Very useful!
I'm trying to teach myself Chinese and having access to a dictionary while you do this is imperative, as it helps you to familiarise yourself better with the characters. But what I like the most about this app is the fact that if you use a Chinese keyboard this dictionary works not just as eng-ch, but also ch-eng. on the negative side, the sound rarely works and there appears to be a glitch with some words like 'huar' (painting) and 'lu' words.
