WhatsJap - 知らない英単語はその場で翻訳

If you find an English word you don't know while surfing the internet or reading an ebook, just copy it on the spot and it will be automatically translated and a pop-up will tell you the meaning.
You don't have to switch to the dictionary app every time.

The popup disappears after a while, but the translation result remains in the notification area, so if you miss it, you can check it later.

* On Android 10 or later, please pass the characters to this app by "Share" instead of "Copy".
* This app is an English-Japanese version of the multilingual app (Tranguage).
The operation is somewhat agile because it is exclusively for English and Japanese.
