How to connect iPhone 5s to SmartFace?

I've just installed smartface version 4.3.0

I connected my iPhone 5S to the laptop using USB cable.

I launched Smartface App Studio, clicked on Device Emulator from toolbar. Clicked on Yes button when User Account dialog appears. Progress Dialog appears, it says: "Searchign for devices... Devices found: Simon's iPhone

Keep calm ;) You need to download Smartface in action from app store and then please try again.

Same issue again? Please refer to Troubleshooting document!"

I downloaded the app on my iPhone and launched, what haven't I done?
