We explain the meanings of the recurring components (radicals) for all HSK hanzi characters and offer a mnemonic phrase for easy memorizing that hanzi character.

Draw the hanzi on the screen and you will get a feedback if a stroke was wrong to improve your hand-writing.

Select a radical and learn all hanzi using this radical in a row. This is excellent for memorizing the characteristic differences.

The app comprises not only the HSK chracters but a total of more than 4000 hanzi characters.
