The app is full HTML5 and an improvement over the current one-paned experience of the Twitter mobile site on the tablet. Not surprisingly it is reminiscent of a hybrid of Twitter.com and the mobile apps and was based on Twitter's HTML5 client for iPhone and Android, Twitter mobile engineer Manuel Deschamps tells me. The HTML5 web app will be rolled out to all users within the week, eh hem, beating Facebook which has yet to launch its own HTML5 initiative Project Spartan.
Twitter representative Carolyn Penner told the site, "The HTML5 app provides a great option for people who prefer to use the browser over native apps. Its two-column view is consistent with the Twitter experience you're used to (on Twitter.com), and it takes advantage of touch gestures and other device capabilities."
The new web app is being rolled out slowly but everyone should have access to it within a week.
