The aim of the application is to teach the common Cantonese words and to expand the vocabulary. Although the words included in the libraries sometimes have more alternate meanings, not all of them are listed as the application does not aim to function as a complete lexicon. Also, certain characters/words have more tones, though only one of them is listed. Upon building the word libraries the spoken versions had larger priority, so if a certain word has different written and spoken forms, usually the spoken version is included.

The word libraries are only in Cantonese - English, but the language of the application's UI can be switched between multiple choices in the Settings. Currently 2 UI languages are supported: English and Chinese (Traditional characters).


There are 3 kinds of testing modes:

Spoken Cantonese audio is played automatically for each word in Meaning and Listening modes, where at Listening mode the audio can be repeated any number of times. If you wish to use the app in such an environment, where silence is required, there is an option in the Settings for turning off the audio (or you may even lower the volume of your device). However, if the audio is turned off inside the app, the Listening mode will not be available for practice.

To start learning, you will have to choose a testing mode first and then a library, where its words will be used during the test. Each time a new test is started, the words are randomized. If you cancel the test or exit the app, the actual state of the test is saved so you can resume it anytime from the point where you have stopped. If you have finished a test and you had some incorrect guesses, then there is an option to repeat the same test just on the incorrectly guessed words only. You may keep repeating the test upon the incorrect guesses until you get them all right.

The top accomplished test rate for each library is displayed next to its name. This will indicate which libraries are already learned and where you need to put your focus on. These percentage rates are kept separately for each testing mode.

In case you find the text size to be a little small for you, there is an option in the Settings where you can choose between small (the default) and large texts. It will be applied to the Cantonese characters and some other texts used during the tests.


The app will keep you various statistics of your tests in the Statistics menu including the ratio of incorrectly guessed words. The stats of the last test are always available here in case you have closed the test results screen but need to re-check those data. Statistics are shown individually for all the 3 testing modes, where only the best result is kept for them.


The Library menu provides you a list of all the words that are available in the app. The words are categorized in different libraries, where most of them are having words in increasing difficulty. For example, the libraries Beginner I and II contain the most basic words that are recommended when you start learning the Cantonese language. While the libraries titled Expert are recommended for those who are somewhat familiar with the language. By selecting a library, the list of words is presented by the option of listening to the spoken Cantonese audio. Playing the audio is possible by tapping the individual characters themselves.
