### 5/5 — I love you Lily Ballard. Thank you. I finally got my first server connection all due to you.

### 5/5 — So useful

*2024-12-05, version 2.1.4*

I develop an iOS app that uses DNS-SD, so it’s not uncommon I want to check if my phone can see the host I’m looking for. I’ve been using this app for a year or so now to do these checks and I just love it. Thanks for the great tool.

### 4/5 — Super helpful, just needs iPad support

*2024-07-09, version 2.1.4*

Recently doing some debugging on my home network and found this app to be quite helpful. I'm quite comfortable with the shell, and did some debugging on my Mac, but only the phone (and iPad, but see below) had the problem I was troubleshooting so I needed to work there. The app does exactly what it says. It works well. It's got a minimal UI that uses default iOS controls but that's all it needs--anything else would be overwrought.

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!

### 5/5 — Thank Goodness

*2023-08-07, version 2.1.4*

After hours of troubleshooting why my home’s Thread network wasn’t working, this app told me what device was preventing it from resetting (it was a Roku). As long as you know what you’re looking for, this app is stupidly easy to figure out what’s going on with your network. Forever thankful for the Redditor that sent me here, I might actually learn how to read this now.

### 5/5 — The best out there

*2022-11-18, version 2.1.4*

Thank you very much for making this! It is an excellent tool which has saved me a lot of time troubleshooting mDNS issues.

### 4/5 — Good to have.

*2022-10-10, version 2.1.4*

Good to have.

### 5/5 — Excellent Utility Software

*2022-09-22, version 2.1.4*

This is a great little tool. It must have helped so many people. Developer - thank you !!!!

### 4/5 — Nice tool, subgroup support would be nice

*2022-07-27, version 2.1.4*

Currently this only searches top level services like _ipp._tcp but does not show subgroups like _universal._sub._ipp._tcp. That subgroup is particularily interesting as it is used by iOS to actually find printers for AirPrint, so a printer showing up in _ipp._tcp might not necessarily show up in the printer dialog.

### 5/5 — Magique !

*2022-01-19, version 2.1.4*

Une pépite cette app ! Juste vital pour analyser / debug Bonjour !

### 5/5 — Just works.

*2021-12-27, version 2.1.4*

I can’t complain; this app just works! I think it’s a great addition to what Lily started with Bonjour Browser on Mac a long time ago.
