There are several Sonos apps available on the Apple AppStore - some are grossly out-dated - and the manual is not clear as to which app is appropriate for the Move. I struggled with the wrong app until I dug deeper at the AppStore. For the Move (and others?), use the simply named "Sonos" app.
Pros: Airplay compatible, Expandable, Superior Sound, Wireless
It was super easy to set up and add to my current Sono system. Waited a while to add another speaker. I now can take my music out on my deck when I want. Very happy and my friends love listening to my smooth jams.
