Brew Journal: Coffee Notes Pro

Elevate your daily extraction and master your specialty coffee workflow with Brew Journal.

Brew Journal is an offline-first, professional coffee companion designed to help home brewers, coffee hobbyists, and baristas log, analyze, and master their daily extractions. This app does not lock you into rigid templates; instead, it serves as a analytical canvas to record variables, track consistency, and explore sensory flavor mapping over time.

Whether you brew with a Pour Over, Espresso machine, Aeropress, French Press, Moka Pot, or Cold Brew, Brew Journal records every detail of your setup to guide you to the perfect cup.

⚙️ Premium Barista Features:

Dynamic Sensory Mapping (Radar Charts): Use our custom, interactive pentagon chart to visually map five key flavor indicators: Aroma, Acidity, Sweetness, Body, and Aftertaste (Finish). Pinpoint what makes your favorite extractions shine.

Integrated Barista Ratio Calculator: Effortlessly lock or dynamically calculate brewing ratios (e.g., $1:15$ or $1:16.6$). Enter your coffee weight, and watch the target water volume adjust automatically, or vice-versa.

Smart Bean Cupboard Inventory: Keep track of your custom specialty coffee bags, roasters, price, and origin regions. Built-in roast-date tracking alerts you to optimal degassing windows (fresh degassing phase, peak extraction flavor, and aged bean periods).

Live Extraction Stopwatch & Timeline: Time your brews with a highly visual, phase-aware stopwatch. Get real-time, dynamic suggestions for bloom cycles, active pouring segments, and final drawdowns based on your target water weight.

Barista Cost & Yield Analytics: Track how much you spend per brew. The app calculates your exact cost-per-cup based on the weight of the coffee used and the price of your bags.

Extraction Diagnostics: Instantly evaluates whether your extraction is balanced, over-extracted (bitter/dry), or under-extracted (sour/weak) based on your grind size, temperature, and brew time.

Aesthetic Customizations: Experience fluid navigation with light/dark theme modes, density spacing layouts, custom accent colors (Mocha, Matcha, Terracotta, Caramel), and dual temperature scale options ($^\circ\text{C}$ and $^\circ\text{F}$).
