The main goal of Skritter is writing practice, however I have been highly impressed by the good quality of sound, it had helped me a lot to overcome the pinyin bad habits. My mother language is Spanish, so unfortunately I have a very nasty trend to read pinyin as spanish letters, but Skritter is helping to overcome it.
I have a wish, however, would it be possible to get a REPLAY SOUND button when we have just finished a word practice?
