About
Caption Radio turns any live internet radio broadcast into readable captions - and translates them into 19 languages - entirely on your iPhone.
Tune into 30,000+ live stations from every country. Browse by map, search by genre, language, or country, and save favorites. As the station plays, captions appear in sub-second sync, refining word-by-word as the on-device model listens. Switch the translation language anytime without missing a beat.
Everything runs on-device. No accounts. No sign-in. No audio ever leaves your iPhone.
