"Excellent tool to master Chinese pronunciation"
This is the best tool I found to master Chinese pronunciation and tones. It's systematic. There is a comprehensive course on pinyin as well as tones, but the real winner is the vocabulary for each HSK level. The app has great recordings to teach. Sometimes it is too strict in evaluating my pronunciation, but it works, as I make progress easily and as it corrects some bad and lazy habits I had acquired while I have been studying Chinese (my level is HSK 4). Highly recommend to any student of Chinese.

"Best Chinese pronunciation app!"
There's lots of Chinese Pronunciation apps out there. I've tried pretty much all of them. This one is by far the best one! It has a pretty generous free version, and I'm definitely getting the paid version as soon as I go through all of the HSK 1 vocabulary. I love that it lets you listen to each of your words separately to compare against a native speaker. Thanks for making this!

"Convenient on practice Chinese speaking"
Easy to practice with high-quality standard audio for reference. Let friends who speak Chinese well try this, they said the response is accurate. Will continue to use it to see whether it can help to improve my Chinese speaking or not. ✊

"One of the very few apps that focuses on Putonghua"
One of the very few apps that focuses on Putonghua pronunciation. I especially like that it works offline and, unlike most training materials, features a male speaker.

"ピンインや声調の練習があるのが良い"
ピンインや声調の練習のところで声調を試してみました。さらっと解説だけで終わっているアプリが多いと思いますが、発音して判定する機能があり、探していた機能そのものでした。また、聞く力もクイズ形式で出てくるため、十分な機能があると思いました。
