The \beta decay of the proton-rich nuclei 94Ag and 100In was investigated at the GSI on-line mass separator by using different arrays of Ge and Si detectors, as well as a total absorption spectrometer (TAS). The preliminary analysis of the \beta \gamma \gamma coincidences in case of 94Ag confirms the existence of all \gamma rays observed in a previous measurement and forms the basis for an improved decay scheme. In the case of 100In, the population of states up to the 8+ yrast state in 100Cd has been identified from \beta \gamma \gamma coincidences. The experimental \beta feeding measured in the TAS is compared to predictions of large-scale shell-model calculations, which favour a spin and parity of 6+ for the 100In ground state.
