Twitter has been spotted working on making TweetDeck a premium feature through its Twitter Blue subscription service. According to reverse app engineer Jane Manchun Wong, who searches the code of mobile apps to spot features and upcoming changes in development, the social media giant is currently working on the addition to Twitter’s premium offering, adding it to the Twitter Blue feature list within its Android app.

Wong recently found Twitter working on adding a reference to TweetDeck in the list of Twitter Blue features in the company’s Android app. Last week, Wong came across code in the app that would restrict access to TweetDeck to users who have a Twitter Blue subscription and redirect those who don’t to sign up for one.
