The "Enhanced Free Learning App for Core Kanji and Vocabulary" is designed to support the study of the top 2500 core Kanji characters and 1000 vocabulary words typically found in university entrance exams. The latest update brings improvements to group study features, offering enhanced data insights such as answer distribution graphs and editable test result exports in CSV format. Users can now manage test results within their created groups and access a variety of information to track their learning progress effectively.

This app offers three learning modes tailored to individual study preferences. Users can engage in a quick 10-question challenge, customize test parameters, including university-specific questions, and focus on overcoming weak areas through targeted practice sessions. The app also allows group creation for collaborative learning, enabling members to share test results and rankings. Visual representations of learning records, including graphs displaying memorized questions and university-specific progress, further enhance the learning experience.
