From the developer:
TrackGuide GPX Editor is a free companion application to TrackGuide for iOS. It lets you edit, import, modify or create guided Walks that you can export as GPX files or share with TrackGuide on iOS/Apple Watch. The app allows you to import GPX files, move, add or remove points, add interesting points with multi-lingual descriptions and pictures, and import Walks saved in iCloud by TrackGuide iOS.
