Twitter revealed in March this year that it would be stopping its TweetDeck AIR, TweetDeck iPhone and TweetDeck Android service, however failed to give an exact date.
The Drum has learned from the TweetDeck blog that a date has now being given: 7 May 2013.
Twitter has said that the apps will be removed from all app stores and switched off, with Facebook integration of all TweetDeck products also ceasing to function.
Meanwhile, TweetDeck for Mac and PC will continue to function, but will be updated with the new Web and Chrome versions of the app.
Twitter said: "In many ways, doubling down on the TweetDeck web experience and discontinuing our app support is a reflection of where our TweetDeck power-users are going. Over the past few years, we’ve seen a steady trend towards people using TweetDeck on their computers and Twitter on their mobile devices. This trend coincides with an increased investment in Twitter for iPhone and Twitter for Android –– adding photo filters and other editing capabilities, revamping user profiles and enhancing search. That said, we know this applies to most of our users –– not all of them.
"And for those of you who are inconvenienced by this shift, our sincere apologies."
