Yes, Stream Master is not officially supported on iPad — it is a Windows application. For multi—streaming directly from the iPad, there is a great alternative - SplitCam. It's free, designed specifically for iPad, and allows you to stream simultaneously to multiple platforms (Twitch, YouTube, Facebook, and others via RTMP). The interface is simple, the broadcast quality is configurable. If you need more platforms, try OneStream Live (paid, but powerful)
