Cloudflare‑hosted coffee water chemistry calculator and logbook
It lets coffee enthusiasts compute and track mineral concentrations in brewing water, using a self‑calibrating solver that fits real measurements. The service runs on Cloudflare Workers with D1, KV, R2 and AI integrations for magic‑link auth, photo‑based coffee‑bag parsing, and tasting coaching. Designed for home baristas who want precise, repeatable brew recipes and a shared community logbook. Compared to generic spreadsheets, it offers a turnkey, always‑online UI, automated calibration, and AI‑driven insights.
