Hello parkoma,

Ground Plane is compatible with non-ARKit iOS devices and Android Devices in Vuforia 7.0.43 which is currently available for native development on our downloads page and will be available in an upcoming Unity 2017.3 patch which will be released in January. For more information on the mapping of device support to Vuforia version, please refer to this document: https://library.vuforia.com/articles/Solution/ground-plane-supported-devices.html
