From Wooly Beast Software, LLC, developers of "Time Saving and Time Expending" applications and games for the iOS, comes Wooly Wind Chill, the Wind Chill Calculator.

Calculate wind chill temperature by simply selecting the air temperature and wind speed using the familiar "jog wheel". The calculated wind chill temperature is displayed "on the fly".

Temperatures may be displayed as either Celsius or Fahrenheit, and wind speeds as Miles Per Hour (mph), Kilometers Per Hour (kph), or for the nautical types, Knots (kn).

For those who travel by bike, motorcycle, boat, or other means where you find yourself exposed to the elements while in motion, calculate the approximate effective wind chill based your current moving speed (not factoring for actual wind speeds).

Best results are obtained on an iPhone with built in GPS support. Accuracy and reliability on other iOS devices lacking a GPS are not guaranteed.
