Hanzi Master 3.5
Hanzi Master ("Hanzim") is an interactive visual dictionary for learning and seeing relationships between (simplified or traditional) Chinese characters, radicals, and compounds.
Suitable for all levels of Chinese learners. The 3.5 release brings improved integration of third-party dictionaries such as CeDict and HanDeDict. Handwriting recognition and several other platform-related improvements come to the Mac version, and the Linux version has been updated for better compatibility with recent distributions. Finally, a version for the iPad (called iHanzim) is now available.
