About this app

Copy any Japanese word to look up its meaning, without leaving your current screen! Popup Japanese Dictionary is an offline Japanese dictionary app that lets you look up words just by copying text. Upon copying a word, a small window will float on the screen, showing the definition(s) of the selected word.


KEY BENEFITS: Dictionary lookups made convenient!
• Free offline Japanese-English dictionary
• Displays Japanese word meanings upon copying of the word, from any screen
• Word definitions will appear in a small translucent popup window, which floats on top of the screen
• Customisable appearance - Popup window can be resized, minimised and made translucent
• Use it on demand - Turn Popup Japanese Dictionary on when you want it to listen for copied words, and easily turn it off from the notification bar when you wish to disable the dictionary. Minimise the popup window when you want to conserve screen estate; it will be automatically restored the next time you copy a word.
• Great for learning Japanese and improving JLPT vocabulary - alleviates the chore of switching apps to look up meanings, as Popup Japanese Dictionary fits smoothly into the flow of reading.
