the dictionnary is good for people who have vocabulary and doesn't know complicated kanjis. The interface is easy, you can draw a kanji (the dictinnary doesn't care about the order of the strokes) and having its reading is really simple. First regret is that when you have the reading you can't get directly the translation. Now about the japanese-english dictionnary itself,it's complete,unless you're looking for a technical word. You can get directly from the english definition a japanese translation. About the english-japanese dictionnary. The number of words is kind of limited (31000words) compared to the japanese english dictionnary (64000 words).One regret, you can't get the translation or even the reading of a kanji (or a word) present in the japanese definition:( That's why I'm not recommending this dictionnary to beginners but for people who already knows the japanese language it's a really usefool tool.
