The app offers flashcard-style exercises that include both Mincho and Kaisho styles, as well as stroke order, making it a comprehensive tool for beginners.

The app is user-friendly and easy to navigate, with a clean and simple interface. It offers different modes of learning, including quiz and practice modes, allowing users to test their knowledge and track their progress. Another great feature is the ability to customize the learning experience by selecting specific characters to focus on.

Overall, Hiragana Cards is an excellent tool for anyone looking to learn hiragana and katakana characters. Its comprehensive approach and user-friendly interface make it a great choice for beginners. The fact that it is free is an added bonus. However, it would be even better if the app offered additional features such as audio pronunciation and more interactive exercises.
