The full HSK syllabus, one glance at a time. A word waits with its pinyin; one tap reveals the meaning and a real sentence.
Pinyin shows on the question side, so you can say the word out loud without leaking the meaning.
说话
shuōhuà
A word from your level, waiting on the screen you look at anyway.
“To talk? To speak?”
Say it before you tap. That small moment of recall is what makes it yours.
to speak
不要说话。
Bù yào shuōhuà.
Do not speak.
One tap on the bolt and the feed deals rounds back to back: three choices, a fast clock, and a streak to keep alive.
A word you have seen, three meanings, a few seconds on the clock. Getting one wrong never touches your progress.
A real sentence with the word blanked out; pick the word that completes it. Vocabulary proves itself in context.
Quiz the words you have glanced or your whole deck, set each kind's clock, and let rounds speak themselves as they arrive.
Every level of the official syllabus. Start where you are; let the widget carry you up.
Every level opens with a free preview · another word unlocks daily

Yes. The app is free on iOS: HSK 1 is free, every other level opens with a free preview, and another word unlocks daily. Lock&Learn+ is an optional upgrade that opens the whole syllabus at once, offered as a yearly plan or a one-time lifetime purchase.
Pinyin with full tone marks appears on the widget and everywhere in the app, so you can say each word out loud before the meaning is revealed. Pronunciation is never a guess.
There is no session to sit down for. The word waits on the screen you already look at dozens of times a day, you recall it before you tap, and the meaning arrives with a real example sentence. Learning happens in the seconds you were going to spend anyway.
In the way that matters, yes: every HSK word is a two-sided card, hanzi and pinyin on the front, meaning and a real sentence on the back. The difference is where the cards live: on your Lock Screen widget, one at a time, and in quiz mode. The full HSK word lists are also free to read on this site.
