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.
To perform its tests, 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). If your device is rooted, we will ask you for permission to use root privileges in order to conduct IP traceroutes from the device.
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!
