This VR-tour app allows you to go through the virtual apartment.
You need to launch the app and to set your device into the VR headset.
Special checkpoints will help you to move inside the apartments. You have to look at the checkpoint and wait while the progress bar is full. After you will move to the check point you have chosen.
In the app you can open the window and the wardrobe in the bedroom just looking at it.

Notice: be careful while using VR-tour, you can move in a real environment and hit yourself running into real objects.
