Field service and logistics apps carry a requirement most consumer apps don't: they have to work when the network doesn't. A technician in a basement, a driver between cell towers, a warehouse with patchy wifi — the app can't just fail.
What actually needs engineering around
- Offline-first architecture. Local storage that queues changes and syncs when connectivity returns — not an afterthought bolted onto an online-only app.
- Real-time dispatch and GPS tracking. Job assignment and location updates that stay accurate even on a spotty connection.
- A technician-facing app built for the field. Large touch targets, works one-handed, survives a cracked screen's worth of real-world conditions — not a scaled-down admin panel.
Where the real engineering time goes
Not the UI — the sync logic. Conflict resolution (two technicians editing the same job offline, then both coming back online) is the part that separates a demo from a production system. We've built exactly this pattern — see our field-service platform for a solar installer — real dispatch, offline sync, and a technician app built for actual field conditions.
