Wow, nice app! I tried the Chinese version on my 3g, I like how it has male and female voices, and the images and design was top notch. I tend to like the immersion style, it's how children learn basically. I can see this really being successful for travelers and kids, especially as software like rosetta stone is so expensive, and this seems at least on par if not better (from what I've seen so far). Bon chance! Are you planning other languages?
