Update: Wind Meter has been in the top 20 paid apps in the weather category on iTunes for 24 months straight. Thanks! We couldn't have done it without you!
Wind Meter - use your iPhone to estimate the speed of the wind. Wind Meter works by measuring the volume of the wind on your iPhone microphone and converts it into a wind speed reading.
To use, simply point the microphone into the wind and push Get Wind! Wait a few seconds and push Got Wind! The final reading is the average of the period. (The application is upside-down so you can read the meter while pointing the microphone into the wind.)
Wind Meter supports multiple units of measure including Miles Per Hour, Knots, Kilometers Per Hour, Beaufort, Feet Per Second, and Meters Per Second.
Use Wind Meter to estimate the wind velocity for a variety of recreational uses.
Note: This application is not meant to take the place of scientific instrumentation and is for recreational use only.
Supports 3G, 3Gs, 4G, and 4Gs iPhones
