You can quickly and repeatedly study 1,800 frequently appearing kanji questions for junior high school entrance exams using a unique algorithm based on the forgetting curve. Since it uses a self-assessment method, you can tap "correct" immediately for kanji questions you know well, allowing for speedy study similar to flashcards. If you select "incorrect," the app will prioritize the question at the appropriate timing the next day and beyond, ensuring solid mastery. (Incorrect questions are presented the next day, and if answered correctly, they reappear after three days, following a forgetting curve-based algorithm.) Additionally, you can thoroughly review using the courses "Today's Incorrect Questions" and "Manually Registered Weak Questions." From version 2.0.0, you can also register your own questions! You can freely and unlimitedly register your own questions, and study them based on the forgetting curve, just like the default mastery course. About the Self-Assessment Method: This app includes a handwriting space in the answer section, but there is no automatic grading function using character recognition. You will assess yourself by looking at the answer and tapping "correct" or "incorrect." This method is used because automatic grading via character recognition: Requires handwriting for all answers, slowing down learning speed. Wastes time on questions you know perfectly. May not reflect your true ability if you write characters hesitantly. Carries a risk of incorrect judgments by the character recognition function. Since it is self-assessment, it's important to grade yourself strictly. (If unsure, it's recommended to tap "incorrect.") Learning Courses: This app includes the following learning courses: Mastery Course: This mode presents all registered kanji questions using a unique algorithm based on the forgetting curve. Each set contains 20 questions. Mastery level changes based on correct or incorrect answers. Today's Incorrect Questions: This course reviews questions you got wrong in the mastery course that day. Mastery level does not change based on correct or incorrect answers. Manually Registered Weak Questions: This course reviews questions manually registered as weak points. Mastery level does not change based on correct or incorrect answers. Premium Plan (Ad-Free): This app allows free use of all features, but subscribing to the Premium Plan removes all in-app ads.
