Opinions of some beta tester and users

Congratulations on the development of such a complete application, it offers a set of techniques, procedures, and analytical methods combined with the representation on maps that I have never seen. I was especially surprised by how easy and the little time that is needed in order to place on a map the results of the statistical analysis.
