What is PortalVR? PortalVR is a modified version of the Monado OpenXR runtime that lets you run compatible XR games and apps on your Android tablet or phone. Use any phone—iOS or Android—as a controller to play installed or sideloaded titles as-is.
What hardware do I need? You need at least one modern Android device to run games and any ARCore- or ARKit-compatible phone for the controller. Most current phones (iOS or Android) work great.
What accessories do I need? If you're using a tablet or a larger phone, a pop socket makes it easier to hold, and green-magenta 3D glasses can be worn for full stereo 3D. (It's pretty cool.) Check out the PortalVR Essential Gear list.
