iPhone doesn't seem compatible – Google Cardboard Review

Well, I attempted to use this VR and I can get to the home page but the screen of the VR will not respond to my prompt, which means I can not get to the next screen. After more research, it was explained that this VR isn't compatible with iPhones, yet the box says otherwise. IDK...I have an iPhone 7 plus, so not sure if that's the issue and regular iPhones work with it. Frustrated.
