  The COVID-19 problem has not gone away with the passing of the seasons. Even
though most countries have achieved remarkable results in fighting against
epidemic diseases and preventing and controlling viruses, the general public is
still far from understanding the new crown virus and lacks imagination on its
transmission law. In this paper, we propose MeetDurian: a cross-platform mobile
application that exploits a location-based game to improve users' hygiene
habits and reduce virus dispersal. We present its main features, its
architecture, and its core technologies. Finally, we report a set of
experiments that prove the acceptability and usability of MeetDurian. An
illustrative demo of the mobile app features is shown in the following video:
