Works fine for me

This app is working fine for me and I think its great if you are just starting to learn Chinese. I have trouble distinguishing between the 2nd and 3rd tones, but this app has helped. If you forget how certain letter combinations are pronounced just open up the app and find what your looking for.
I think it would be nice if the app had a testing mode, where you could guess what the sounds were and be able to write the answers in to make it a little harder.
