Skritter is a focused learning tool. We don't want Skritter to teach every aspect of Chinese and Japanese. We want Skritter to help you learn and remember Chinese and Japanese characters better than anything else. We've done a lot of math to optimize your learning rate while letting you study anything--you learn the words that are important to you, as fast as possible. And we won't stop making Skritter better until Chinese and Japanese are easier than French.
