Help us improve the trainer

We built NativeTrainer: Chinese Tones to fix real spoken-Mandarin pain points—especially tones that fall apart in words and phrases. Your experience is our best compass.

  • Is a specific tone contrast still hard after a solar-term gate?
  • Want a word or phrase added to a later gate?
  • Is a feature not working the way you expected?

Please tell us. Every email is read by the founder and shapes what we ship next.
