Extremely handy app when I was studying in Japan. I didnt have a smart phone with data access but I had my iPhone with this app which acted as my electronic dictionary. I liked how it didnt need Internet to look up the words and it looked up words in English, all three Japanese alphabets (hiragana, katakana, and kanji), and Romanji. Also when kanji ever came up, there was a hiragana translation. I also liked the kanji look up via radicals, extremely easy to use and handy. One thing I am not thrilled about is the default frequently used search option that always seemed to be highlight as soon a new search is done, which is a minor annoyance for an overall amazing app.
