Version 1.0 went live about 10 days ago.
From the iTunes App Store Description:
AR Globe allows users to explore historic and old globes in their own space.
The old globes float in your room in front of you – you can move towards them and around them using your screen, as well as move inside of them. They can be zoomed in and out and turned as well. 7 different globes can be explored in great detail. AR Globe is both an educational tool for understanding history and a wonderful game at the same time.
AR Globe is free to download and use.
