The app
Bopomofo Master turns the 37 symbols into five games. It is free on iOS and Android, works offline once downloaded, and tracks which symbols you personally get wrong so your practice concentrates where it is needed.
★ 4.6 from 20 ratings across the App Store and Google Play.
The five games
Symbol Match
Match each zhuyin symbol to its sound against the clock.
Character Master
Hear a word, pick the right Chinese character. Four difficulty tiers.
Sentence Typer
Build whole sentences on a real zhuyin keyboard.
Rocket Master
Answer correctly to refuel the rocket. Miss, and it drops.
Bopomofo Playroom
A bright, playful corner for young children — no timers, no scores.
What else is in there
Real recordings, not synthesis
Every symbol and over a thousand individual characters are recorded by native Taiwanese speakers.
It knows your weak spots
The app tracks accuracy per symbol and per character, so it can build drills from the ones you actually miss.
Streaks that survive a bad week
A streak-freeze mechanic means one missed day does not wipe out a month of work.
A leaderboard
Global rankings by total XP and by individual game, if that is what keeps you coming back.
Levels worth reaching
Seven levels from Zhuyin Apprentice to Bopomofo Elite, each with its own version of Bao, the app's bear.
Works offline
Audio and content are bundled, so a flight or a metro tunnel does not stop a session.
