Is Duolingo good for learning Chinese? What its screens train, checked against the research (video)
Duolingo Chinese is free, habit-forming and about 6,000 words deep. But most answers are picked, not recalled, and no screen we found trains tones.

Start
Duolingo's Chinese course is free, and its word list covers about 82% of the words on HSK 4. Yet in the full Duolingo lessons we could count, in French and Korean, 21 of 25 answers were picked or assembled, not recalled. From SayMei Guides, by Mei Lin: is Duolingo good for learning Chinese? What its screens train, checked against the research.
The short answer
The short answer: yes, for starting Mandarin and building a daily habit. The whole course is free. But it's weak for tones, speaking and reading. Most answers are picked rather than recalled, free feedback shows only the right answer, and no screen we found trains tones.
Your goal decides the verdict
Is it enough? That depends on your goal. Trying Chinese, or travel basics? A good start. Holding conversations? Not enough on its own. Passing an HSK exam? Vocabulary yes, exam skills no. Reading Chinese? Weak. For any goal beyond a first try, plan to add something. How do we know? We didn't test Duolingo hands-on. We analysed hundreds of its screens from Mobbin, a library of app screenshots. Only 28 show the Chinese course; most others are French and Korean, which work the same way. The screenshots predate Duolingo's April 2026 Chinese expansion, and they carry no sound. And something missing from them isn't proof it's missing from the app.
What a lesson trains
Day one. Duolingo asks how many minutes a day you'll study, and its Chinese course page leads with five. That's a sensible way to start a habit. But ten minutes a day is about 61 hours a year. The US State Department budgets about 2,200 classroom hours for professional Mandarin. A year at ten minutes is under 3% of that. Then your first words. You hear 公园, park, and pick one of four pictures. The good part: almost every screen is a question, and across 222 classroom studies, testing yourself beat re-reading. The weak part: picking is recognition, and recalling an answer teaches more. You can show pinyin over new words only, a fade the research supports. Listening exercises have you rebuild a sentence from word tiles. But tiles are the default, and Duolingo's own engineers wrote that tiles and a keyboard need very different levels of recall. So switch on the keyboard. The same exercise becomes dictation: genuine recall.
Tones, recall and speaking
What about tones? The only tone-related Chinese item we found can be answered without hearing tones at all. A real tone item would offer one syllable four ways: 方, 房, 访, 放. In one study, eight sessions of tone training raised American learners' accuracy by 21%. With only 28 Chinese screens, that's a gap in a sample, not proof of a gap in the app. Now the count. Mobbin holds five complete lessons, two in French and three in Korean. In 21 of their 25 items, the learner picked an option or assembled tiles. Only four asked for production. Smooth practice feels like learning, and often it isn't. Get something wrong, and the free tier shows the right answer, without the reason. Across 40 studies, explanations helped most. Duolingo's are paid: Explain my answer opens an upgrade to Max. To be fair, each unit also has a free guidebook of tips, outside the lessons. Speaking mostly means reading a sentence aloud, and you can skip it. Duolingo grades Chinese speech phonetically, so he, she and it, which sound the same in Chinese, count as a match. We can't tell whether a wrong tone fails. Its open conversation, Video Call, was listed for Chinese on iOS, for Max subscribers, in January 2026. After one 58-second lesson we studied, eleven more screens followed: gems, the streak, quests and leagues. Streaks genuinely change behaviour, and that's Duolingo's real strength. But in Duolingo's own study, time on the app had very small and nonsignificant correlations with test scores. Put it all together. Testing yourself, fading pinyin and habit: it meets the research. Explanations, short grammar teaching and speaking with feedback: partly. Recall and reading volume: mostly misses. Rewards tied to learning: misses. And tone training: not seen.
How far does it go?
So how far does it go? In April 2026, Duolingo said its Chinese course now reaches B2. We matched a community copy of its word list, about 6,000 words, against the HSK 3.0 lists. It teaches 90% of HSK 1, 82% of HSK 4, 75% of HSK 5 and 48% of HSK 6. But we found no speaking-test or essay practice. It can carry your vocabulary towards HSK 4 or 5. It can't carry the exam.
No study of the Chinese course
Does it work for Chinese? Duolingo's efficacy page lists 20 studies and reports, and none evaluates Mandarin. Its strongest results are its own, from beginner Spanish and French, with learners who finished, paid $100 for the tests and sat no pre-test. So the evidence can't say Duolingo fails at Chinese. Nobody has measured what its Chinese course produces.
What Duolingo does well
What does Duolingo do well? It's free, with the same lessons for everyone. Streaks, goals and reminders are the best-engineered part of the app. It scaffolds beginners with pinyin, slow audio and pictures. It tests rather than tells. And it's deep: about 6,000 words. If it gets you studying every day, that alone earns it a place in your week.
Add what it leaves out
Add the four things its screens leave out. With half an hour a day, one reasonable split is 10 minutes of Duolingo and 20 on these. Tones: listening drills across many voices. Speaking: a tutor or partner who corrects you. Characters: write some by hand. Reading: stories at your level.
What to do next
What to do next? Keep Duolingo for the daily habit. Turn on the keyboard, and fade the pinyin. Train tones on their own. Speak with someone who corrects you. And for HSK, add the official word lists and sample papers. You can practise speaking with Mei Lin, SayMei's teacher, in a short spoken lesson at your level.
