Duolingo

Duolingo turns language learning into short drills, streaks and tiny daily lessons, so it is mostly for beginners and casual learners who need a nudge to keep showing up. By our assessment, its real strength is that it makes practice feel light enough to repeat, with listening, translation and matching tasks that remove a lot of the friction of starting. The downside is that it can stay too forgiving and too game-like, so speaking and free conversation need more than the app alone. In practice it feels like a phone habit: a few minutes, a few taps, a reminder that you have not broken the streak yet. Compared with classroom courses or dense grammar books, it is far less formal and far easier to return to, but also less complete. Duolingo is strongest as a starter and a companion, not as the whole road to fluency.
