Previously released on PS4 and PS3, the Twitch app is now finally available to download on PS Vita. For those that own a PlayStation TV, you also have the option to watch streams on a larger screen as the system is compatible with the app.
The app allows players watch live and recorded video of top games, players and esports events, follow channels and games you want to keep tabs on, and a special section to highlight PlayStation broadcasters. Unfortunately, you still can't broadcast PS Vita streams.
You can download the 16.7MB app directly from PlayStation Store.
