OGK Inspector

Am-241 spectrum view
FWHM measurement	LogScale view

OGK Inspector is the official Android companion app for OpenGammaKit spectrometers, designed to interface with supported hardware via USB serial (compatible with Android 7.0+). Built for high-precision diagnostics and calibration workflows, it now includes advanced signal processing tools such as Savitzky-Golay filtering and wavelet-based peak detection.
