Keep your Twitter relevant to your interests.
Not interested in someone’s account anymore? Accidentally followed someone and want to undo it? Unfollow with the tap of a button to stop seeing their Tweets in your timeline.
Use the same process for unfollowing accounts as you do for following by tapping the Follow button in a Tweet, next to an account name, or from a profile page.
Stay on top of the Tweets you see.
If you’re no longer interested in seeing Tweets related to a Topic, you can unfollow--just like you would unfollow an account.
From your profile, tap the Following button next to the Topic in your Topic list.
