The SWR4 Radio App is an Android application developed by Südwestrundfunk. It is a free multimedia program that allows you to listen to live broadcasts, special programs, news, comedy, music, and podcasts. You can also find detailed information about any song that is on air and send feedback directly to presenters.

The app includes a studio webcam, which allows you to watch presenters at work. Additionally, it provides detailed traffic information, a five-day weather forecast, and the latest news broadcast, all available at any time.

Although the app is free, it is important to note that listening to audio streams consumes a lot of data, which may generate additional costs depending on your mobile contract. Therefore, it is recommended to use a data flat rate to avoid additional costs.
