TweetDeck

X Pro (formerly known as TweetDeck) is a paid proprietary social media dashboard for management of X accounts. Originally an independent app, TweetDeck was subsequently acquired by Twitter, Inc. and integrated into Twitter's interface. It had long ranked as one of the most popular Twitter clients by percentage of tweets posted, alongside the official Twitter web client and the official apps for iPhone and Android.

Like other Twitter applications, it uses the Twitter API and permits users to send and receive tweets and to view profiles. On July 4, 2023, Twitter's Support account advised that in 30 days, users must be verified (and be subscribed to Premium) to use TweetDeck. TweetDeck was made unavailable to non-verified users by August 17, 2023.

It can be used as a web app. Until 2015 it could also be used as a Chrome app and until 2022 it could also be used as a macOS app. Users are now redirected to the web app.
