Twitter had this to say about the app;
Twitter via GigaOM"The app is fast – you can quickly scroll through your timeline, move between tabs and compose Tweets. It’s rich – it takes advantage of capabilities that high-end device browsers offer, such as touch gestures and a large screen. And it’s simple – it’s easy-to-use and has the features you’d expect from a Twitter application, including your timeline, @mentions, messages that you can read in conversation view, search, trending topics, lists, and more."
