Twitter has announced the launch of a new web app version of their homepage. It is accessible now at Twitter.com from your Android or iOS Device although it is being rolled out slowly to users so you may not see it right away.

The new interface looks incredible and very snappy, with a smart row of icons at the top that mimic the official Twitter app for the iPhone. The new client is built with modern browser technologies like HTML5 and looks like one of the best and most ‘native’ experiences I’ve seen yet in a web-based app.

Twitter says that the new app gives you access to your entire Twitter experience, including viewing, mentions, trending topics, search, lists and more. It was built from the ground up for mobile browsers and uses touch gestures and the full capabilities of modern devices larger screens.

This web app allows us to provide a high-quality and consistent Twitter experience on high-end touchscreen devices – whether or not an official Twitter application is available. It was built from the ground up for smartphones and tablets, which have more advanced browsers that support the latest web technologies, including HTML5.

The new Twitter app is not yet available to everyone but Twitter says that they are rolling it out today to a small percentage of users on iPhone, iPod touch and Android smartphones.
