Hows it work?

I dont understand how this app works. Auto open instructions arent very intuitive. Im new to iPhone so this issue is probably, partially, operator error. The app needs better instructions on how to use this app to auto open links from email into apps. Im not blaming this app for that piss poor iOS issue but I havent been able to open a subtle link in an app yet. Help please!
