About this app

Share 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 sharing text. Upon sharing of a word with Popup Japanese Dictionary, a small window will float on the screen, showing the definition(s) of the selected word.

Note: Due to changes in Android's clipboard functionality, Popup Japanese Dictionary must now be activated by sharing a word with the app, instead of by copying a word to the clipboard.

KEY BENEFITS: Dictionary lookups made convenient!
• Free offline Japanese-English dictionary
• Displays Japanese word meanings upon sharing of the word, from any screen
• Word definitions will appear in a small translucent popup window, which floats on top of the screen
• Customizable appearance - Popup window can be resized, minimized and made translucent
• Use it on demand - Minimize the popup window when you want to conserve screen estate; it will be automatically restored the next time you share 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.


USAGE EXAMPLES
• 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
• Translate emails by looking up unfamiliar Japanese words using Popup Japanese Dictionary
• Aids Japanese learners in consuming native Japanese material like Japanese forums and websites. Helps in learning JLPT vocabulary.
• Basically, from any app that allows you to select and share words, Popup Japanese Dictionary can spring to action and display the definition in a window overlay on top of your screen

Exactly what I needed, I read reviews saying try KAKU app instead, so wasted time installing that app and it was slow and clunky and difficult to use as reviews of that app say. Popup Japanese is exactly what it says it is. Smooth, fast, simple and easy to use and doesnt take up a ton of space or slow down or freeze (like KAKU) normal operations. Finally I can read Japanese news sites without the hassle and time of constantly switching btw apps to look up kanji. Thank you

It's like the Rikaikun of Android but unforunately it's a bit too basic: it popups even when you might not want it to. e.g. you're copying an English word or a phone number or URL, etc.. Also you can't edit the word being looked-up. This is a problem when copying from messaging apps like Messenger and Line which only allow copying of the entire text message so obviously it's not going to find it in the dictionary. Would be nice if it did a multi-word look-up like Takoboto and also allowed you to edit the looked-up text. If the above was fixed, I would give 5 stars.

I really love this app for letting me check words without leaving the browser page. Unfortunately this version doesn't work with my phone now which is on Android 10. I'm really looking for an update that will let me use this app again. Popup is essential for smooth reading experience in Japanese, so would definitely recommend.
