Lu,
Celestial is also available for Android. Other similar Android apps are StarStruck Navigation ($2.99) and Marine Celestial Navigator (free?). StarStruck does not do a plot, but puts your most likely location on a map.chart. Marine Celestial Navigator does not plot.
For the PC, there are several that plot. The ones that come to mind are Teacup Celestial (free), Omar Reis' Navigtor Light, ASNAv, Jim Bonner's NavTools, NavSoft's AstroNav, and NavAstro.
FWIW, there is something confusing about Celestial. If you enter an IE, IC is shown with the same sign, although the calculation is done properly. I have reported this to the developer, who has not yet responded (but has been good about responding in the past).

I should have mentioned that I have seen a very nice iPad app "Celestial by Navimatics" that seems very complete and produces LOP plots. It is claimed that it works for iPhone, too, but that may be squeezing too much into a 3" screen. And $19.99, which is less than 1/6 of the price of Starpilot.

Lu, Starpilot does, but it's not free. There is a version for iPhone.Hewitt

There are several programs out there that do sight reductions, ranging from a free app I have on my iPhone that does just the Law of Cosines reduction, you have to supply LHA and Dec to Stan K's quite nice Celestial Tools program for the PC.
But ... all these end with intercept and azmuth. Is there a program out there (preferably free/shareware) that will go all the way to offering some sort of plot of one's DR position and the LOP resulting from the sight?
