What can you build with Polyfence?
Polyfence is the geofence layer. Build a product on top, or use a reference tracker as-is. Same platform, two on-ramps.
Fleet & delivery management
Delivery companies need to know when drivers enter or leave zones — warehouses, customer areas, restricted zones — without draining device batteries. Polyfence zones define delivery regions, and the Flutter SDK triggers events on entry/exit. Auto-sync keeps zones updated as routes change.
Livestock & agriculture
Farmers need to monitor when animals leave designated grazing areas or enter restricted zones, often with poor connectivity. Polyfence zones define paddocks and restricted areas. The on-device geofencing engine works offline, and zone changes sync when connectivity returns.
Security & perimeter monitoring
Security companies need to define protected perimeters and get instant alerts when boundaries are crossed. Polyfence polygon zones map to physical perimeters, and the native SDK provides sub-second triggering. Multiple API keys support different security teams.
Compliance zones (ULEZ, LEZ, congestion)
Drivers need to know when they enter low-emission zones, congestion charge areas, or restricted driving zones to avoid fines. Polyfence zones map regulatory boundaries, and the SDK alerts drivers in real-time. Zone data updates automatically when regulations change.
Location-based experiences
Apps want to trigger content, offers, or actions when users enter specific areas — retail, tourism, events — without building geofencing from scratch. Polyfence provides the infrastructure: define zones via the map editor or API, and the SDK handles all platform-specific logic.
Family & personal safety
Parents want to know when children arrive at or leave school, home, or other trusted locations. Polyfence zones define trusted locations, and the lightweight SDK runs in the background with minimal battery impact. Entry/exit events trigger notifications.
