The most sophisticated background location-tracking & geofencing SDK with battery-conscious motion-detection intelligence for iOS and Android.
The SDK uses motion-detection APIs (accelerometer, gyroscope, magnetometer) to detect when the device is moving or stationary:
- Moving — location recording starts automatically at the configured
distanceFilter(metres) - Stationary — location services turn off automatically to conserve battery
Important
This is v9. For the previous version see v8.x. v8.x license keys do not work with v9 — log in to the Customer Dashboard to generate a v9 key. See the Migration Guide for details.
Tip
The SDK is fully functional in DEBUG builds — no license required. Try before you buy.
A license is required only for RELEASE builds on Android.
