==Which versions support AR (Augmented Reality)==
 +
On Android it's supported in this app: https://play.google.com/store/apps/details?id=org.geogebra.android.g3d
 +
but your phone/tablet needs to '''support the ARCore Library''':
 +
https://play.google.com/store/apps/details?id=com.google.ar.core
 +
 +
You can check a list of supported devices here: https://developers.google.com/ar/discover/supported-devices
 +
 +
On iOS https://itunes.apple.com/us/app/geogebra-3d-graphing-calc/id1445871976 you need to have a device with iOS 11 that supports ARKit ie '''iPhone 6S / iPad 5 or later''': https://developer.apple.com/library/archive/documentation/DeviceInformation/Reference/iOSDeviceCompatibility/DeviceCompatibilityMatrix/DeviceCompatibilityMatrix.html
