Pumpfoil

Track Every Pump

Turn your sports watch into a pumpfoil computer: GPS track, foiling distance, pump frequency and glide phases – fully automatic, from every session.

Right on Your Watch & Phone
Apps for Garmin, Apple Watch, iOS, Wear OS, Android and Polar and Suunto API integration (COROS, & Amazfit coming soon – as of July 2026).

What you get:

* Configurable data fields: speed, heart rate, distance, time
* On-foil vibration alert when you go above or below your target speed (calculated from foil & weight)
* Recording runs locally & offline – syncs automatically
