Twitter has announced today TweetDeck for iPhone (and Android/AIR versions) will be discontinued in early May to concentrate development on modern, web-based versions of TweetDeck:
To continue to offer a great product that addresses your unique needs, we’re going to focus our development efforts on our modern, web-based versions of TweetDeck. To that end, we are discontinuing support for our older apps: TweetDeck AIR, TweetDeck for Android and TweetDeck for iPhone. They will be removed from their respective app stores in early May and will stop functioning shortly thereafter. We’ll also discontinue support for our Facebook integration.
Existing users of TweetDeck for iOS probably saw the writing on the wall, considering the most recent update came 16 months ago, an unacceptable timeframe for updates since the app was owned by Twitter. In other words, the app died when it was purchased by Twitter.
Additionally, v1.0 of Twitter’s API which TweetDeck for iPhone relies on will be retired, so existing users should probably GTFO and find a new Twitter client to avoid any downtime (is anyone still using TweetDeck?).
Update: Within the announcement Twitter noted Mac and PC apps will continue to get new features:
We think these web and Chrome apps provide the best TweetDeck experience yet, and that they are the apps in which you’ll want to see us add new capabilities first, followed closely by our Mac and PC apps.
