About These Tools
Each tool on this page is built around a specific calculation that home baristas use regularly — ratio targeting, shot timing, maintenance scheduling. They run entirely in the browser: no data is collected, no account is required, and results are available instantly. The underlying methodology is documented in the editorial block of each tool page.
Tools are updated when the underlying reference data changes. If you find a discrepancy or want to suggest a tool, use the contact page.
