小学３年生漢字：ゆびドリル（書き順判定対応漢字学習アプリ） 5.6

This is a comprehensive review of a highly advanced kanji learning application designed to enhance students' writing skills and recognition accuracy. The app has achieved notable success, previously ranking first in the education paid iPad App category on the App Store with over 460,000 downloads across its series.

The application emphasizes the correct formation of kanji by utilizing textbook-style fonts that accurately reflect proper stroke order, including accurate handling of hiragana. It covers all 200 kanji characters taught in third grade elementary school, allowing learners to develop foundational literacy skills effectively.

Users can practice writing kanji directly on the screen with their finger, and the app intelligently recognizes and scores their input. During drill exercises, the app enforces correct stroke order; unless the character is written correctly in sequence, it does not mark it as correct. The practice module provides immediate feedback on stroke order and stroke count errors, ensuring high-quality learning experiences through continuous verification of proper writing technique.

Feedback from several educators highlights the app’s precision and potential for classroom application. A primary school teacher remarks on its excellent handwriting recognition capabilities suitable for educational purposes. Others mention its usefulness for after-school tutoring sessions and its positive impact on student concentration, especially in special education contexts. An American school teacher notes increased motivation among children to actively write kanji, while a reviewer from AppBank suggests that pairing the app with a stylus could further enhance its effectiveness.

Highlighted features include:

• Writing Drill: Practice writing kanji by tracing characters on the screen, with strict verification of stroke order and count. Characters must be written correctly to be accepted.
• Reading Drill: Write the readings (kun'yomi and on'yomi) of displayed kanji characters in succession, promoting vocabulary recognition.
• Practice Module: Review stroke arrangements with model examples and repeatedly write kanji. Up to ten personalized characters can be saved per character, encouraging mastery through repetition. Completing ten repetitions earns a small medal, motivating sustained effort.
• Performance Reports: Access detailed results including scores, number of attempts, dates, accuracy rates, as well as lists of incorrectly written characters and readings. Relearning is simplified by directly revisiting problematic exercises.
• "Chikara Dameshi" Function: This mode offers 20 randomized questions for both writing and reading drills, designed to reinforce memory retention through varied practice.

Regarding stroke order and character recognition accuracy:

• If both stroke order and stroke count are incorrect, priority is given to displaying the stroke count error.
• Incorrect recognition may occur if a user’s trace deviates significantly from the model or extends outside designated boundaries during practice.
• The app does not evaluate the correctness of hiragana stroke order or handle specific 判定 for はね（hane）and とめ（tome）in accents or cursive writing.

The application has been well-received by educators across various levels, praised for its quality handwriting recognition and interactive learning features. Its thoughtful design ensures engaging and effective kanji education suitable for both classroom use and independent study.
