Three moments

Where a race is won.

Most places are won or lost in the last minute before the start, on the first leg into the wind, and in what you change before next week. The app is built around those three.

Before the start

Mark both ends of the start line with a tap. The app tells you which end gives you a head start and by how much, how far you are from the line, and whether you are early or late for the horn.

Getting upwind

The angle that gets you upwind fastest, a tack or gybe call the moment you're off it, and a nudge the instant you've been lifted or headed.

After the race

Your race on a map. Each leg compared with the shortest route you could have sailed, each turn scored for how much speed it cost, and a trend over the season that shows whether it is getting better.

Two sailors

Built for your first regatta, and your fortieth.

New to racing

Start at the better end. The start line is almost never straight across the wind, so one end gives you a head start. The app points to it before the horn.
Cross the line on the horn. A countdown you can hear, and a number that says whether you are early or late.
Find your fastest angle. The app shows the angle that gets you to the mark quickest. Sailors call this VMG.
Tack when it pays. The app tracks wind shifts and tells you when you have been lifted or headed.
See what happened afterwards. Your race drawn on a map with every turn marked, and one plain sentence on what to try next time.

Experienced racer

See your start in numbers. Speed at the gun, distance to the line at the gun, and how much of your approach speed you carried across.
Stop overstanding. Every beat is measured against the shortest legal path at the angle you actually sailed.
Score every tack and gybe. Speed lost, time to rebuild, whether you pinched or over-turned.
Sail your true angles. Your polar against the class polar shows the angle you are slow at.
Settle it boat on boat. Share a race with the sailor you crossed and see who led at every moment.

Watch and phone

Race from the wrist. Mount the phone. Or both.

The watch is the instrument: countdown, distance to line, target heading, one glance each. The phone is the bigger screen, mounted on the boat as a full panel, or in a bag recording the track for later.

Questions

Before you download.

Does it work without a watch?

Yes. The phone has the full tactical panel and records every race. The watch adds the glance.

What happens if I stop paying?

Nothing is deleted. Your first five races stay open, the rest wait, and Pro reopens all of them.

Is it accurate enough to trust?

GPS is honest to a boat length or so. Everything derived from it is tested against real races, and the app tells you when it is guessing.
