Monitor real-time GPS coordinates with precision down to centimeters. Track location accuracy, speed, course direction, and altitude with live updates. View detailed location history with timestamps and export data for analysis. Set up custom geographic regions for entry and exit notifications. Monitor significant location changes and visit tracking for low-power location monitoring.
ADVANCED POSITIONING
Monitor compass heading with magnetic and true north readings. Track device motion with accelerometer, gyroscope, and magnetometer data. View location age and freshness indicators to understand data reliability.
IBEACON AND BLUETOOTH
Comprehensive iBeacon ranging to detect nearby Bluetooth beacons with signal strength analysis. Simulate iBeacon transmission to test beacon-based applications and location services. Discover nearby BLE devices and iBeacons with detailed signal analysis. Save and organize beacon configurations in a persistent library for easy reuse across ranging, discovery, and simulation features.
REGION MONITORING
Create circular geographic regions with customizable radius and notifications. Monitor region entry and exit events with detailed logging. Save and load region configurations from a persistent library. View region events history with timestamps and export capabilities. Visual map display of monitored regions and current location.
PROFESSIONAL DIAGNOSTICS
Detailed system capability analysis showing available location services and authorization status. Background location monitoring with comprehensive logging. Location permission analysis and troubleshooting guidance.
DEVELOPER TOOLS
Real-time location service status monitoring. Detailed error reporting and debugging information. Custom UUID generation for iBeacon applications. Comprehensive location settings validation and recommendations.
USER INTERFACE
Clean, intuitive design optimized for both portrait and landscape orientations. Real-time data updates with customizable refresh rates. Dark mode support for comfortable viewing in all lighting conditions. Comprehensive search and filtering across all features. Export and share functionality for collaboration and reporting.
DATA MANAGEMENT

Latest updates
1.4.2
This update is all about privacy, battery life, and reliability.
• Stronger privacy protections — Your location history, saved regions, and beacon library are now stored with full device encryption and are excluded from backups. The home screen widget now uses approximate coordinates (~100 m) instead of your exact position.
• Better battery life — Location history is now saved in efficient batches instead of on every GPS fix, and the widget refreshes more intelligently, reducing background disk and power usage during long tracking sessions.
• More reliable GPS readings — NavDiags now automatically rejects invalid fixes (out-of-range coordinates, stale or future timestamps) so your diagnostics reflect real data.
• Beacon improvements — Beacon configurations are validated before broadcasting begins, preventing invalid setups.
• Updated privacy policy — Now clearly explains the two Apple services the app talks to (weather and address lookup) and confirms that nothing else ever leaves your device.
• Plus a significant under-the-hood cleanup for a smaller, faster app.
