ウィズダム英和・和英辞‪典‬ 4+

I purchased this with the full intention of using it bidirectionally (english->japanese->english), but unless you're very familiar with kanji, you're not going to know how to pronounce the words it shows you when doing the english -> japanese look-up. It only shows the kanji for it, not the individual hiragana. It's pretty useful when going from Japanese to English since you already have to know how to pronounce the word to look it up, and you can just focus on the english meaning it displays. It does have audio samples, but surprisingly, they're only for English words. (At least that I've seen). Overall, I think they could've done more to help aid English speakers... perhaps with an upgrade.

It’s just OK, doesn’t have some relatively common words like 遷移。I wouldn’t recommend for business or professional use.

This is a great English-Japanese Japanese-English dictionary for anyone who is learning Kanji and comfortable reading in Hiragana/Katakana. While there is no furigana in the Japanese entries (as some have complained), the jump function (activated by holding down your finger over a world) will look up the word and give you the pronunciation and English translation. This is ideal for an intermediate/advanced student of Japanese because while readings and definitions are available, they are not presented in a way that disturbs you from reading Japanese in its natural form. This is also helpful to see how looked-up words get translated back. I do not understand reviews complaining this product requires knowledge of all kanji. That is certainly not the case. The dictionary has helpful example sentences in Japanese and English which greatly enhance it as a study tool. While it is not perhaps the most comprehensive dictionary available, it is by far the best dictionary I have seen available for the iPhone both in terms of content and ease of use.
