  • Example workout recorded on 29 September 2026 with the iOS app. Oar, GPS and boat motion come from the matching recording files.
  • The phone was used as the boat-motion source. Boat speed combines GPS with phone motion; GPS pace and distance describe travel over ground.
  • Moment, work and power use the force factor saved with this recording. Adjustments in this example affect only your open copy.
  • Choose Core or Advanced, then select curves or metrics under Oar, GPS, Time, Boat or Body. Values without supported data remain unavailable.
  • Save a Setup to reuse your plot selections, scales, map view and animation view with another report.

Motion curves and GPS Stroke oscillation, set, pitch and track

Speed and distance checks describe full-cycle IMU-only relative boat motion, without GPS. The V² energy-loss check uses fused speed to measure modelled excess squared speed. Set, pitch and turn are reported in degrees.

Interpretation and confidence
  • Boat motion is measured from the phone. Relative speed and distance show changes within each stroke; fused speed includes GPS ground speed.
