WORRIED YOUR CHILD'S CHINESE IS SLIPPING? Stringboard turns Chinese writing practice into something they actually want to do. Start with a free 7-day challenge. One short mission a day, no pinyin needed. A GAME, NOT ANOTHER WORKSHEET Each daily mission teaches 3-4 characters through a walkthrough, then a game where they shoot down falling characters by typing the correct stroke order. Just 10 minutes a day makes all the difference. NO PINYIN. NO MEMORIZATION. Stringboard's stroke-and-radical keyboard works the way kids already learn to write. If they can write it, they can type it. Even 4-year-olds pick it up in minutes. TYPING IS WRITING PRACTICE Every character is typed by selecting the right strokes and radicals in the right order, the same skill they need on paper. Real handwriting reinforcement is built into every tap. BUILT FOR BUSY FAMILIES No extra tutors, no printing worksheets, no scheduling around an already-packed week. Just open the app after dinner or on the MTR home. CANTONESE, MANDARIN, OR BOTH Toggle between Traditional, Simplified, and Cantonese characters with one tap. Whether your child speaks Cantonese at home, Mandarin at school, or both, we’re here to support you. REAL-TIME FEEDBACK = INDEPENDENT PRACTICE Live stroke and radical hints mean your child can practice on their own. You're not coaching homework at 10pm anymore. FREE TO START The 7-day challenge is free forever, no card required. When they're ready for more, one subscription unlocks every lesson pack: the full Hong Kong P1–P6 Chinese curriculum, with unlimited practice. The Stringboard keyboard works across every app on their phone, and stays free for life. Loving Stringboard? A quick review helps other families find us!
