Is there a difference between the iOS app and the Android app?

For the most part, the apps are work exactly the same way, although they are styled to fit with the look of each operating system. They have the same multi-room, multi-zone and stereo streaming features, and let you control all your Play-Fi products. Plus, the apps are interoperable, so you can use Play-Fi on iOS, Android, Kindle Fire, and Windows with the same set of speakers on the same home network.
There are the few differences between the apps:

• iOS Play-Fi product setup has one extra step.
• iOS supports iTunes playlists.
