Hey Product Hunt!
We launched YuYin on iOS in February. Today it's on Android too.
YuYin is built around one idea: you only learn to speak Chinese by speaking it, and you need to know exactly what went wrong.
What it does:
• Read a sentence out loud and get a score for every character: accuracy, fluency and tone, so you see which syllable was off
• One short dialogue a day: listen, learn the new words, shadow each line, then play a role
• Tone drills that show your pitch curve next to the target tone
• Out-loud conversations with an AI partner: ordering food, checking in, asking for directions
• Graded HSK 1–3 stories and stroke-order writing for HSK 1–6
Free to start (HSK 1–2 and daily practice). Pro unlocks every level, with a 7-day free trial on the yearly plan.
I'd love your feedback, especially on how the pronunciation scoring feels on your phone. What would make you practise Chinese every day?
