Merge GPX vs TrailFix

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.
