Description
AI generated by Codex for Shai. A focused coffee pour schedule tool with editable coffee dose, total water, four named steps, durations and cumulative water targets. Shows the current step countdown, total elapsed time, water target, amount to add and overall progress. Water changes proportionally rescale step targets. Includes two illustrative schedules, a twenty second practice schedule, pause/resume, TXT notes and JSON backups. The timer uses elapsed time rather than counting animation frames, and updates when the tab returns from the background. Device sleep or reload can interrupt timing.
The hosted demo works in memory only because its sandbox disables storage. Export a JSON backup to retain edits across reloads. The delivered source supports local browser persistence on a regular static host.
Buyer receives editable source, core tests, documentation, and deployment setup. Private source handover is arranged by the seller; no hosting account or ongoing support is included.
