Super helpful, just needs iPad support
The only thing that's missing is I'd love to have a proper iPad version. It doesn't need to be anything special, all it needs is an iPad-size UI. The stock iPhone app scaling is pretty unpleasant to use, especially in landscape--I've got an iPad Pro with a keyboard attached all the time, so I never use it in portrait.
All that said, though, to reiterate, this is a great app on the iPhone which makes troubleshooting Bonjour stuff a lot easier than it would be otherwise!
