Currently, we can only read and listen to the Kanji characters in the Writing Lessons. For practice, I write on papers. At the end, we can just evaluate our progress by setting the lesson to "Read".
I would like to suggest if Rocket Japanese can add a "Draw It" test to evaluate the students whether they really know how to write Kanji. The students can use their mouse or a Stylus Pen to write on their computer or tablet. This will be more challenging to the students.
Adding a "Draw It" test in Writing Lessons

I agree and have suggested this as well. I also suggest they add a testing tab to the writing lesson with the full complement of tests. As for drawing the characters, in Google Chrome you can install "Google Input Tools" and use their drawing method for Japanese or Chinese.
