Systems with both spin and phonon degrees of freedom are ubiquitous in physical fields ranging from condensed matter to biophysics. However, methods to compute the dynamics of such systems are scarce, especially in high dimensions. In this work, we combine the Truncated Wigner Approximation (TWA) for bosons with its recently developed discrete version (dTWA) for spins to describe the dynamics of coupled spin-phonon systems. We benchmark the method by comparing to exact results and discuss applications to trapped-ion and cavity experiments.
