Horribly unstable, but content is good

It gets only three stars because it is HORRIBLY unstable. Using it with an iPad Mini on wifi or a iPhone 4S on 4G - it CONSTANTLY crashes. This is made worse by the fact that if you are in the middle of one of the apps "tours" you have to start all over. And as you go forward to try and find your spot… it crashes again.

That being said, the content is excellent. Just wish it was possible to actually take one of the apps "tours" to completion.
