This app is a great introduction to the Crow language as well as the culture. It is easy to use and replay is very smooth, which is very helpful for practice. You won't get fluent from this alone, I'm not even sure you will become conversational, but because it sticks to the basics, it's not overwhelming or intimidating. This is the perfect app for people to access and become familiar with a language that so few are even aware of. I hope more like this are made for the other American languages and even a more advanced version of this would be great!
