Gustly
GPS Windsurf Session Tracker
Free · Designed for iPad. Not verified for macOS.
Gustly is a GPS session tracker for windsurfing, kitesurfing, windfoiling, and wingfoiling.
Record on your phone or Apple Watch, import sessions from compatible GPS devices, and turn your tracks into useful performance insights.
Session Analysis connects your results to the water. Select a speed run to see when it happened on the timeline and where it happened on the route. Scrub the chart and zoom in on the map to explore your session in detail.
With Gustly you can:
- Record GPS sessions on your phone or Apple Watch
- Keep recording an active phone session when the screen is off
- Import GPX and FIT files, including Garmin exports
- Review 2-second speed, top 10-second runs, distance runs, Alpha 500, endurance results, and available gybe and tack insights
- Browse your session history, routes, and totals
- Save sessions locally and sync when you’re back online
- Export your session data
- Use iPad’s larger screen to explore maps, timelines, and results
Location access is used to record active GPS sessions. With your permission, Health access supports Apple Watch heart-rate data and workout saving.
Gustly is a performance-tracking tool, not a navigation or safety device.
