GPX Workout is a handy iPhone app developed by Marcello Mascia that fills the gap in the native Apple Watch app when it comes to exporting workout data. With this app, you can easily export your running, cycling, and other workouts recorded on your Apple Watch into GPX files.

One of the standout features of GPX Workout is its seamless integration with HealthKit. The app can read data from HealthKit and convert it into GPX files, allowing you to have a convenient record of your workouts. Whether you want to analyze your data in your favorite GPX editor, upload it to Strava, or simply share it with others, GPX Workout makes it effortless.

Another great feature of GPX Workout is its iCloud Drive integration. If you have iCloud Drive enabled on your device, GPX files are automatically synced to a folder named "GPX Workout." This makes it easy to access and manage your workout files using the Finder app on your Mac or the Files app on iOS.

It's worth noting that GPX Workout is a one-man band project by Marcello Mascia. While the app is well-designed and functional, the developer welcomes comments and suggestions and promises to provide support to users.

Overall, GPX Workout is a valuable tool for Apple Watch users who want to export and share their workout data. With its intuitive interface and seamless integration with HealthKit and iCloud Drive, this app makes it effortless to manage and share your workout files.
