Offline-First Field Service Mobile App
Cross-platform Flutter app and API backend giving field technicians full functionality in zero-connectivity environments, with automatic background sync.
01The Challenge
A field services company's technicians regularly lost work orders and photo documentation when cellular signal dropped in basements, rural sites, and metal-frame buildings, forcing them to redo paperwork back at the office.
02The Solution
We built a single Flutter codebase for iOS and Android backed by local-first storage, so technicians can complete work orders, capture photos, and collect payment entirely offline. A background sync queue pushes everything to the cloud API the moment connectivity returns.
