Popup Japanese Dictionary is a free offline Japanese-English dictionary app that helps you look up words by just copying the text from any screen. It is a perfect app for people who want to learn Japanese or improve their Japanese language skills. The app allows you to browse Japanese websites and forums on your favorite browser, be it Chrome, Firefox, or the default Android browser, and look up word meanings without leaving your browser screen. By alleviating the chore of switching apps to look up meanings, Popup Japanese Dictionary fits smoothly into the flow of reading.

The app is great for learning Japanese and improving JLPT vocabulary as it aids Japanese learners in consuming native Japanese material like Japanese forums and websites. Popup Japanese Dictionary is highly customizable, and the popup window can be resized, minimized, and made translucent. You can use it on demand and turn it 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.
