Does Anyone Have An Onvif iPhone App?

I'm trying to find an iPhone app that will talk directly to a camera using onvif. I've tried several and they either don't do Onvif or they require you install a program on your computer and then use your iPhone to connect to the computer. This is part of something I'm doing for initial camera set up. I have a small battery powered poe port and WAP that is working fine with my laptop but I want to strap my iPhone on my arm and set up the camera view. Any help appreciated.

Checkout Live Cams Pro. Will do a network search for cameras in their database and you can add cameras manually. Works very well.

We have been recommended to use ONVIF IP Camera Monitor

Never actually tried it though
