When technicians lose cell service, Skimmer's offline mode lets them keep working without interruption — they can complete stops, log readings, and take photos even with no signal, and all of that data uploads on its own as soon as they reconnect. This is something pool pros in rural areas rely on, so a poor or missing cell connection doesn't stop a route from getting done.
The offline experience holds up across the parts of a stop a tech touches most. They can swipe to mark checklist items finished with no service, and the live-photo requirement still applies — techs can't upload from the camera roll to get around it, so your records stay accurate. Once a cellular or Wi-Fi connection is back, Skimmer pushes everything collected while out of range, so nothing is lost.
