Hi, Liz. Beluga is not yet available. We are delaying launch for a short while - it should go live in early September. The app that you have seen in the app store was an old test app that we built a while back to test the technology. It is nothing like the maths learning world that we have now built, which I have previewed at a few conferences lately. I'll let everyone know when the app is available. It will be entirely free and will cover the entire maths curriculum from the very basics of understanding what a number is, sorting, counting, etc... through to mid level calculus. I have written a few blogs about it on our site to describe what we are doing.
