About Netalyzr
Netalyzr for Android is the free (and ad-free) mobile version of the popular network debugging tool Netalyzr. It analyzes a wide range of properties of your Internet connection that you should care about, including blocking of important services, HTTP caching behavior and proxy correctness, your DNS server's resilience to abuse, NAT detection, and (optionally) latency & bandwidth measurements. It reports its findings in a detailed report that highlights any identified problems. You can check out an example report from a real network at http://netalyzr.icsi.berkeley.edu/restore/id=example-session in order to get a better idea of our tests.
Netalyzr is not only a debugging tool — it is also the foundation of a comprehensive measurement study compiling a survey of the health of the Internet's edge. Netalyzr is brought to you by a team of researchers at the International Computer Science Institute in Berkeley, California. By running Netalyzr and helping us spread the word you are contributing to the quality of our study — thank you!
ANDROID PERMISSIONS:
Netalyzr requires network-related permissions, location information (whose collection you can disable), and the ability to close other apps (to increase test accuracy; you can disable this feature as well). SDCard access is required to store the results of the tests. We do not have any interest on your personal data but if you enable location information, you will help us to improve the accuracy of the results!
ROOT PERMISSIONS:
If your device is rooted, we will ask you for permission to use root privileges in order to conduct IP traceroutes from the device. If your handset is not rooted or if you do not grant root privileges to the app, the traceroute test is skipped.
You can find more information on the Netalyzr on its website at http://www.netalyzr.icsi.berkeley.edu, and use our Google+ Community for discussion, questions, suggestions, and feedback:

Need more thought on Things and make it run faster and give an option to go more in depth. For when it's does in depth it always give bad net on every network.

This app has some great and unique features, but it feels like the design was done pre- Material and the Support/Design libraries. I'm confident this app could be sped up and made more responsive.

I clicked install and it said the download would appear shortly. then the download didn't start and the website is insisting the product is already installed and refuses to "reinstall" it. it is nowhere to be found on my computer and does not want to let me reinstall it. guess this product just doesn't want to be used

Servers can not be reached?!! I waited five mins to see that! Looks like it has amazing potential, but if you're gonna take the time to develop an app, you've gotta take the time and make server uptime a priority!

Very thorough, but I would like more instruction on how to remove problems;yet, the most in- depth screening, including the Clean Master apps. But I still use them too.

After 70 minutes, all the tests appear to have run through, but I cannot see any of the data. Netalyzr does not complete step 121/121. "Gathering results for fetchAkamizedIcon." It looks like the app needs much more error catching. It should still let me see the results for the steps that do complete.

Love it, could be better in some ways, but it helped me prove I had lag on my end when I had nearly 500ms unload latency before. Keep adding more to this app guys!

I've tried twice to diagnose my network and there's been an ongoing issue where the app cannot connect to your servers. Other reviews state this too, what's going on?

Time after time it runs all the tests and then fails to show results instead reports "everything is OK but we cannot connect to our servers" poor app or development!

It takes so long that my screen turns off and usually results in an error that it couldn't upload. Gives me a notification several times a day. Asks the survey questions multiple times if it loses focus. More hassle than it is worth these days.

Useful and extensive app, but if your cellphone's data plan is limited, DO CERTIFY THE CELLPHONE IS CONNECTED TO THE WI-FI BEFORE RUNNING THE TEST, otherwise you're gonna break through the data limit in no time. I know this was my fault, but, in my opinion at least, this kind of check-ups an utility app should do by itself.

Upload speed test tends to hang on one location I manage/monitor that has double NAT. Otherwise, helpful to verify my firewall port blocking is functioning as expected, and to help diagnose network anomalies.

It takes 5 minutes to step through all of the 120+ tests, then just as it finishes it states it can't connect to netalyzr servers and to try again later, without displaying any of the results. Will try for a third day tomorrow!
