Does Arkio only work on VR headsets?

Arkio is also available in "desktop mode" on PC and Mac as well as in tablet and phone versions for iOS and Android. So you don't need a VR headset to get started. You can download Arkio for free on various devices at arkio.is/download

If you plan to do heavy 3D modelling with Arkio, we recommend using the VR version, as it includes additional modelling tools and functionality, and you can use your hands to grab objects and model more intuitively. An overview of VR headsets that support Arkio can be found here XR hardware
