Just amazing...

If you want to study hanzi for the HSK, this is the app to get. Not to complex so you dont spend all your time trying to get it to work, but just enough depth so it does what you want it to. The app just gets out of the way, so you can focus on your studies. I have Flashcards Deluxe, but this is the one I keep coming back to!
