漢字部首帳 is an educational app developed by KuroHebiSama for Android devices. It is designed to help users study kanji radicals, making it a valuable tool for those learning Japanese or preparing for the kanji proficiency test.

The app organizes kanji characters based on their stroke count, with three layers of categorization. The first layer categorizes kanji based on the number of strokes, allowing users to easily find characters with a specific stroke count. The second layer provides a list of radicals for each stroke count, helping users understand the structure and meaning behind kanji characters. Finally, the third layer offers a comprehensive list of kanji characters for each radical.

Please note that some kanji characters may be currently hidden as the developer is in the process of organizing them. However, this does not detract from the app's usefulness in studying kanji radicals.

Overall, 漢字部首帳 is a free app that provides a valuable resource for anyone studying kanji or looking to improve their Japanese language skills.
