ToneMaster: HSK Flashcards

Master Mandarin tones with colors.

Struggling to tell mǎ (horse) from mà (to scold)? ToneMaster turns HSK vocabulary into visual flashcards where every tone has its own color. See a character, hear the word, and instantly recognize its tone.

HOW IT WORKS
Each card shows the character, its pinyin with tone marks, and clear audio. Review the card, and ToneMaster schedules it again with spaced repetition, right before you would forget it. You remember more while studying less.

COMPLETE HSK 1-9 COVERAGE
• 10,693 unique words across all nine HSK levels
• 10,765 unique example sentences to learn words in context
• Pinyin with tone marks on every card
• Spaced repetition that adapts to what you forget

WHY COLOR-CODED TONES WORK
Each of the four tones — plus the neutral tone — is highlighted in its own color. Your eye learns the tone as you read, so correct pronunciation becomes automatic. Linking a color to a sound gives your brain an extra handle to hold on to — exactly what tones lack when you only ever read them on a page.

AUDIO YOU CAN TRUST
Every word and sentence includes clear audio generated by neural speech synthesis, so you always hear the right pronunciation. HSK 1 audio is built in; HSK 2-9 audio packs download on demand and then play offline.

FREE TO START, ONE PRICE FOREVER
HSK 1 is completely free. A single one-time purchase unlocks all of HSK 2-9. No subscription, ever.

PRIVATE BY DESIGN
No ads. No tracking. No account. No analytics. Just you and your flashcards — your progress stays on your device.

WHO IT'S FOR
• Complete beginners starting from zero with HSK 1
• Students preparing for an HSK exam at any level
• Learners who keep confusing similar-sounding tones


WHY TONES ARE SO TRICKY
In Mandarin, a single syllable can carry several meanings depending on its tone — the same sound spoken four ways means four different things. When you only read a tone on a page, your eyes have nothing to hold on to. ToneMaster fixes that by giving every tone a color you can recognize at a glance.

DAILY REVIEW
A few minutes a day is enough. ToneMaster includes a daily review of ten quick tone questions, plus minimal-pair drills that train your ear on tones that sound almost alike. Finish a set and you get a shareable result grid to track your progress day by day.
