App: Learning English In Image for everybody

I have just finished my first app . It is about learning English in image. It is a great idea to help people study vocabularies through corresponding pictures. It helps students easily remember the words by the appearance of the pictures in their mind.

The app have 3 function: learning lesson, do testing and play game.
Every lessons are covered in specific topics. And now it has 60 topics ( i will update more soon).
This app support for android from version 2.1.
Hope that everybody try to use it and give me your comment, so i can fix and make my app better and get more experience.
