Many programs have X hairs or similar or a graph that can be used. What K3 has over the majority is that it will give you a numerical readout of what your drift is in arcsec/min. Once you get that to 0 (or close) in both Alt and Az you know you are polar aligned, you don't have to wait for graphs to move or stars to move off cross hairs.
Phd does have the cross hairs and a graph but I'm not sure if the graph can be used if you are not guiding.
