If you've ever wanted to learn a language but don't want to be tethered to a PC or stuck in some classroom, this might be your lucky day. Rosetta Course has just launched on Android, and you can try it out for free. You are welcome to choose from more than a dozen languages to explore, but only the first few lessons are available without paying up.

Rosetta Course uses a combination of text, images, and speech to help you learn the ins and outs of a new language. The speech features should work on almost all devices, and those with a stylus can also do writing exercises. Rosetta incorporates additional speech recognition technology to assess your pronunciation as well.

The app's interface is a little chunky, and it won't suspend in the background very well. You'll have to restart the app when you're pulled away. I also don't see a way to buy the full course from within the app – not even a link. If you want to buy access, just head to the Rosetta site. Be warned, it's expensive – on the order of a few hundred dollars for a full course.
