Learn Real Japanese.

Flashcard Tree is a spaced-repetition system designed to improve your Japanese fast and efficiently. Study online in your web browser or on the go with our Android application. Flashcard Tree remembers how much you've learned and makes it easy to manage your learning content.

Spaced Repetition Systems are software algorithms that help manage the time interval between study sessions. The more frequently and easily you remember something, the less frequently you need to study it. Flashcard Tree manages all of your flashcards and schedules them for future review based on whether or not you remember them.
