Good app but room for growth – Pinyin Puzzle: Practice Mandarin Chinese on the go Review

This is a well designed app that goes great with MandarinX's edX courses. However, there isn't much to the app. It would be nice to see the words I got wrong at the end and the right answers. Rather than just having numbers for the tones, it would be nice to have the tone markers either above the button or as the button itself. The app only shows the character, but maybe it would be nice to show the pinyin (without tone marks) as well. Lastly, some of the vocab doesn't correspond to the correct lesson. Overall, good app, but lots of room for growth in further updates!
