By a pilot, for pilots.
WindXplorer is built by Adrien de Sade, competition pilot, 2018 French Champion and member of the French national hot air balloon team.
The app was born from a pilot's need: to decide quickly and well, with the right tools, before, during and after the flight.
Already more than 100 pilots in the beta and 350 flights logged.
