For a beginner of learning Chinese, this app is definitely recommended.
When you first start to learn a foreign language, usually you are directly taught the vocabulary or alphabet.
However this app introduces the original Chinese categories and complicated Chinese characters and Pinyin system in an easy understandable way.
You can listen to the tutor for introduction, and then you can learn by each lesson to see the Chinese character varied form and the meaning each represents.
Lastly you can take a quiz to make sure you are familiar with the Chinese language system. If you are a quick learner, I believe you can move on to the iStart Chinese full version to learn more.
