[iPhone God App] It was found using the Wildland Toolkit actually

Wildland Toolkit is a calculator and reference guide for wildland firefighters. With it, you can predict fire behavior much like a weather prediction. Just enter the fuel, weather, and topography information and Wildland Toolkit will generate:

--RH and Dewpoint
--Fine Dead Fuel Moisture
--Probability of Ignition
--Flamelength
--Rate of Spread
--Scorch height
--Direction of Max Spread
--Effective Windspeed

All 54 of the new fuel models are supported, with a guide to select the proper fuel model, complete with sample photos.

NOTE: There are no known calculation errors in this version. We will immediately fix any problems reported to us directly.

Wildland Toolkit is not a tutorial on wildland fire behavior, so if the terms above do not make any sense, then this application will not teach you. It is assumed that you know the same background information that is presented in an S290 or S390 class. The calculations done in the Wildland Toolkit are similar to what is done with the BEHAVE software, but you will find the user interface much easier to use.

In addition, numerous safety checklists and reference guides are included, such as watchouts, fire orders, safety zones, structure defense, etc. Photos and diagrams are provided for cloud types, hand signals, common wildland tools, and ICS org charts. An interactive practice quiz is included for NIMS IS-700 and S290.

Now a universal app, so one purchase gets you iphone, ipod touch, and iPad support.
