Today Sony announced the PS4 companion app for Android coming on November 13 (a bit later in Canada and Europe), just in time for the PlayStation 4 launch (Nov.15). The app will give you access to their PlayStation profiles and information but it will also offer second-screen functionality on both iOS and Android devices. The second-screen aspect will actually allow you to tune in and watch your friends play games and that is pretty awesome for a companion app feature. Of course it will also function as a remote control for your console.

Thanks to Kotaku we have the full feature list provided below and you'll see that the next generation is really going to use that smartphone of yours as a accessory. We did know something like this was coming but we weren't sure it would be here in time for the PS4 launch. So are you buying a PS4 and if so will you be using this app and your smartphone or tablet as a companion for it? Let us know in the comments.

Once installed, users can use their PlayStation App to control their PS4 system as long as both devices have access to the same Wi-Fi access point.
