    Overview<\/h2>\n\n\n\n

    AIR\u00b3 Vario Watch turns a Wear OS smartwatch into an acoustic variometer. It reads the watch’s barometric pressure sensor many times per second, derives your vertical speed from it, and plays a tone whose pitch and rhythm follow that vertical speed \u2014 the sound free flight pilots use to find and centre thermals without looking at an instrument.<\/p>\n\n\n\n

    That is the core, and it is what you will use it for most. But a variometer on its own has not been a complete flight instrument for a long time, and this one does not stop there. While you fly, the watch also:<\/p>\n\n\n\n
