3/20/11: I cannot find this on the App Store now, maybe it's gone or has changed into something else.
- Includes "Say it!", apparently native speaker syllable-by-syllable pronunciation of entries, although I don't normally use that functionality.
- Search results do not start appearing as you type, unlike all other Chinese dictionary apps I have tested to date. This app may very well be a work in progress, so future updates may bring this capability.
- No in-app documentation.
