Merge GPX

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.
