Thought I could use it as a web cam

I rarely buy apps, but I bought this one hoping it would turn my iPhone 6S into a high quality camera that can stream to my computer. Unfortunately, its for MONITORING other cameras. So then I thought, Id at least try it out with my old web cam. I couldnt get it to work after over an hour of troubleshooting.
