Ein erneutes Öffen zeigte auch die richtigen Werte an. Wenn ich aber auf „Review an start client“ klicke, sehe ich ganz andere Werte. Für Port steht da 0 und für Client iperf.scottlinux.com. Mit dieser Konfiguration läuft natürlich nichts. Aber es gibt keine Möglichkeit, sie zu ändern ### 2/5 — Colours and option setup is horrendous *2021-03-14* The light blue line across the top when in the settings has slightly different colour blue writing on it. Nightmare to find what to tap on. Every setting is in a new window. Why? Not necessary, just make the setting available on the setting page. Not easy to use. ### 3/5 — Server not working. But when I reinstalled it, it worked fine. *2020-09-21* Cannot use server mode. But when l re install again in accordance with developer’s comment, it works fine. Thanks **Developer response:** Please delete and re-install the App, make sure the device's disk is not full, thanks! ### 1/5 — Rubbish *2019-05-27* 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 asolutioncontact@gmail.com 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! ### 4/5 — Works *2017-07-18* Was crashing but worked after reinstall **Developer response:** Please send email to asolutioncontact@gmail.com to get help as claimed on VERY top of our support page, we will be very happy to help you because it will help to improve the quality if it is a real bug and meanwhile it helps to resolve the problem you have encountered with. The problem you reported here most likely related with an unsuccessful installation or update of the app, please try to reinstall (uninstall and then install again) the App. We would appreciate if you can delete this meaningless message as it will NOT benefit anyone. ### 1/5 — Useless!!! *2016-12-31* Crashes constantly. It's nice you can edit parameters, but the user interface is awful. Don't waste your money like I did ! ### 3/5 — Na ja *2016-07-13* Zeigt bei meinem 16 Mbit/s 100 Mbit/s Durchsatz an. **Developer response:** The poor WiFi signal will dramatically affect iPerf performance test, you will tune up -b option in order to get the highest throughput of your WLAN, please view my blog (http://aosoft-support.blogspot.ca/) for further information. ### 2/5 — Meh *2016-07-08* The GUI is ugly, and the app crashes if the server refuses the connection. Also this is a free tool, a port should not cost $4 ### 5/5 — Works well *2016-03-02* This app works well with the iPerf 3 server for Windows. ### 4/5 — This app did what I needed *2015-10-25* It worked for me. I ran it on an iPad 4th gen running IOS9 connecting to an iPerf3 server. I used it about 15 times, and 14/15 times it worked perfectly. One time it spit out errors, but restarting the app fixed it. The interface is fine if you already know iPerf. ## Frequently asked questions about iPerf3 Performance Test Tool ### What is iPerf3 Performance Test Tool? iPerf3 Performance Test Tool is an iOS application designed to measure wireless network bandwidth and throughput on your local network.
