About

CantoDuck

Features
Read full description

CantoDuck is a playful Cantonese-learning app for families outside Hong Kong — for parents who want Cantonese to stay in the family. It is built around a Hong Kong street your family may be a long way from: taxis, dim sum, the tram. The words are everyday Hong Kong Cantonese, written in Traditional Chinese with Jyutping. • Tap a picture card to hear the word — from taxis and trams to dim sum, over playful Hong Kong-inspired backdrops. • Three-line learning — Chinese, Jyutping, and English on every card. • A dedicated Hong Kong Cantonese voice on every word — not your device's generic speech engine. Bundled in the app, the same on every phone, and it plays offline. • Record your own voice — a parent can replace any word's audio, so what plays back is mum or dad rather than a stranger. (Recordings stay on the device and are never sent to our servers.) • Echo mode — say the word out loud and get warm, non-punitive encouragement. • Family Tree — many relatives, so nobody is stuck guessing who is 姑媽 and who is 姨媽 before the next video call home. Premium is an auto-renewing annual subscription with a free trial. It unlocks every chapter and the extra cards in Our Words. Cancel any time in your Apple ID settings.
