Abstract
The comment\cite{kren17} claims that the paper Relativistic theory of the falling cube gravimeter \cite{ashby17} is incorrect. The authors of this comment assert that optical paths in the two interferometer arms of an absolute gravimeter shift only the absolute phase difference between interferometer arms and therefore cannot affect the measured value of the acceleration of gravity, and that the only needed relativistic correction is the commonly applied 'speed of light correction.' Neither claim stands up to scrutiny.Citation
