Depth of field calc for Win Mobile

Does anyone know if a good depth of field calculator that will run on Windows Mobile 6 or Excel that take into account your cameras crop factor? I can find tons of apps and Excel files but seem to come up empty trying to locate an app that considers crop factor in the calculations.

thanks

I use this one:

The Help File tells you how to set the "resolution" setting to match your camera's sensor size/resolution, which I understand to account for crop factor.

For not too a large distance you can use any FF calculator for a given focal length, f-number, and distance and then divide, yes, divide, the result by the crop factor. Usually it's a pretty good approximation in a pinch. You might use the http://www.dofmaster.com/dofjs.html to play.
An example - you have a 85 mm lens at f/5.6 and the object at 20 feet.
The DOF for a FF camera is 5.76 feet
The DOF for 40D (x1.6 camera) is 3.61 feet.
The ratio is 1.6
