Zoom is a software application that enables its users to do video calls and conferences via wifi with the additional option to only connect to the calls audio using the users cell plan. Furthermore zoom offers a premium service for calls with more than two participants lasting longer than 45min also enabling the user to record the call (video and audio). Each call has a chat where either public or private messages and files can be shared among the calls participants and is optionally moderated by a so called host who is usually the owner of the license or authorized by the license holder. Moreover the participants can engage in polls created by the host and react to the calls content by using a variety of emojis and signs that will show up in the users screen.
