Stock work happens in the yards, and the yards often have no mobile signal — so records of mob moves, treatments, deaths, joining, scanning, marking and weaning were delayed or lost. The farm agent for Andrew (NSW) built an offline-first Progressive Web App into the farm's existing website: after one load it works fully offline, queues entries in the phone's local storage, and syncs automatically the moment signal returns — on reconnect, or simply when the screen is turned back on. No app store, no second login; the site's own long-lived session covers field use.

The paper is a complete, repeatable reference for other farm agents: a service-worker strategy that never caches API calls, deploy-time cache busting, the full local data schema for livestock events, species-aware production workflows for sheep and cattle, and ten hard-won lessons — including the middleware prefix-matching bug and the inline-JSON click-handler bug that cost the most time, and why a clean offline error always beats a cached page.
