It has all of the features you’d come to expect from a Twitter client. Most importantly it allows you to manage and post to multiple Twitter accounts.
After you log in you’ll find four main buttons: Tweets, Replies, Messages, and Favorites.

Each tab shows you 20 results at a time, but you can see more with a single click.
You can do a lot with this Twitter app including viewing reply chains, see links directly in the browser, retweet messages, turn links in the browser into short URLS and more. The only thing that this app doesn’t do is let you browse the web and shorten a URL.
