While meetings can be started and scheduled from the Zoom web portal, you can also schedule/start meetings directly from the Zoom application. It is also important to access the Zoom application to set certain in-app settings, including Virtual Background, Audio/Video settings, as well as other options.
Note: The Zoom Desktop Client and Mobile App have different features than the Zoom web portal. The Zoom web portal is primarily used for changing your meeting settings and Zoom Phone settings. You can also use the web portal to customize your profile.
