So I found out after hours of troubleshooting that this app crashes and cant work on an isolated network (using apples own airport modems) you simply MUST have an active internet connection or the app refuses to function.
Its also extremely annoying that it has to fully reboot everytime you open it....other apps stopped doing that 5 years ago.
Other than that it works great and does what its supposed to.
