BEANCONQUEROR

Product Introduction

1. BEANCONQUEROR is a free, open-source coffee tracking app designed to optimize brewing processes by enabling users to log detailed parameters, manage coffee beans, and connect with Bluetooth-enabled devices like scales and refractometers.
2. The app’s core value lies in its ability to combine precision brewing analytics with complete transparency, offering GDPR-compliant data storage, offline functionality, and community-driven development to empower coffee enthusiasts at all skill levels.

Main Features

1. The app integrates with over 15 Bluetooth scales (e.g., Acaia Pearl, Decent Scale, Hiroia Jimmy) and devices like pressure sensors or refractometers, enabling real-time tracking of weight, flow rate, and extraction metrics during brewing.
2. Users can customize 30+ brewing parameters—including grind size, water temperature, bloom time, and pressure profiles—for methods like espresso, V60, and Aeropress, with automatic timer triggers for scales and espresso machines.
3. A dedicated bean management system allows tracking of roast dates, origins, and processing methods, while a water recipe builder lets users input mineral content (e.g., 70ppm magnesium, 150ppm bicarbonate) to replicate optimal brewing water.

Problems Solved

1. The app eliminates manual logging inconsistencies by automating data capture from connected devices and providing structured templates for repeatable brew workflows, reducing human error in parameter recording.
2. It serves specialty coffee professionals, home baristas, and roasters who require granular control over extraction variables and long-term trend analysis via consumption statistics (e.g., monthly coffee spend, brew success rates).
3. Typical use cases include dialing in espresso shots using pressure-profiling tools like the Pressensor, replicating competition-winning pour-over recipes, and managing inventory across multiple coffee batches with roast-level freshness tracking.

Unique Advantages

1. Unlike subscription-based apps (e.g., Brew Timer, Coffee Journal), BEANCONQUEROR offers zero paywalls, ads, or data monetization, with all code publicly auditable on GitHub and infrastructure costs openly disclosed.
2. Innovative automation includes tare-on-timer-start for scales, espresso shot auto-stop based on weight thresholds, and a "freeze function" to pause live brew graphs for troubleshooting without data loss.
3. Competitive differentiation stems from supporting the broadest range of devices (32+ scales, 4 pressure sensors, 2 refractometers), GDPR-compliant local data storage, and crowd-translated UI in 13 languages, including Japanese and German.

Frequently Asked Questions (FAQ)

1. Is BEANCONQUEROR truly open-source? Yes, the app’s full source code is available on GitHub under the Apache 2.0 license, allowing developers to audit features, contribute improvements, or self-host modified versions without restrictions.
2. How do I sync data between devices? Currently, syncing requires manual backups via JSON exports due to offline-first design; cloud sync is delayed due to server cost constraints and technical challenges in reconciling device-specific calibration data.
3. How can I support the app’s development? Users can donate via Ko-fi, contribute code translations (e.g., adding new languages via Weblate), or purchase affiliate-linked scales like the Bookoo Mini using the discount code "beanconqueror" to fund server costs.
