I bought this app because I wanted to be able to review the HSK vocabulary lists and also practice writing and recognizing characters. After thirty minutes with this, I can see that it has the potential to suit my needs, but the interface is so confusing that Im not sure how to make it work. None of the icons are labelled so its a bit of a guessing game to navigate between the different features.
Additionally, it was advertised as an iPad app but it is in fact an iPhone app. I am disappointed about this because part of what makes it hard to use is the fact that everything is so compressed on the screen. If it took full advantage of the iPads larger resolution it would be a lot easier to use, I think.
Also I find it crashes fairly frequently, which is only a minor annoyance.
On the plus side, this app is a great resource for anyone studying Chinese because it has all the major vocabulary lists, it shows you how to write each character step by step, it includes comprehensive dictionary entries that encompass meaning as well as common phrases, and it speaks. This is what you pay for, and in this respect its a solid study aid. I only hope that future versions of this app will make its interface more user friendly.
