tracelet_ios

iOS implementation of the Tracelet background geolocation plugin.

This package uses Swift and native Apple frameworks (CoreLocation, CoreMotion, BackgroundTasks, SQLite3) to provide production-grade background location tracking.

Native Features

  • Kalman Filter GPS Smoothing — Extended Kalman Filter implementation (KalmanLocationFilter.swift) smooths raw GPS coordinates using device-reported accuracy as measurement noise. Produces cleaner tracks and eliminates jitter. Learn more →
  • Trip Detection — TripManager.swift tracks motion state transitions to detect trip start/stop. Each trip includes distance, duration, waypoints, and start/stop locations. Learn more →
  • Polygon Geofences — Ray-casting point-in-polygon algorithm in GeofenceManager.swift for arbitrary polygon containment checks alongside circular geofences. Learn more →
