Popular Chinese smartphone-maker OnePlus has finally released the official cardboard VR app ahead of OnePlus 2 unveiling.

Early in the month, the company gave out free VR set made of cardboards to fans, now the smartphone app has been made available on Google Play store.

"Once you've downloaded the app, you won't be able to see much. But come July 27, 7pm PT, the OnePlus 2 keynote will automatically start streaming. You'll have front row seats to the world's first product launch in VR," said official OnePlus forum administrator Cat H.

With VR cardboard and the smartphone app, people will get a sense of immersive feel of watching the event right in front of your eyes. OnePlus fans, who failed to get their hands on the cardboard VR set, need not be worried as the OnePlus 2 Launch app also comes with 'Cardboard-free 360 experience'. It won't be as immersive as being watched on VR set, but its interface will certainly be interactive, says the company.
