RelaxIS is a stand-alone impedance analysis software.
It offers extensive capabilities in handling impedance data, plotting it in various different representations (Nyquist, Bode, custom) and transfer functions and fitting the spectra to equivalent circuits or physical models (including Autofitting capability).
RelaxIS also allows further evaluation of the fit results, e.g. creating custom plots of fit results vs. metadata (e.g. temperature) or by performing built-in Arrhenius- and VFT fits.
The included Circuit Simulator is also extremely helpful in teaching impedance spectroscopy by giving the ability to free define, plot and change simulated data of equivalent circuits or other models.
RelaxIS is available with two license models. Both licenses are floating licenses, that allow the installation on an unlimited number of machines, with simultaneous use on 1 machine per license.
- One-time purchase, permanent license for the current major version (RelaxIS 3)
- Purchase of a time-limited license (i.e. 12 month) without automatic renewal
Both models include updates for the current major version (RelaxIS 3
"With RelaxIS I can fit my impedance spectra and extract conductivity values within minutes; instead of hours which was the case with another fitting software."
Dr. T. Goulas, Loughborough University
"RelaxIS has been invaluable."

"Moving forward this is the only software I would want to use."
R. Faase, Modern Electron, Inc.
"RelaxIS is a rich software suite that combines many tools used for the evaluation of spectra measured in impedance spectroscopy experiments."
"Once you have used RelaxIS, everything else is always a downgrade."
Dr. S. P. Emge, Cambridge University, UK
