Amazing tool for immersing & learning the language

Thanks for making this app! I use it to translate light novels/ songs/ tweets and whatever else I browse in Japanese to learn. As someone who doesn’t have a laptop, this app lets me immerse into Japanese material when I’m not at my desktop and it’s perfect for it. The only thing that could make it better is integration with Anki in order to be able to easily make cards from the new words I encounter. I know its already possible by copying and pasting the information but auto-filling anki fields with the word/reading/definition would be cool (however I am not sure how possible that is to implement on iOS)

I’ve wanted rikaikun on iOS for so long. When they announced safari extensions it was the first thing that came to mind. I never would have expected it to be this polished on day 1, though! Please consider adding EPWING importing 🙏

Long time yomichan user but always despaired I could only use it on my desktop. Friend let me know about this and it is a huuuuge help. Every Japanese learner needs this.
