TweetDeck for iPhone.
As reported in early March, Twitter will be killing off TweetDeck for Apple's iOS, Google's Android and Adobe's AIR mobile platforms, as well as Facebook assets, in the coming weeks, and according to an announcement on the company's blog, the discontinuation will take place on May 7.
Previously, the microblogging giant didn't put a specific date to the shutdown, saying to expect the move in "early May."
Twitter will be focusing on web-only development for TweetDeck, and expects to keep the dedicated Web and Google Chrome apps versions alive. In addition, desktop versions of the app will still be available to Mac and PC users and should receive regular updates.
Twitter purchased the real-time conversation tracking app in 2011 for $40 million and has since groomed it into a powerful web app.
