App Store Description

The first "Heat Index" tool that uses the Lans P. Rothfusz equation.

The heat index (HI) is an index that combines air temperature and relative humidity, in shaded areas, that is the feeling of "hot" or "cold" that is felt; it is due not only to the air temperature, but also to other environmental conditions, such as humidity and wind.

The heat index was developed in 1979 by Robert G. Steadman.
The computation of the heat index is a refinement of a result obtained by multiple regression analysis carried out by Lans P. Rothfusz and described in a 1990 National Weather Service (NWS) Technical Attachment (SR 90-23).

The heat index is also known as the "felt air temperature", "apparent temperature", "real feel" or "feels like".
The humidity in the air can increase the sensation of heat, while the wind can increase the sensation of cold.
For example, when the temperature is 32°C (90°F) with 70% relative humidity, the heat index is 41°C (106°F).
