Replying to GoPro Lag?

Hey guys,
So I just ended up borrowing a GoPro from a friend, and downloaded the app onto my phone (its an iphone 4s if that helps) to see what I'm shooting. I'm going to have a friend a couple of some underwater shots, so its kind of essential that I can see where he is pointing the camera. Anyways, so I hooked up the wifi to my phone, and I'm noticing a ton of lag between where I point the camera, and what I see on my phone screen (like a 5 s delay at least). Any tips?

Thanks!
