About this app
■ The only subtitles that float over ANY app Turn Japanese / Korean / English speech in any video app into live subtitles, floating in a Picture-in-Picture window on top — works with any player. Other translators can only screen-record; only Fanshu floats across apps. ■ Fully on-device AI — privacy first Speech recognition and translation run 100% on your phone. Audio is never uploaded, never sent online, never stored. ■ Many languages, any direction Chinese / Japanese / English / Korean / French / German / Spanish / Italian / Portuguese. UI in English, Japanese, Korean, Simplified & Traditional Chinese. ■ Two modes · Screen audio: translate sound from other video apps · Microphone: translate speech around you ■ One-time purchase, yours forever A daily free allowance to try; buy once for unlimited use. No subscription, no ads. Note: the first time you use a language it downloads its on-device model (one-time online), then works fully offline.
