Excellent Tone Trainer!

This App is excellent! I like the fact that if you choose the incorrect tones, it lists the correct ones! Also I love all the Trainchinese Apps and so much so that I actually upgraded from the free version $$ and I rarely do that! All the trainchinese Apps are designed to work in conjunction with each other and I have all of them!
