Karo Radio
Free focus music, without another account.
Choose Deep Focus, Gentle Flow or Unwind, then layer rain, café or forest ambience. Karo prepares the next tune in advance so the radio keeps moving.

Music designed to stay out of the way
Karo Radio uses instrumental productivity tunes selected for longer work sessions. There are no ads, lyrics or external music account requirements.
Build the soundscape you need
Music and ambience have independent volume controls. Keep a tune low beneath rain, use café sound on its own, or work in quiet.
Fast, continuous playback
Karo warms the selected track and the next track from its public audio service, while local fallback audio remains available if the network has a problem.
