Your search for a reliable Cantonese dictionary ends with the Hanping Cantonese Dictionary mobile application. It is (exclusively!) downloadable on any compatible Android device for free. The app offers an extensive base dictionary with tons of words, various example sentences exhibiting usage, and audio files of spoken Cantonese syllables that are done by native speakers, among other handy features.

You will also find the live search function beneficial, especially if you are prone to forgetting the spelling of the word you are typing. And, if you have Google Translate installed on your phone, you can also enjoy the automatic translation of words.
