FEATURES

• Favorites — star the channels you follow most for quick access.
• Background playback — keep listening with the screen locked, and control playback from the lock screen and Control Center.

ABOUT THE AUDIO

Scanrad.io plays lawful, over-the-air reception of public radio transmissions. Because it's real, live radio, audio is unfiltered and a channel is only active when something is actually being transmitted — quiet channels simply mean no one is talking at that moment.

Listening to these public transmissions is legal in the United States. Availability and legality of radio reception varies by region; please use the app in accordance with your local laws.
