Use Network Speed Tester to measure the actual transfer speed of your local wifi or wired network. A graph helps you see changes in realtime. Optimize your wifi network by moving or placing your wifi router until you reach the best results.

Make sure to also download the free iOS Client App for even simpler speed tests between Mac and your iPhone/iPad or the Apple TV.

Example Uses
- Verify your network components (swiches, router) to find bottlenecks in your wired network
- Optimize the placement of your wifi router, try different locations until you get the best network performance
- Measure impact of wifi range extenders
- Find the best spot for watching streaming movies in your home

- Accurate performance measuring of your network using client-server technology
- Get actual realworld network throughput
- Graphical visualization
- Find test servers automatically via Bonjour services
- Export data to tab text format
- Share results

To make a proper measurement, you need to have either two Macs in your network, or one Mac and an iOS/tvOS device. (iPad, iPhone, iPod Touch, Apple TV are supported) The Mac will act as a server, the other device as the client for visualizing the results.

Excellent specific utility

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.


Very Simply Put

The app did exactly what I wanted it to do on the first try. I started a screen share with my server from my MacBook and grabbed the app from the Purchases tab. Launched it on the MacBook, launched it on the server, selected my MacBook’s name and boom, 91. Thanks.


Pretty worthless for testing servers

Seems to be no way to enter user name and password for a secure server connection you want to test. What’s the point of the software if you can’t connect to anything external?

Developer Response

This app is not for testing external servers! It is for point-to-point network testing, usually within a local wifi or wired network. An iOS client is coming soon to make testing even easier.
