FoilMotion is a sophisticated outdoors tracking application tailored for a range of hydrofoiling water sports. It offers enhanced accuracy for sports such as wingfoiling, kitefoiling, surfing, downwind paddling, and pumpfoiling, addressing the specific tracking challenges these sports present.
“Finding the pump movement in the sensor’s data – Foilmotion” video is a technical deep dive into the development and data analysis behind the FoilMotion app. The video features a conversation between the app’s creators, Sascha and Jörg, as they discuss the journey of building a specialized tracking tool for foiling (a hydrofoil-based water sport). They focus specifically on the engineering challenge of identifying “pump movements”—the rhythmic motion riders use to maintain flight—within raw sensor data to provide better performance analytics for users.
Key Highlights and Takeaways
- App Development Journey: Sascha shares the personal and professional risks involved in leaving a stable job to pursue his passion for developing a dedicated foiling tracker.
- The “Pump” Challenge: A significant portion of the video is dedicated to the technical logic required to distinguish a rider’s “pumping” action from other movements using motion sensors.
- Data Analysis: The creators explain how the app collects and interprets data to help foilers track their progress, refine their technique, and understand their sessions beyond simple GPS tracking.
- Business Strategy: Jörg provides insights into their approach to user engagement and how they plan to grow the community around the app.
- Future Features: The discussion touches on upcoming capabilities for the app, aiming to make it the most in-depth tool for wing foiling and pump foiling enthusiasts.
FoilMotion has evolved significantly, transitioning from a niche development project into a fully-fledged tracking ecosystem for multiple water sports.
The app is primarily designed for the Apple Watch and Garmin ecosystems, focusing on high-definition motion tracking that standard GPS apps often miss.
How to Download FoilMotion
The app is available across several platforms depending on your hardware:
- iOS & Apple Watch: Search for “Foil, Wing, Surf – FoilMotion” in the Apple App Store. It requires iOS 17.0+ and watchOS 10.0+.
- Garmin Watches: You can find the “FoilMotion” data field or app in the Garmin Connect IQ Store.
- Android: While there isn’t a standalone tracking app for Android yet, an iPhone companion app is used for detailed data analysis of sessions recorded on your watch.
Tracking Accuracy & User Reviews
Based on current user feedback and technical specifications, the app is highly regarded for its precision:
- Motion vs. GPS: Users highlight that the app doesn’t just rely on GPS (which can be “jumpy” on water). It uses the watch’s accelerometer and gyroscope to interpolate data, resulting in much smoother and more accurate tracks during sharp turns.
- Max Speed Accuracy: A popular recent update changed max speed calculation to a 5-second window rather than a single (often erroneous) GPS point, which users find far more reliable for comparing performance.
- Pump Detection: Reviewers confirm the “pump counting” algorithm discussed in the video is effective, specifically praising the Automatic Dockstart Detection which separates actual foiling time from standing on the dock.
- Community Consensus: It currently holds a 4.8/5 rating on the App Store. Some users have noted the subscription price ($3.99/mo) is a bit high for casual users, but they admit the technical depth—like G-force analysis and VMG (Velocity Made Good)—is unmatched for serious foilers.
Unique Features for Enthusiasts
- Session Story: A replay feature that lets you “scrub” through your session on a map to see exactly where you were pumping versus gliding.
- Maneuver Detection: Automatically identifies and grades your jibes, tacks, and 360s.
- Export Capabilities: Supports GPX export so you can move your data into other platforms like Strava or specialized analysis software.
The following Garmin devices are compatible with the FoilMotion app via the Connect IQ Store:
Premium & Outdoor Series

💡Key Technical Requirements
- Sensors: While older watches (like fēnix 6) may appear in some “general” water sport lists, FoilMotion specifically requires watches with high-fidelity motion sensors to count pumps accurately.
- Recording Interval: For the best results, it is highly recommended to go into your watch settings and set Data Recording to “Every Second” instead of “Smart” recording. This ensures the app doesn’t miss the quick oscillations of a pump-foil session.
- Companion App: Even if you use a Garmin watch, you can still use the FoilMotion iPhone Companion App (iOS 17.0+) to sync your Garmin sessions and view the “Session Story” and 3D map replays.
