You can quickly and repeatedly study 1,800 kanji questions that often appear in junior high school entrance exams using a unique question-taking algorithm based on the forgetting curve.
Since it is a self-grading system, if you have a question with a kanji that you have completely memorized, you can quickly tap the "correct answer" and go through the questions one after another, making it possible to study quickly like using a vocabulary book.
In addition, if you get an incorrect answer, the app will automatically prioritize questions at the appropriate time from the next day onwards, so you can expect to improve your skills.
(We use a question algorithm based on the forgetting curve theory, such as incorrect answers will be asked one day later, and if you answer correctly then three days later, if you answer correctly the next time...)
In addition, courses such as ``Problems I Wrong Today'' and ``Problems I Registered as Bad (Manual Registration)'' have been implemented, allowing thorough review.

Starting from version 2.0.0, you can also register questions that you have created yourself!
It is possible to register an unlimited number of self-made problems for free, and learning based on the forgetting curve is possible in the same way as in the conventional automatic mastery course.

・About self-grading method
Although there is a handwriting space in the answer column of this application, there is no scoring function based on automatic character recognition.
We use a self-grading method (tap "correct" or "incorrect" on your own) while looking at the answers.
In the case of scoring using the automatic character recognition function,
-Learning speed slows down as everything must be handwritten
- Wasting time answering questions that you have completely memorized
・Your true ability may not be reflected, such as when the correct answer is a kanji you filled in with a vague memory.
・There is a risk that the character recognition function will be incorrectly determined.
This is because there are concerns such as:

Since it is all a matter of self-grading, I think it is important to be strict with yourself.
(If you are not confident, we recommend tapping "Incorrect")
