You can join a meeting via the desktop, mobile or web app.
The application, which is available for Linux, macOS and Windows, can be downloaded automatically from the Zoom website.
Apps are available for iOS and iPadOS in the App Store and for Android in the Play Store.
You can also join meetings using Zoom's recommended web browsers Google Chrome, Mozilla Firefox or Microsoft Edge.
