In my humble opinion, its the best language learning app out there. I started using langua 1 month ago and my improvements have been tremendous. I went from barely knowing 'what's your name' to holding conversations about basic topics. The AI chat is super easy to use and has tons of features, like instant translation, corrections, and personalized feedback reports...My spanish teacher and friends are amazed by my progress! I'd say Langua is about 15 times more effective (and 3 times as fun) as Duolingo. Highly recommend!
