TweetDeck was once a successful Twitter client which ran almost everywhere, but then Twitter bought it, and the stand-alone apps have gradually been killed off in favour of the web client.
Tweeten is a new client which aims to bring the TweetDeck experience back to your system, via clients for Windows, OS X, Chrome and Edge.
The Chrome edition removes some of the old TweetDeck interface clutter, while also applying lots of visual tweaks and design changes (the developer's main aim is to "make TweetDeck prettier").
But the core approach remains the same, where multiple columns enable tracking notifications, messages, likes, mentions and more, for all your Twitter accounts.
Tweeten's interface can take time to master, but if you're a TweetDeck fan, or need its extreme configurability, the program should appeal.
