iPhone Wind Meter App.
By measuring the windnoise in the microphone goingApps has come up with this rad little application that'll turn your iPhone into an anemometer. Hows about that for a wicked idea!
Here's what goingApps has to say:
The first application to let you measure the wind speed using your iPhone. Know the approximate wind speed between 0 and 28 mph wherever you go!
To use, press the start button. Wait a few seconds. Press stop. The final reading is the average of the period between stop and start, giving you the approximate average wind speed. Point the microphone at the bottom of the iPhone directly into the wind.
Easily convert between mph, kmh, knots, fps, m/s, and Beaufort.
This application uses sound conversion to gauge wind velocity. As the wind speed increases, the application converts the louder noise on the microphone into a wind velocity reading.
Derive approximate wind velocity for a multitude of recreational uses such as windsurfing, sailing, kitesurfing, golfing, hunting, kite flying, etc.
