Good news, Now sailors have another tempting application to bring out the best from their favorite high-tech gadget. Your iPhone now can become a windspeed instrument as well! Some very clever engineer types realized that the intensity of wind blowing into the microphone of an iPhone (that roaring static we hear when people call us from their boats) could be calibrated to reveal the speed of said wind.
The harder the blow, the more intense the sound—and the higher the wind gauge needle moves. How cool is that! According to reviews, it really works.
