No longer work

They were great apps to help with science, but after the iPhones latest update, the apps open up and the pictures spin-nauseatingly fast! If this is to get fixed I would totally recommend this product but as of right now I can no longer do that.

Good concept but...

We got several books of this series and we were very disappointed that the VR doesn’t cover the contents of the books. Rather, it only covers a very small portion of it.

I am Liam and I love this game ,


I already know so much and this app is giving
me so much more information!!!!!
