Twitch has launched a full-featured PS4 app that lets you tune into any stream on any platform.
Twitch streaming was available earlier, but PS4 users could only view live streams restricted to PS4 games by using Live form PlayStation or Ustream.
Earlier at TwitchCon, Twitch mentioned that all PlayStation consoles will receive the new dedicated app. PS4 seems to be the first to receive it with PS3 and Vita versions coming later this year.
As of now, the app is only available to North American audiences, but will hit other regions as the roll out continues.
