HSK One vs Duolingo vs HelloChinese — Honest Comparison
Quick Answer: HSK One is a free, HSK-aligned course platform: full HSK 1–9 curriculum, mock tests, and SRS flashcards with no account or payment. Duolingo builds daily habits but isn't HSK-structured. HelloChinese offers richer media behind a subscription. Choose HSK One if your goal is passing the HSK exam for free.
Different tools solve different problems. Here's an honest breakdown of where each platform fits — including where HSK One is NOT the best choice.

When to Choose Each Platform
- HSK One: you have an exam goal (HSK 1–9), want structured lessons + mock tests, and don't want to pay or create accounts
- Duolingo: you want a lightweight daily habit and aren't targeting the HSK exam specifically
- HelloChinese: you prefer video-heavy, immersive lessons and don't mind a subscription for full content
Where HSK One Is Honest About Limits
- All 9 levels are live (10,969+ words) — but HSK 3-9 lessons are vocabulary-and-exercise focused while dialogues and stories are still being enriched
- No live tutor or conversation practice (yet)
- TTS audio instead of studio-recorded native speech
- Daily streak tracking is on-device only, with no push reminders yet — create a free account to sync your progress
Tip: Many learners combine platforms: HSK One as the exam backbone + Duolingo or HelloChinese for extra exposure. That's a valid strategy — the structured course should be the one you finish.
Frequently Asked Questions
Is HSK One really free while others charge?
Yes. Core learning on HSK One is free by design — lessons, exercises, flashcards, and mock tests. No subscription, no account, no ads blocking content.
Is Duolingo enough to pass HSK 1?
Not reliably. Duolingo doesn't follow the HSK syllabus, has no mock tests, and its Chinese course doesn't cover all 150 required words in exam format. It's a good supplement, not an exam backbone.
Is HSK One better than Duolingo for HSK prep?
For exam preparation, yes. Duolingo doesn't follow the HSK syllabus, has no mock tests, and its Chinese course doesn't cover all required words in exam format. HSK One is purpose-built for the HSK exam. Duolingo is a good supplement for daily habit building.
Can I use HSK One alongside a tutor?
Yes — that's ideal. Use HSK One for structured vocabulary/grammar/exam practice and your tutor for conversation and feedback.
