One of the most important factors of any app is developer support and response from their users. This app has neither. No wonder there are so many bad reviews on here. BEAM2 Speakers are great but the app is clunky and poorly developed. Needs better support for android and more sound adjustments than just basic treble and base. Also needs an auto level control as some broadcasts are quieter than others so you constantly have to adjust the volume. Sonos needs a new developer IMHO.
