Not Sonos- just another scam app that can play on 1 Sonos speaker.
Was looking for something to help bridge legacy S1 with S2 system. All these apps seem to do is spam for subscription $. You can only connect to 1 speaker at a time, then use a clunky UI to play songs. If you only have 1 speaker & want to spend excess time setting things up, maybe these apps are fine. Otherwise, use the real Sonos app & let it do its magic.
