I'm a language learner myself, and I also frequent various reddit language subreddits and read all the stories of other people. My belief is that "don't have time" usually means "I've lost motivation after the initial high". A huge problem with language learning is that unless you have moved to another country or otherwise in an immersive environment then it becomes quite difficult to keep motivation and discipline high. The reward of "I can read/write/speak/listen a little better than last month" starts to pale and people realize they actually don't use their new skill on a regular basis. And like many things, getting to the next proficiency level takes increasing amounts of work. The flip side being that for X weeks of study less and less progress seems to be made. What I'm getting at is that this churn is not a problem with your product, but a broad problem with language learning. Anything you can do to solve (or lessen) these problem is a big, uncertain task. But it's probably the only way to reduce churn. The upside is that if you do manage to make headway then you've done something major. Really major.
