Comments on OONI Probe for Android

★★★★★ David Crahmaliuc · Aug 2, 2024

OONI Probe is a fantastic tool! It's a free and open-source software that allows you to test the blocking of websites and detect censorship in your network. OONI Probe is designed to help you identify whether certain websites or online services are being blocked or throttled by your internet service provider (ISP) or government. By running OONI Probe, you can get a better understanding of your internet freedom and identify any potential censorship or restrictions in your area.

I don't know where these developers think that it's okay to take over my phone for an hour and thirty minutes The amount of time it takes for these scans to run when it only took fifteen minutes before is insane and unacceptable I didn't sign up for a virus scanner If anybody uses this app, I recommend you disable it until you go to sleep it's a battery waster and data waster; They have a piss, poor development team; if this is the kind of service, they deliver.

Since the last update (May 2024), no longer works in Android 7. Always crashes when running tests, any kind of tests.

First you have to go to their website to see your phone's scan results and then nothing is broken down to give you any information, unless you understand a graph of lines that tell you nothing

Unfortunately it does not test torrent, file sharing websites, IPTV etc. which are mostly the targets of blocking Corp-govt elites. It only probes for basic websites, not the ones that are really targeted.

★★☆☆☆ Bluezebra2 · Jul 24, 2023

For an app run by the Onion network, im surprised and disappointed that the app had trackers. And I am especially disappointed that one of the tracker is Facebook (meta). I mean all the stats from the probe are (unless opted out) automatically sent to you. So what's up with trackers?!
