As summer arrives, the temperature rises. Heat Index is a simple application that lets the user enter the air temperature and the relative humidity. Press a button and the application will calculate the heat index temperature. Temperature can be entered in Fahrenheit or Celsius.

No graphics to take up memory, just simple data entry and a quick calculation.

Heat Index Lite is ad supported. If you want an ad-free version, enter Heat Index in the iTunes search window to find the paid version.
