EIS Spectrum Analyzer is free of pay for commercial use, which is of course an advantage. It works fairly good for simple impedance spectra, but with our non-trivial case it could not result in anything satisfactory:

Another serious drawback of EIS Spectral Analyser is that it is absolutely impossible to save plots as image files. What you see above this, is just a series of screenshots (Myquist + Bode Modulus + Bode Angle, each of them separately). On the other hand, you can save a fitted spectrum as an ASCII file and use it in Excel, Kaleidagraph or another application for building a plot according to your needs and preferences.
