Offline-first
Offline-first is a design approach where an app works fully without a network connection and syncs data later, treating connectivity as an enhancement rather than a requirement.
맥락 속에서
Offline-first apps store data locally and reconcile it with a server once a connection returns, so the user never has to wait for the network to complete a task. For field and shift work (basements, remote sites, gatehouses, rural locations), this is essential, because the moment of clocking in is exactly when signal is least reliable. It is a common property of well-built progressive web apps.
BriefQR과의 관련성
BriefQR is offline-first: clock-ins and clock-outs are saved on the device and sync automatically when a connection is available, so a punch is never lost to a dead spot.
