dashed border closes when you run it and the result stays.

Roadmap

What comes next, in order.

No invented dates: each step depends on the previous one, and that is how it gets built.

  1. Shipped

    in production
    • BrewBean for iOSOn the App Store, with real users.
    • BrewBean for AndroidFull parity with iOS, in Google Play closed testing.

  2. In development

    built, awaiting release
    • Profiles by levelHome Barista, Barista or Competitor: the app shows only what you use.
    • Cup Tasters trainingTriangulation under the official 2025 rules, with stats per variable.
    • CVA cuppingThe SCA Coffee Value Assessment form, alongside the classic one.
    • Bag photosStored privately, served through signed URLs.

  3. Next

    planned
    • Share recipesBy link and typeable code, with your handle. No feed: only whoever has the link.needs: the brewbean.app domain
    • Cupper calibrationsOnline sessions with several cuppers, report and CSV.needs: recipe sharing

  4. Vision

    later
    • Public recipes and rankingsThe social layer, when the user base asks for it.
    • CafésList, visits and ranking. The model exists; the interface is missing.

Take it behind the bar.
