This is a great library for learning Data Science / Big Data.
And the availability of the iOS app for learning will be really helpful to some of us working professionals, who want to make this change towards Data Analytics.

I agree... I always have to use my laptop to learn from cognitive website; it would be a lot better if there was an IOS app for easy access. Especially on days when my laptop isn't available and I want to advance my knowledge.
