You’re not starting from zero.
Your app shouldn’t either.
Most Mandarin apps are built for foreign language learners—they start with “hello” and teach tones as if the learner has never heard them. That’s not you.
Heritage learners carry years of Mandarin absorbed at home—bedtime stories, family dinners, overheard phone calls. They have a deep well of implicit knowledge—pronunciation, sentence rhythm, vocabulary they recognize but can’t read. What they need isn’t a beginner course. It’s a bridge from what they already know to reading, writing, and the confidence to keep using it.
MandarinBytes starts from that foundation. Intro cards say “You already say this—here’s how it looks,” not “Repeat after me.”

What the research says about heritage language development.
And what it means for your family.
Heritage language development follows a predictable pattern. Between ages 8 and 12, school demands increase, English becomes the dominant language of social life, and the heritage language needs active support to keep growing.
Linguist Silvina Montrul’s research shows that literacy is what anchors a heritage language past age 10. Maria Polinsky found that reading ability is the strongest predictor of long-term bilingual proficiency. And Lucy Tse’s work documents ages 8–12 as a turning point in how children relate to their heritage language.
The consistent finding: learners who build a foundation of ~500 characters during this window have the runway to reach reading independence—and reading is what anchors a heritage language long-term. And for those who are past it? The oral foundation doesn’t disappear—it just needs to be reactivated through structured reading practice.

Reclaim & deepen
The 8–12 window is critical—but it’s never too late. Teens and adults who grew up hearing Mandarin still carry that foundation, and structured practice can reactivate it.
Three things most apps get wrong.
Placement that respects what they know.
Heritage learners don’t fit neatly into “beginner” or “intermediate.” MandarinBytes uses adaptive placement that calibrates across listening, reading, and speaking—separately. Someone who understands spoken Mandarin but can’t read a single character gets the right challenge in both skills.
Practice that fits real life.
Sessions deliver meaningful practice in as little as five minutes. Mix of on-screen and printable worksheets, so families who limit screen time aren’t locked out of daily practice. No streak guilt. No punishment for missed days. Come back after a break and it feels like a fresh start—not a pile of overdue homework.
Traditional Chinese. Zhuyin and pinyin.
Both phonetic systems are supported. Zhuyin is the default because learners juggling English and Chinese can get tripped up when pinyin reuses the same letters with different sounds (Wang, Perfetti & Liu, 2005). Zhuyin’s unique symbols avoid that overlap. Prefer pinyin? Switch with a toggle.
How it works.
Enroll
Pick a curriculum, choose a starting point, and tell us what your child already knows. The app verifies and adjusts within a few sessions.
Daily practice
Open the app—the session is ready. Listening, reading, tones, sentences, and speaking, mixed and ordered by what’s due. Five minutes is enough.
Track progress
See per-skill progress for every character—listening, reading, speaking, and writing tracked independently. Honest data, not gamified numbers.
Built for kids. Grows with you into adulthood.
You already know some Mandarin. Maybe you grew up with it at home. Maybe you studied it in school, lived abroad, or married into a Mandarin-speaking family. Whatever the path, you have a foundation—and this app is designed to build on it, not start from scratch. Traditional Chinese, zhuyin and pinyin, iOS first.
Parents use it with young children learning their first characters. Teens use it on their own. Adults use it to build on a language they never quite finished learning—especially the reading.
If you’re starting from zero—no prior exposure to Mandarin from home, school, or life—this probably isn’t the right starting point, and we’d rather be honest about that.
