On Twitter for iOS and Android, when someone you follow starts or speaks in a Space, it’ll appear at the top of your timeline as a purple bubble for as long as it’s live. When you join a Space as a listener, you can react to what you hear with emojis, check out any pinned Tweets, follow along with captions, Tweet or DM the Space, or request to speak.

When you join a Space as a speaker, in addition to talking, you can pin Tweets to the Space, turn on captions so everyone can follow along with what you’re saying, and Tweet the Space so your followers can join.
