Great App! I thought the lessons were well commented and laid out. One trick, instead of bulking up with more features, it to lay out more lessons and publish a system for letting us know when they're available. For me it would be more useful if the lessons came in similar large blocks/iterations with a predefined goal of "by taking these lessons you will learn X". Anyhow, great work!
