I'm making an app like this for Japanese, however it doesn't have preset lessons yet. (I'm planning to add more structured lessons in the future.) For now what I have are a bunch of vocabulary lists for various shows/novels/etc. which you can pick and learn the vocabulary from, and then you can use the app to find the next show/novel/etc. where you'll have to learn the least amount of new vocabulary to be able to consume it.
