Designed for private pilots and sailors, this clever app and add-on turn almost any smartphone into a wind speed and direction tracker.
Sporty's Pilot Shop describes it as a "high tech meteorological tool," but that might be hyping it a bit. We thought it might have application as a field gauge for wind power enthusiasts. Check the average wind speed on a nearby hill. Do a real time test on your turbine's performance at various wind speeds.
It works like this: "Simply download the free Vaavud app and plug the wind meter into your ear phone jack. The app gives you a clear overview of average, actual and maximum wind speed, as well as a real time graph. The highly sensitive built-in sensor allows it to drive both wind speed and direction. The unit of measure can be changed on the fly by simply tapping the screen. (Available units: m/s, Kmh, mph, Kts and Bft.)"
You can purchase the windmeter directly from Amazon for about $60. It works with iPhones 4 and later, iPads and most Androids. Order from either of the two options below.
