When you need to learn how a Chinese character is written, the answer should be easy to find. Open Baba Chinese Writing and hold the microphone button. Ask in Chinese, or switch to English and say something like β€œHow do I write sunny in Chinese?” Release the button to see the Chinese result with pinyin, writing grids, and animated stroke order. Baba Chinese Writing keeps one everyday task simple: ask for a character and clearly see how it is written. KEY FEATURES β€’ Ask by voice in Chinese or English Chinese mode understands Chinese questions. English mode extracts the word or short phrase you ask about and uses Apple Translation to produce a common Simplified Chinese result. β€’ Pinyin and writing grids Each character appears on its own card with tone-marked pinyin and a clear grid for understanding structure and proportions. β€’ Animated stroke order Watch the character written one stroke at a time in the correct order, with progress shown during playback. β€’ Tap to replay Tap any character card whenever you want to watch its writing animation again. β€’ Learn up to six characters at once Study a single character or a short word. Card sizes and layouts adapt automatically to the number of results. β€’ Designed for iPhone and iPad The practice area adapts to portrait, landscape, and different screen sizes. β€’ Chinese and English interface The app follows your device language on first launch, and you can switch at any time from Help. Chinese mode recognizes Chinese questions; English mode recognizes English questions and returns Chinese writing results. β€’ Built-in learning resources Pinyin and stroke-animation resources are included with the app, so no online character library needs to be downloaded during use. β€’ Focused and uncluttered No account, no social features, and no unnecessary steps between your question and the writing animation. TIP Speech recognition and Apple Translation availability may depend on system support, downloaded language resources, and network conditions. The first use of English mode may require Apple’s English and Simplified Chinese translation resources.
