Hanzi Master Deluxe 3.5

Hanzi Master (Hanzim) is an interactive visual dictionary for learning and seeing relationships between Chinese characters, radicals, and compounds.

All characters with a given radical, phonetic component, or pronunciation can be displayed, together with all words containing a character, with English meanings. Either simplified or traditional characters can be used. Any Chinese text can be annotated with mouse-over definitions. The application can be set to display subsets of characters based on usage frequency, making it suitable for all levels of Chinese learners.
The 3.4 release brings improvements to flashcard presentation, including a full-screen mode and the ability to mark known cards. You can now also download vocabulary lists from an online library. Bug fixes were also made.

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. There is a new tutorial for lists and flash cards. Finally, a version for the iPad (called iHanzim) is now available.
