Japanese Kanji Flash Cards, developed by Nahu Studio, is an educational app designed to help users learn and memorize Japanese kanji characters. The app is available for Android 13.0 and is completely free.

One of the main features of the app is the ability to select the level of difficulty that best suits the user's learning needs. Users can then select flashcards from a list and mark the kanji they know with a green checkmark. The app also allows users to look up the meanings of kanji and try to remember them. Once a user has completed 100% of the flashcards, they are considered to have learned the kanji.

The app has recently added new features, including an auto-run stroke writing animation and various check types for practice with a cumulated result view. Users can also practice writing kanji with the app.

Overall, Japanese Kanji Flash Cards is a useful and efficient tool for those looking to learn and memorize Japanese kanji characters.
