The app supports Japanese-Japanese, Japanese-English, English-Japanese and synonyms (japanese only). It's very easy to use. Just type in the word you want to look up and press search!
You can hear the pronunciation of a word by clicking the play button next to the search button.
To hear Japanese, you may have to download extra sound files.
There is also a "Kanji dictionary" function. Here, you can search for a kanji by handwriting.
To check stroke order of a kanji, select "Stroke order" from the menu.
You can also add words to the wordbook by tapping the ★ button and access them easily by opening the left side menu.
If you want to delete a word, just long-press on it.
