Android
Kotlin SDK with FusedLocationProviderClient, foreground service, Room persistence, and a Kotlin Flow API. Min SDK 24.

Beekon
Background-first location SDKs for Android, iOS and Flutter. Three native implementations, one normative spec, byte-for-byte parity verified by GPX replay.
What Beekon does
Section titled “What Beekon does”Three things, on every platform: location capture, background execution, and a persistent history buffer. Locations come through raw — FusedLocationProviderClient on Android and CLLocationManager on iOS already smooth signals — so Beekon adds no Kalman filter, no outlier rejection, no speed clamp on top.
Persistence lives entirely inside the native library (Room on Android, GRDB on iOS). Writes never cross into Dart or JavaScript, because in background those runtimes are not guaranteed to be alive.
iOS
Swift package using CLLocationUpdate.liveUpdates on iOS 17+ with a CLLocationManager fallback for iOS 15–16. GRDB persistence, Swift AsyncStream API.
BeekonKit via SwiftPM
Flutter
Dart plugin — Pigeon-generated MethodChannel + EventChannel over the native libraries. The plugin never participates in the write path.

Three battery presets
Section titled “Three battery presets”| Preset | Distance | Interval | Battery | Use case |
|---|---|---|---|---|
| Saver | 150 m | 60 s | 3–8 % | Passive background tracking |
| Balanced (default) | 100 m | 30 s | 5–10 % | General tracking |
| Precision | 30 m | 10 s | 15–25 % | Active foreground use |
Custom overrides accepted on every preset — see Presets & overrides.
Pick a path
Section titled “Pick a path” Quickstart Install, configure, start tracking — one page, every platform.
Concepts States, gate, positions, persistence, background execution.
Spec (for contributors) Normative behavioural contract — preset values, state machine, gate algorithm, schema, retention.
