This is a tool created for myself to practice and learn japanese kanji words.
The kanji symbols are extracted from Jim Breen's kanjidic library, and grouped by the JLPT (japanese language proficiency test) levels.
The app is free, even no ads, though you can donate on paypal to firstname.lastname@example.org
