XueCi Mandarin (学词, "learn words") helps you learn every HSK 1 to 6 word from the HSK 3.0 syllabus: 5,334 words, each with pinyin, a meaning and an example sentence with pinyin.

Why do the words you learned last week slip away? It's how you review them. XueCi is built on memory research: you review with gaps, not all at once. You're asked to recall, not just reread. And the app knows when it's time to stop and sleep.

A LITTLE EVERY DAY
Open the app and tap Start. You get the words you're about to forget, a few new ones, and practice on your weak spots. Reviews are scheduled with FSRS and adapt to how you remember. Pick a goal: a level by a date, the HSK exam, or no target at all. The app tells you if your target is too much. Short on time? There's a 2-minute practice.

RISE LIKE A CULTIVATOR
Your level is a cultivation realm, from 凡人 to 飞升. A realm only rises when your memory really gets stronger. Make your level's words solid until the 圆满 stage, then face the 雷劫: five strikes that test meaning, pinyin, listening, sentences and speed. Start with a 50-question placement test that adapts to your answers.

THE SEA OF CONSCIOUSNESS
Every word you've learned becomes one orb of light. The words you still remember shine brightest. Around it, five elements show which side of your learning is strong and which needs work.

CARDS THAT CHECK YOU
Swipe right for "I know it", left for "Don't know". Say you know it? Prove it first. Being sure but wrong brings the word back sooner.

SPEAK AND SEE
Say a word or an example sentence out loud and every hanzi turns green or red, so you see exactly which sound slipped. It uses your phone's own speech recognizer: no microphone permission, no recording kept. Choose how strict it is: Easy, Normal or Hard.

QUIZ AND HSK MOCK EXAM
Recognise meanings, recall hanzi, tones, listening, sentence gaps, typed pinyin and translation. Sentence questions give help by level, so beginners don't give up. The mock exam follows the HSK 3.0 paper, with a clock for each section and every question explained at the end.

REST IS PART OF LEARNING
When you start to tire, the app suggests a 5-minute break. Pick meditation days with no practice and no reminder, and your streak keeps going.

TONE COLOURS
Hanzi and pinyin are coloured by tone, so you remember the tone with the word.

FREE AND PRIVATE
No ads, no account, works offline. You can donate as a 护法 if you like, but nothing is ever locked. Your progress stays on your phone and moves to a new one with a backup code. Available in Indonesian, English, Thai and Vietnamese.
