A unique question-setting algorithm based on the forgetting curve allows you to quickly and repeatedly study 2,000 kanji questions that frequently appear on high school entrance exams.
Because it's a self-grading system, if you completely memorize a kanji question, you can immediately tap "Correct" to continue practicing questions one after another, allowing for speedy study similar to using a vocabulary book.
If you get an answer "Incorrect," the app will automatically prioritize the next question at the appropriate time the following day, ensuring thorough mastery.
(A question you answered incorrectly will be presented one day later. If you answer correctly, it will be presented three days later, and if you answer correctly the next time, it will be presented again, and so on. This question-setting algorithm is based on forgetting curve theory.)
In addition, the app features courses for "Questions you got wrong today" and "Questions marked as difficult (manually registered)," allowing for thorough review.

You can also register your own questions.
You can register an unlimited number of custom questions for free, and, like the Auto-Master course, you can study based on the forgetting curve.

・About the Self-Grading System
This app has a handwriting space in the answer section, but it does not have an automatic character recognition scoring function.
We use a self-grading system where you view your answers and tap "Correct" or "Incorrect."
This is because there are concerns that using automatic character recognition to grade your answers would:
- Slow down your learning speed because you have to write everything by hand
- Waste time answering questions you completely remember
- Result may not reflect your true ability, such as when a kanji you wrote with a vague memory is marked as correct
- There is a risk that the character recognition system will make an incorrect judgment

Since this is a self-grading system, we believe it is important to be strict with yourself.
(If you are unsure, we recommend tapping "Incorrect.")
