It has OCR, it can parse text from your screen (screen reader) or clipboard, has male and female recorded voices, handwriting recognition, has about 20 different dictionaries including Chinese->Chinese and Cantonese, character etymology, their own flashcard system, the UI is extremely good. The search supports wildcards but is really fast. They are really attentive too, for example when their userbase pushed back against their flashcard system saying they use Anki, the devs added an extremely powerful and customisable Anki integration too.

To be honest I'm not the target audience for your app anyway, I'm not interested in yet another Edict-based dictionary - there are tons of them around and the quality is not good enough once you get to a certain level.
