Common questions
What is the best English to Japanese translator app for Android?
Swift Translate translates English ↔ Japanese inside any app — chats, games, subtitles, and photos — with a floating bubble, and lets you reply in either language. It is rated 4.5★ from 83,000+ reviews with 10M+ downloads.
Can I translate Japanese WhatsApp messages?

Does English ↔ Japanese work offline?

Yes. Point the camera at Japanese text or import a photo or screenshot — the text is recognized and translated in about a second.
