Interesting, but not everyone can afford a VR. Especially the product is not for free, (its good to see that there is a trial) - the point is, its not for everyone. But you may still able to learn Geography or any Topics by searching the title on Youtube and add VR from the title just like this one.

You just need to buy a VR CardBox and also maybe a smartphone with a gyroscope ;) . Technically the app you hunted sir @mawahab is for Rich People.
