From the developer:
GeoKalk is a calculator for vectors (lines and planes) and tensors (strain and stress). Multiple calculators can be opened, edited, and saved. The entries and the results are presented in tables, as well as in a stereonet and a Mohr circle. In 3D stress, the stereonet and the Mohr circle can be colored by slip tendency. The entries can be read from text files. The results can be exported as text and plots.
