Merge GPX: Powerful iOS Native Route Merging!

"Merge GPX" routes with ease. Perfect for combining multi-day recordings, reconnecting interrupted journeys, integrating data from multiple devices, and creating comprehensive route visualizations. Quickly handle multiple files from different sources, and enjoy seamless integration with Apple Files; all offline with a beautiful UI. Your adventures, your way, right on your device.


With merged routes you can:
- Combine multiple GPX files recorded on different days or devices to create one continuous route for complete journey visualization
- Reconnect interrupted recordings when GPS devices fail mid-activity (gaps in data will be filled)
- Integrate data from multiple sources
- Create single navigation files for complex multi-segment journeys (no more switching between different "courses" on your Garmin during rides)
- Build complete trail networks by combining individual segment recordings into comprehensive area maps


The app also includes:
* Support for all types of .gpx files from any GPS device or app
* Very small app size (smaller than some web pages!) (for easy downloading on mobile data connections)!
* Intelligent route connection using geodesic paths to bridge gaps between segments
* Preserves recorded time, elevation, cadence and heart rate data (if present)
* Native Dark mode support
* Merge options:
- Automatically sorted on import based on nearby start/endpoints.
- Manual arrangement (drag and drop segments in your preferred order)
* Two map view options:
- 3D Earth view for terrain visualization
- Traditional Map view for detailed route planning
* Share merged routes with friends or sync directly to navigation devices via the Files app
* Data validation to ensure clean, continuous merged tracks
* Optimized to fully utilize devices running iOS 18+


Transform fragmented GPS data into complete journey stories - whether you're documenting epic adventures, creating navigation-ready routes, or building comprehensive activity records from multiple recording sources.
