Hello, I'm Eike.

I build open-source tools.

activity_files

Five formats, one model. activity_files reads GPX, TCX, FIT, GeoJSON and CSV into the same structure, so your app handles every workout file the same way. Files from real devices are messy: activity_files never throws and explains every problem with a suggested fix. Edit, validate and convert in pure Dart or from the CLI. FIT is tested against real device files, not just the spec.
