Among the new features and improvements for the designed app are:

• Live video previews – check out live streams while you browse
• Better support for past broadcasts – see chat on offline videos
• Improved stability – the Twitch app has been rebuilt from the ground up to improve your viewing experience

Select Join. Once the registration process finishes you will be redirected to the Store page to install the Twitch Beta.
