Wordbrush: Learn Chinese HSK

Mandarin flashcards with audio

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Free, every word of it. All 2,199 HSK 1-3 words, clear HD Mandarin audio, characters decoded, and a hint that draws the real brushstroke. No locks, no ads, no accounts. Free, in full. Drill every HSK 1, 2, and 3 word into long-term memory, all 2,199 of them, in frequency order. Natural HD audio for every word and every example sentence, every character decoded by its radicals, scheduled by FSRS spaced repetition. No accounts. No ads. No streak guilt. Ten minutes a day. Open it, do today's session, close it. Come back tomorrow. The science wins arguments. Wordbrush uses FSRS, the modern free spaced repetition scheduler that powers Anki. Cards reappear on the precise day your brain is about to forget them, not before, not after. Failed cards loop back in minutes; mastered cards stretch out for months. A Chinese flashcard without sound is half broken. Every word is paired with studio-quality audio rendered by Google's Chirp 3 HD voices. Tones, prosody, register, all there. Every word also gets a hand-curated example sentence in a second voice for context. Show, don't tell. Each character is broken down into its radicals, the meaningful sub-components, with pinyin, name, and a one-line note on what they signify. The water radical 氵, the heart radical 心, the woman radical 女. You stop memorizing characters one stroke at a time and start seeing how they're built. The HSK levels unlock in order. You start with HSK 1. Once you have introduced every HSK 1 word, HSK 2 unlocks. Then HSK 3. The Statistics screen shows your progress through each level. The scheduler keeps you focused on what's actually in front of you, not what comes next. What's inside: • 2,199 words, every HSK 1-3 word, in frequency order • 4,398 audio recordings (one per word, one per example sentence) • Five card formats: recognition, listening, and production for every word, plus sentence-building and character-tracing cards • Hand-curated example sentences for every word • Character breakdowns by radical, with etymology and position • Bottom-up unlock so you finish HSK 1 before HSK 2 starts • A simple home page: a calendar showing your activity, today's count, and a single "begin" button • iPhone and iPad • Full VoiceOver, Dynamic Type, and high-contrast support What it costs: • Nothing. Wordbrush is free, in full. • Nothing is locked. No trial to run out, no locked words, no tiers, no add-ons, no ads. What's not inside: • No accounts. All your data lives on this device. • No advertisements. • No notifications nagging you back. • No streak shame. Skip a day, the app waits patiently. • No leaderboards. The only person you're competing with is yesterday's you. Open the app. Today's session is already cued up. Read or listen to the front of each card, mentally answer, then tap to reveal. Rate it strictly, Again if you missed it, Easy if it was instant. Wordbrush handles the rest. Built for: • Adult learners who already know other resources exist for grammar and conversation, and want a tool that does one thing well • Anyone who's bounced off gamified language apps and wants something that respects their time • People who appreciate restrained, calligraphic design over neon mascots Wordbrush is finished. Open it, do today's session, close it. Come back tomorrow. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy policy: https://wordbrushchinese.com/privacy

Lighter days, clearer first steps. A new "reviews only today" link under begin starts a session with no new words, just the ones due. For the days you want to consolidate rather than grow. Already know a word? Rate it easy the first time you see it and it leaves without using up your daily new words. The first-run tour says so, and so does the rating bar on your first sessions. The first listen card in the tour now tells you what to do, and a round of fixes to word parts, glosses and example pinyin lands with this update. Also fixed: the day's target no longer shrinks as you study. One Short a day: youtube.com/@wordbrush.
