Our verdict

LingoTheory drops you into role-played scenarios where you speak or type responses in Chinese, mixing in your native language when you get stuck, and get instant feedback when you make a mistake. Voice input understands both English and Chinese even within the same sentence, and daily practice is tracked to build a habit. The web version is free, but it doesn't teach pinyin or zhuyin directly, so plan to learn those separately.
