This unique feature, inspired by a fellow bicycle commuter friend, utilizes the GPS on the iPhone 3G/3GS to determine you current moving speed, and uses this to calculate the wind chill based on the selected air temperature.

This feature is for anyone who travels at any sort of speed in or on an open vehicle, such as a bicycle, motorcycle, boat, snowmobile, etc.

While this feature can be accessed on an iPod touch, readings will be inaccurate. Ambient wind speed is not factored into the results.
