About this app

Are websites and social media apps blocked? Is your network unusually slow? Run OONI Probe to find out!

With this app, you will examine the blocking of websites and instant messaging apps, measure your network's speed and performance, and check whether systems that could be responsible for censorship and surveillance are in your network.

OONI Probe is developed by the Open Observatory of Network Interference (OONI), a free software project (under The Tor Project) that aims to uncover internet censorship around the world.

Since 2012, OONI’s global community has collected millions of network measurements from more than 200 countries, shedding light on multiple cases of network interference.

Collect evidence of internet censorship
You can check whether and how websites and instant messaging apps are blocked. The network measurement data you will collect may serve as evidence of internet censorship.

Detect systems responsible for censorship and surveillance
OONI Probe tests are also designed to uncover the presence of systems (middleboxes) that could be responsible for censorship and surveillance.

Measure the speed and performance of your network
You can measure the speed and performance of your network by running OONI's implementation of the Network Diagnostic Test (NDT). You can also measure video streaming performance with the Dynamic Adaptive Streaming over HTTP (DASH) test.

Open data
OONI publishes network measurement data because open data allows third parties to verify OONI findings, conduct independent studies, and answer other research questions. Openly publishing OONI data also helps increase transparency of internet censorship around the world. You can explore and download OONI data here: https://ooni.io/data/

Free software
All OONI Probe tests (including our NDT and DASH implementations), are based on free and open source software. You can find OONI software projects on GitHub: https://github.com/ooni. Curious to learn how OONI Probe tests work? Learn more: https://ooni.io/nettest/

When wars & global events, boost institutionalized directives & inobjective info (from different sides!), U might want 2 investigate what officials, providers & allmighty corporations r keeping from ur ears & eyes! - ALL MEDIA & PUBLISHERS should not cut critical view & freedom of speech! This tool, allows U 2 test and share how free services can operate within the net(s) you are using. Resistance isn't futile! PS: It would be wise, if urls for website testing could b saved in the app!

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 its a battery waster and data waster; They have a piss, poor development team; if this is the kind of service, they deliver.

I'm not saying it's a good thing or a bad thing, but there is too many weird connections to my device through this app.
