Abstract

Winter et al.’s recent investigation, “A Comparison of Self-Reported COVID-19 Symptoms Between Android and iOS CoronaCheck App Users,” reveals differences in the demographics and COVID-19 symptoms reported by users of Android and iOS systems. These findings not only provide more information about the varied experiences of individuals during the COVID-19 pandemic but also suggest that conclusions reached in studies using one operating platform may not be generalizable to users of other platforms.
