Think I figured it out.

Okay I think I figure out why no one has gotten this app to work. From my understanding, you must download the app "Hunting Call" from KSolutions first for $2.99 from the App Store to be used in conjunction with the "Hunting Call Remote" which is also from KSolutions and used in conjunction together for this app to work. "Hunting Call Remote is just an add on for that app.
