GPX - KML - OpenTrackEditor

OpenTrackEditor is a powerful, open-source Android GPS editor for GPX and KML files. Edit individual waypoints, create or join tracks, split or reverse segments, and convert between GPX and KML formats. The app is optimized to handle very large files (millions of waypoints) and provides filters to simplify and decimate tracks, plus export options with custom file names. Its clean, intuitive interface makes route planning and post-activity cleanup quick and precise on your phone or tablet.

Privacy-first and community-driven, OpenTrackEditor is GPL-3.0 licensed with no ads, no tracking, and no data collection. Upcoming features include elevation graphs, advanced filters (Douglas–Peucker, Kalman), noise removal, EXIF/timestamp editing, custom map layers, and in-app statistics.
