FireAway for

From Christopher G. Brand:

FireAway provides time saving features such as computing RH and dewpoint from dry/wet bulb readings and computing fine dead ful moisture (no more fumbling with tables!), and very sophisticated surface fire modeling to predict fire spread and intensity. Until now, most firefighters in the field did not bother obtaining this information because it was impossible or impractical. Now you can do it in seconds and be better infomed and more safe.
