Flash2Bang iPhone app

Designed for military personnel out in the field, Flash2Bang is an app for the iPhone and iPod Touch used to calculate distance based on an observed event and the following sound associated with that event. Since the speed of sound is affected by air temperature, it includes a temperature control that can also serve as a Fahrenheit/Celsius converter.

This app was covered in the April 5th, 2009 print edition of Army Times. In the “Off Duty” section, the article titled “Appsolutely” written by Jon R. Anderson covers numerous applications for mobile devices useful to military personnel, broken out by categories such as “Stay Connected”, “Fitness” and “Downrange”. Flash2Bang was listed as one of four applications under the category “In The Field”.

“Whether you’re trying to calculate the distance from your position to an enemy mortar team or an approaching thunderstorm, Flash2Bang has got you covered. This simple tool does a simple job well – press start when you see the flash, press stop when you hear the bang. Toggle for instant meter/yard conversion. Punch in the temp for greater accuracy.”
