Cool but
This app is great! But, I paid for the premium version to get full access. That was fine until they changed over to a subscription model for any new lessons. And the only way to get credit for the previous premium purchase was to buy a full year subscription for $49.95. Then they only added two more lessons.
It would be fine if the subscription to their other services carried over to this one -- I am already paying $49.95/yr on the iPad for their full service. But I really like the lessons and simplicity of this version more. Plus it works great on the go.
