This Streamlit app fits potentiodynamic polarization data using Butler-Volmer and BV + film growth/dissolution models. It supports Gamry .DTA files, signed current .csv and .xlsx files, and one-step or two-step absolute-current Excel formats.

The app reports key corrosion parameters including Ecorr, Icorr, current density, anodic and cathodic Tafel slopes, Stern-Geary B, polarization resistance Rp, goodness-of-fit metrics, and an LPR cross-check.
