Doesn’t show a live graph. Sometimes doesn’t show a graph at the end either, just a bunch of difficult to read JSON. Doesn’t show any results while running. Only after it completes. Save your money and look elsewhere.

Update: I am perfectly calm. I’m just disappointed in myself after spending money on this app and then being insulted by the developer. I wish I had read the other reviews first. I did, in fact, set the interval option. This app appears to be a minimal port of a free command line utility which, I might add, has a much more robust set of options and instructions in its man page. The only value added by this developer would be the graph, if it worked. At best, I can get it to show 1 to 3 data points before wiping the screen and starting over. At worst the graph doesn’t display and the screen is filled with JSON output. Very inconsistent. If I could give zero stars for the rating, I would.

Developer Response ,

Dear Sir/Madam, thanks for your feedback, please calm down, what you described is very unlikely the problem of the tool but problems of the Wi-Fi RF environment, if you want, please contact and we can further discuss the possible reason or any kind of solution that could be worked out, sincerely, thanks and have a good day!

Doesn't work

App doesn't work on iOS 6, iPad mini, even though it is supported. I have been ripped off.
App simply crashes with no error message whenever launching either as client or server.

More Documentation in App

Needed iperf quickly to troubleshoot a problem and bought this. It continually failed while testing with jperf for windows and gave little reason why. Maybe I didn't set something correctly, but for $4 I would expect a little more documentation or at least some screen shots for setup. Maybe I missed that info somewhere on here. If I did and I find it then I will upgrade my rating.
