Race Sail Tracker.
The idea was to create All-in-one app for the sail racers. Hope you'd like it.

"Race Sail Tracker application provides relevant information for race training or competing sailors: a race start sequence, Velocity Made Good, Degrees Off the Wind, actual / maximum speed and additionally manual correction of the wind direction. It works offline without a smartphone as well (appreciated for sailors being abroad). Sailors don’t need a separate start sequence watch anymore. Polish top kite-racers were involved in development".
