Beanconqueror

Beanconqueror builds a personal coffee dataset from the variables people usually forget. A brew can link a bean, grinder, preparation method, water profile, ratio, temperature and tasting result; compatible Bluetooth scales and pressure devices add live curves. The same app can track green inventory and home roasts, then transfer roasted batches into brewing records. It runs on iOS and Android, supports multiple languages, permits extensive field customization, and is free open-source software. Export and backup options reduce dependence on one phone.

More fields do not automatically produce better coffee. Hardware integrations vary by device and operating system, manual entries can drift in units or naming, and reviewing graphs still requires sensory judgment. The optional bring-your-own-key bag scanner also deserves a privacy and cost check before use. Beanconqueror is most valuable when a user chooses a small repeatable set of measurements rather than recording everything available. Its strength is continuity from green bean to cup, not an algorithm that declares one recipe correct.
