If you are using Heisigs Remembering the Kanji, aka "RTK" than this app is for you. There is also another app, the official version thats available, but it has an outdated list of kanji. This app has the latest list from the 6th edition of the RTK book.
The app is essentially a list for reference, but there is also an import and input function for kanji stories to help in memorization. I would like to see an upgrade that would include a flashcard review, a "random" flashcard option, but the app "as is" does an excellent job as a reference tool.
