To tell the truth, this app is far more than the other similar ones. The app's user interface is designed well, optimized for IOS7 so you could get a fresh interface which is used simply. It's a good teacher for my children, giving them a lot of suggestions to communicate with others. At the same time, this app provied some knowledges of daily life, which is very helpful for them. Also this app's price is expensive perhaps, I think you can get more excepting the price.
