I've been trying to learn Spanish on and off for years, and Duolingo has helped me build a basic vocabulary, but it's nowhere near enough to hold a real conversation. Apps make language learning feel easy and game-like, but they don't give you the messy, unpredictable exchange you get with a native speaker. Do you think language apps are a legitimate way to achieve fluency, or are they just a fun supplement that gives a false sense of progress?
