I've used the program at DOF Master's site
to get the chart for hyperdistance calculation into my Palm Pre. The downloadable program allows you to set focal lengths and f/stops, then using the chart you get the hyperlength distance. This is not an app as with the iphone where you have to stop and plug numbers into, just a quick glance chart with immediate answers.
I downloaded the program to my computer. I have Adobe Acrobat on my computer. I set the min and max focal lengths at the bottom of the graph, then set the f/stops to the ones I use.
When I produced the charts I wanted, I "printed" them using Adobe as a .pdf to my desktop. I emailed them to myself and saved the charts in the PDF file on the phone. You can do this with any smartphone that has PDF document storage.
