The Twitter app for Zune HD is a freely downloadable app available directly from the Zune HD or through the Zune desktop software. It exists among a handful of other apps for the Zune HD, most of which are games.
Upon launching the app, users are asked for their Twitter account log-in and password, which is saved on the device for all future log-in sessions. Use of the Twitter logo and bird mascot are an indication that the app was developed officially by Twitter.
Creating a tweet pops up a portrait-oriented keyboard. A tab within the tweet window switches between general messages and direct messages. Beneath the tabs are buttons for adding users to the message with @ replies, or inserting the title and artist info of the currently playing song.
Just a quick comparison shot of the Zune HD Twitter app next to the Twitterific iPhone app. Both apps offer similar functionality, but the iPhone offers several Twitter apps that cater to different types of users.
