It's a great app and has legitimately helped my Spanish reading and writing performance. Lessons do sometimes get extremely repetative and I am looking forward to seeing how they use AI to increase the range of lessons, especially with regards to spoken skills.
Decent as a crutch for learning languages, although you should also practice the languages outside of it. It can be unstable at times, although that seems to be improving in recent versions.
I adore Duolingo! I even feel as an ambassador because some of my friends also join studying after me.
What I like the most is that Duolingo constantly evolving their mechanics. So you won't be bored.
I'm with Duolingo since 2016, finished Italian course twice! And now I'm also have more that half of a thousand streak.
Duolingo helps me to be multilingual
My phone's language setting is in English, but I still want to learn English using Duolingo. However, the app doesn't allow me to select English learning options without changing the entire phone's language settings.
