* Memorise characters using your motor memory... by DRAWING them!
* Learn correct pronunciation with ASR (speech recognition) and TTS (speech synthesis).
* Test your pronunciation of Chinese words including tone.
* Asks you to speak complex sentences, listens to your pronunciation and tells you if it was correct.
* Draw characters stroke by stroke and the handwriting recognition will recognise them.
* Informs you if you have pronounced a word correctly and if not, what it sounded like (pinyin and character).
* Uses proprietary linguistic algorithm for tolerance of learner’s accent.
* Both traditional and simplified Hanzi characters.
* Based on the HSK (Hanyu Shuiping Kaoshi) levels for Chinese language proficiency.
* Also subject specific test modules such as large compound numbers (including financial numbering system), festivals, business vocabulary and much more.
* No ineffective flashcards... the only way to learn to READ and WRITE Chinese is by practicing DRAWING the characters.
* Lets you view which characters you’ve learnt and share your performance with friends.
* Allows you to copy characters, share on Facebook or even send to your favourite Chinese dictionary app such as Pleco!

REQUIREMENTS
* Your phone should support Chinese character handwriting recognition (Chinese input method). If it's not already there you can enable it by searching Play Store for Google Pinyin Input and installing it.
* If it's already on your phone you can find it under Settings -> Language & Input -> Keyboard & Input Methods if you look for Chinese or Pinyin.
* Your phone should also support Mandarin Chinese ASR and TTS.

TROUBLESHOOTING
* In order to make the speech recognition work, you will need to go to Settings -> Language and Input and make sure that ASR is enabled and Chinese ASR is installed. You may have to select to enable ASR for Mandarin or Chinese. The language may be labelled either 汉语, 中文, or 普通话...
* Make sure you haven't installed Japanese by mistake! If you want to learn traditional Chinese make sure you have the correct variant of Chinese installed.
* If there's an option to download Mandarin ASR for offline use then try that, otherwise you won't be able to play the game without an internet connection.
* If the character recognition doesn't work or gives an error, then make sure Google Pinyin Input is installed and enabled in Settings. To switch your keyboard to character recognition you may have to hold down the space bar to select Chinese language, then there should be an option to select input by drawing character instead of Pinyin (typing letters).
* You should make sure you are inputting characters by drawing them, as the point of this app is to learn how to write Chinese characters!
* In any case, if you only want to practice speaking, or only writing, or your phone doesn't support one of these functionalities, you can select only speaking or only writing in the main menu.
