Immersive Duolingo

I've never had the chance to try the Duolingo app, but I've heard great things about it. Some people swear by its ability to teach you a language through bite-sized and gamified lessons, and I can see why it works.

I had an interesting thought: What if Duolingo started to change your app's preferred language as you progressed through the lessons? This would force you to immerse yourself in the language you're learning. For example, if you're on lesson 10 of the German course, you might start to notice that "Home" is now called "Heim"... and so on.

It would definitely be more challenging to navigate the app and accomplish your tasks, but the experience and challenge of working through it could be invaluable.
