For Sailors

Record a GPS track, speed, heel, compass heading, and optional video on the water — Free tracking, or Sail & Race to auto-build a course and race others nearby. Works fully offline; upload once you're back in range.

Send a session for analysis from sailingmetrics.com or the app — supported formats (GPX, FIT, KML, VKX, GLV, video), boat and wind, and what happens as it processes into an activity.

A tour of an activity's analysis page — the map/video/controls player, drawing a course, and the Session Overview, Leg by Leg, Start, Speed Analysis, and Maneuvers tabs.

Load GPS tracks from multiple sailors onto the same map, define gates and marks, and automatically split each track into legs. Compare duration, distance, speed, and VMG side by side.

Live-coached practice sessions (Pro feature). The app speaks short pieces of commentary as things happen on the water — legs, tacks and gybes, mark roundings, wind shifts, and race starts — compared against your own performance earlier in the session.

A real-time dashboard showing VMG, SOG, COG, heel angle, and heading simultaneously. Metrics are averaged over a configurable period and can be read aloud so you can keep your eyes on the water.
