This article explains how to live stream on X (formerly Twitter) using the iOS and Android versions of the app.
How to Stream on X (formerly Twitter)
You can start a live broadcast from the official X app for iOS and Android devices. A cellular or Wi-Fi signal is required, and your account must be public. If your Twitter account is set to secure, you will not be able to live stream.
Your followers and the general public will be able to watch your broadcast as it happens and later via an on-demand video. Similar to livestreaming on Instagram, X users can interact with livestreams by typing a message in the chat or using a heart emoji.
Open the X app on your iOS or Android device and select Compose in the bottom left corner. This icon is either a plus sign or a pen.
