The much-awaited update has now been released and is available in Google Play Store, Huawei AppGallery (except for China Mainland). Besides the promised RTL-SDR V4 integration, the “Hack-RF” receiver is now supported, as well as a new function to select the audio output device and other improvements.

Johannes von Weyssenhoff, Starwaves CEO, sees this as “a further step towards great affordability of DRM receivers, as the RTL-SDR V4 is one of the most cost-efficient receiving devices for DRM in the AM Band. The barrier of 50$ has been now broken!”
