Most apps tell you how many words you've seen. Aelu tracks your readiness across vocabulary, listening, reading, and tone accuracy — so you know what to study, not just what to review.
Free for HSK 1-2. No credit card required.
You might know 600 words but still fail HSK 3 — because the test measures four distinct skills. Aelu tracks all of them.
Not just "have I seen this word" — can you recognize it in context at speed?
Can you catch the meaning at natural speaking speed, not just slow textbook audio?
Can you read a passage without stopping to decode every other character?
The silent killer on HSK listening — can you distinguish tones in connected speech?
The new HSK standard makes the HSKK speaking test mandatory from Level 3 onward. Aelu already includes speaking drills with tone grading — so you're preparing for the new standard, not the old one.
The vocabulary lists are changing too. We're tracking every update and adjusting our curriculum as the standard finalizes.
