Faraday Test vs OONI Probe
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Faraday Test
Test the signal blocking capabilities of Faraday bags and enclosures. This utility app verifies complete signal transmission blockage for Wi-Fi and cellular signals, generating a detailed report of the results.
- Test Wi-Fi signal blocking
- Test cellular signal blocking
- Verify complete signal blockage
- Generate test reports
- Assess Faraday bag effectiveness

This app is designed to test the signal blocking strength of Mission Darkness faraday bags and enclosures. It allows the user to perform a test with wifi and cell signals to determine whether the faraday enclosure completely blocks signal transmission. A report is generated with the results.
OONI Probe
This app helps you detect internet censorship and surveillance systems by examining website and app blocking. It also measures your network's speed and performance, providing data that can serve as evidence of interference. All collected data is published openly to promote transparency.
- Examine website and app blocking
- Measure network speed and performance
- Detect censorship and surveillance systems
- Collect evidence of internet censorship
- Publish open network measurement data
- Free and open source software

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?

Verdict
The clearest difference is rating: OONI Probe at 4.5 against Faraday Test's 2.3. OONI Probe also leads on review sentiment (58% vs 29%) and update cadence (every 2 months vs every 10 months). Faraday Test's advantage is iOS requirement (12.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.
