The iOS app that you get from the AppStore runs on an iPhone. You also need to download and install the Netflix Controller app available for Mac and Windows. It must be running on the computer on which you watch Netflix and is needed for the Netlix Remote iOS app to work. If the device on which you watch Netflix does not run a Mac OS X or a Windows operating system, this app will not work for you. For example, if you want to watch Netflix on an iPad, Android tablet, Windows Surface RT, Xbox, Wii console, or Linux this remote will not work.
