Wind Chill Factor Calculator


Available in the App Store

* Featured by Apple in ‘What’s Hot’ in the United States under iPad > Weather

The Wind Chill Index Factor displays automatic weather calculation based on iPhone/iPad localization features with available internet access. Just press the Fetch button.

This is a tool for measuring the perceived when outside by measuring the impact of wind on the temperature of the air. The wind chill factor can not lower a temperature below the current air temperature, but instead it speeds up the decrease in temperature proportional the speed of the wind

Both the Old model for calculating the Wind Chill Factor, pre-2001 formula, and the New Wind Chill Index devised by the National Weather Service in 2001 are used. The values are calculated to the second decimal place for extra accuracy.

Inputs for Air Temperature can be given as Fahrenheit or Celsius. Acceptable inputs for wind velocity are Knots, Miles per Hour, and Kilometers per Hour.

This app features:

• Send your calculations or conversion by email
• Universal App (iPhone, iPod Touch, and iPad)
• Retina Display graphics
• Fast app switching
• Automatically Saves Your Inputs

Note: Windchill Temperature is only defined for temperatures at or below 50 degrees F and wind speeds above 3 mph.

Heat Index & Heat Category

Available in the App Store

• Featured by Apple App Store in Weather > What’s Hot for the iPad in 108 countries.

The Heat Index & Heat Category is the Universal App for measuring the perceived temperature.

Because the body normally cools itself by perspiration, when relative humidity is high, the evaporation rate is reduced, and heat is removed from the body at a lower rate causing it to retain more heat than it would in dry air.

This calculator takes into consideration not just the air temperature, but also the relative humidity, giving a good estimate of the perceived temperature when the the air temperature and relative humidity are entered. The heat category is a measurement taken from NOAA’s National Weather Service Heat Index Chart and is used to assist in determining how much caution should be exercised when outdoors for any period of time.

The results can also be emailed through the iPhone / iPod Touch / iPad’s email application using a prewritten template.

The answer is computed for both Fahrenheit and Celsius for convenience.

The calculator is the most effective when the temperature is at least 80 °F / 26 °C and the relative humidity is at least 40%.

This app features:

• Send your calculations or conversions by email
• Universal App (iPhone, iPod Touch, and iPad)
• iOS 5 & 6 are supported
• iPhone 5’s 4 inch screen and the original 3.5 inch screen are supported
• Retina Display graphics
• Fast app switching
• Automatically Saves Your Inputs

Press the FETCH button to get your location calculated HEAT INDEX for the iPhone, iPad, and iPod Touch. Then try calculating your “What if’s” by changing the values.

Marine CFT Score Calculator

Available in the App Store

The Marine CFT Score app is a tool for calculating the pass or fail status of the Combat Fitness Test as well as the score for each individual event. A corresponding status for each event criteria, MTC (Movement to Contact), AL (Ammunition Lift), and MANUF (Maneuver Under Fire) is computed individually for score and pass or fail status. The individual events are then compiled to calculate the overall score, classification (first / second / third), and the Composite Score.

Calculations take into account scoring differences for altitudes above 4500 feet for both male and female marines.

Simply punch in your raw numbers and your scores will automatically update. It is as simple as that.

All calculations are computed based on USMC MCO P6100.13 with Chapter 1.

The results can also be emailed through This app features:

• Send your calculations or conversions by email
• Universal App (iPhone, iPod Touch, and iPad)
• Retina Display graphics
• Fast app switching
• Automatically Saves Your Inputs

No network connectivity required.
