We review matter wave and clock comparison tests of the gravitational redshift. To elucidate their relationship to tests of the universality of free fall (UFF), we define scenarios wherein redshift violations are coupled to ("type II"), or independent of ("type III"), violations of UFF, respectively. Clock comparisons and atom interferometers are sensitive to similar effects in both scenarios.
