Not bad but the app crashes frequently on macOS Monterey 12.5.1.

Big video files taking forever to download from your networked storage? Not keeping up with the famous-for-being-famous because the gossip websites won’t load before the news is olds? If so, and you’re wondering where the fault lies, you COULD check your internet speed. You COULD clean your computer. AND – you could run a test of your wifi network’s speed and see whether you need to buy a new router…or maybe just relocate your current one. Do you have two devices you can connect to your network? Like a computer and a smartphone? Of course you do! So with this app and the companion app for your phone, soon you’ll know whether the fault, Dear Brutus, lies in your ISP or in your home. You’ll need free services to check the speed of your internet connection, but this app will tell you how well your devices communicate with the gatekeeper to all that is good in the world, your home or office wifi network. Easy to use, quick, with good quantitative results. An excellent utility and well worth the price if you’re trying to diagnose a case of internetus delinquens.

This is a great tool for measuring network throughput and helping to figure out transmission problems. I had a bad cable termination somewhere in a transmission chain and this helped me find it. I was also able to use this to move around my wireless AP to get good signal. I’d love to also see packet loss and latency in the graph in the future since those factors also change.

I was really hopeful this could help me diagnose some issues with my router placement. But when I start the test from the client app on my phone, it receives data for only a few seconds before the server app on my computer crashes and the test stops. Bummed that I'm out $4 and more bummed that I can't get the data I was hoping for.
