iPerf for Android

Used this to test wifi transfer rates. Works just as expected. Needs an option to prevent the app from transmitting on cellular data though as in just a few minutes it had used up 500MB (1/4 of my monthly data plan) as it continued transmitting after wifi dropped.

Installed Jperf 2.0.2 on Windows 10 laptop. Connected laptop to router and disabled WiFi. Use UDP option to avoid TCP window size issues. Measured 80Mbps downlink speed on phone using Xfiniti router.

Pinch me I must be dreaming. I can't believe how easy it is to run traffic with this app. Praise be!!!

Does what it needs to do, don't know why it requires one's location though...

Ugly text display that frequently drops parts of the output from the iperf program. App provides no help with setting up the options for iperf.

This is great app. I am using this for Throughput monitoring. I am trying to launch this app from ADB but I am getting only GUI not actually running iperf. Can you please help me to get commands to run from adb? Regards, Venkatesh

Doesn't work can't find wlan

Nice - it works! I can finally see how fast Wireless AC is on my phone... 450Mbit/s sounds good. I'd buy a pro version to support - especially if it had the new lollipop UK :) A list of last servers, as well as checkboxes for usual parameters would be nice.

Device ASUS tablet k016 sndroid lolipop

When traffic runs, If the device is kept in screen rotation, then if we toggle from portrait view to normal mode or vice versa....traffic stops. This is a major problem when I gotta run multiple devices in my IOT setup.

It all seems to work well except for the -r command which is supposed to allow bidirectional testing. It works in server mode but not client

Do what it has to do

Working as expected on i9505 + LP5.1.1

Does exactly what you'd expect it to do. My only complaint is that there's nowhere that mentions it's iperf2 (not iperf3); not difficult to figure out though.

Does what it needs to do, don't know why it requires one's location though...

How about adding some Excel/CSV export features?

works great on my nexus 7 tablet and moto g phone. Would like to see it also support iperf3. thanks.

- If the phone changes orientation, portrait or landscape, it clears the screen. - Sometimes the last line of the results don't show, which is the most important. Other than that, it's ok

you need to know iperf. I'm sure someone who cared to could put together a more noob friendly interface, but for my purposes it works like a charm (didn't work on Nexus Player, but I blame Google/Asus for that since the device was so utterly useless in every other way!)

There is no reason for this app to need access to the GPS. Why is this app tracking my location and why is there nothing about this anywhere in the description or on your website?? Rating will go higher when this permission requirement is explained. Thankfully there are apps to block these kinds of abuses like AppOps and Permission Denied.

Connects to server but produces no results

i cant launch it via the button or type `enter` key my environ is a samsung galaxy note N7102 with android 4.2

Thanks!

Trying to diagnose some WIFI issues with my router and this tool helped provides some concrete data to compare settings/routers.

Love this app on my phone But doenst work on the Eee Pad Transformer, WLAN issue with app =(

Nice tool, but a little bit more UI for the iperf features would be nice.

Its sucks i couldnt even get a signal it gave me something else #bad for androidd samsung

There is essentially no GUI for this app. If you happen to know the iperf command line arguments, many of them don't work. It cannot run as an iperf client, which is the mode I would most expect to use from the phone.

Don't have to cart a laptop about to assess WLANs, extremely useful. Thanks

Recomend having the man-page fro iperf open either in browser or via SSH for those who cant mke it work. -c for TCP test works just fine (ASUS TF101)

Will be great if you add easy accesible help or options button. Pre-defined commands or macros or something like last used iperf server will be usefull too. I'm boring ecery time entering simmilar information for quick speed test specialy on the field

Does what it needs to do, don't know why it requires one's location though...

I ran this on a slew of android devices and it almost never shows the results for the test. It shows titles for the columns where it should display the results but nothing underneath. I had to look at the server's output to see my results.

Console output is sometimes incomplete. The speeds are not always displayed.

But the "i" in "iperf" has nothing to do with the Apple naming convention and as such the case should follow normal rules, e.g. "Iperf for Android"

It would be nice if the ouput was easier to read.

Works well on my Samsung Galaxy Nexus running ICS. It tops out at ~20Mbps. Could be limitation of my wifi router because a laptop does the same. Only complaint is that when testing with -r option the second test stops after just 2 seconds. I've seen this happen on PCs as well, so no strikes against this app.

Not compatible with iperf3; returns null response. Menu::Preferences simply activates the "command line" entry instead of providing a preferences screen. Why is that option there?

If you know iPerf and use it regularly, you'll love this handy little app on your A/V system. I use it regularly to check out my HSI's performance. And hell, you get big nerd points when guests see the output running on your HDTV.

iperf is THE bandwith test tool there is and now there is a good android version. Very nice! Got 60Mbit on a SGS3 over 5.0Ghz. Client works, Server works, duplex test works, setting time duration works. Tested on Galaxy S2 and S3 and on a Asus Transformer all working. Only issue I encountered was a screen update issue that sometimes some text would fail to appear. Further then that, perfect.
