Why do some sentences have no built-in audio?

To keep the app a reasonable size, 7,800+ HSK 1 sentences ship with AI-generated pronunciation audio (Kokoro TTS). Other sentences use your phone's Chinese text-to-speech voice. On Android, if no Chinese voice is installed the app offers to install one (system Settings → Text-to-speech).

Some Vietnamese translations look off?

Some translations are machine-generated. We improve based on user feedback. Email us any obvious errors — they'll be fixed in the next update.

How do I delete all learning data?

Go to Settings → Clear learning data. Or uninstall the app.

What languages are supported?
