OONI Probe vs Wehe
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
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?

Wehe
This app tests your network to detect if your provider is restricting or prioritizing traffic for specific applications or ports. By running these tests, you contribute to an IRB-approved research project aimed at identifying potential net neutrality violations. All collected data is deidentified and published as open data to support research.
- Network traffic analysis
- Detects traffic prioritization
- Identifies network restrictions
- Contributes to net neutrality research
- Deidentified data collection

Wehe is an app that runs tests against your network and analyzes the results to let you know if your network provider is restricting or prioritizing traffic for certain applications and certain ports. By performing free tests with Wehe on your mobile device, you are participating in an IRB-approved research project at Northeastern University (led by Dr. David Choffnes) and you are helping to identify potential violations of net neutrality. Note that no conclusion can be drawn from an individual result of the type "Differentiation detected" to characterize a breach of Regulation (EU) 2015/2120 on Open Internet. As net neutrality regulations vary according to location, Wehe collects coarse-grained geolocation data (with a precision of 0.1 degrees latitude/longitude) if users explicitly opt in to providing it. Wehe never collects fine-grained geolocation information. Wehe also collects IP addresses, which are stored as truncated data so they cannot be tied to individuals. As such, all the collected data are deidentified to guarantee the protection of personal data. The deidentified data are published as open data to let third parties reproduce the conclusions of the tests carried out. Finally, Wehe uses servers located around the world, including ones hosted by Measurement Lab (M-Lab). M-Lab collects additional measurement data from clients, but does so in a way that is consistent with Wehe’s protections against collecting personal data. Note that the set of servers and hosts may change over time, but our privacy policy and data protection practices remain the same. No personal data are either transferred, or exchanged, or rented. In accordance with the General Data Protection Regulation (EU) n°2016/679, please note that you have the right to oppose, access, rectify, delete, limit or transfer your personal data.

Verdict
The clearest difference is rating: OONI Probe at 4.5 against Wehe's 4.1. OONI Probe also leads on review sentiment (58% vs 41%). Wehe's advantage is ratings volume (420 vs 84) and iOS requirement (12.0 vs 14.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
OONI Probe holds the better App Store score, 4.5 against 4.1. That said, the two scores are not equally well evidenced: Wehe has 420 ratings behind it against 84, so its average is the more settled of the two. Written reviews point the same way: 58% of OONI Probe's written reviews are positive against 41% of Wehe's.
OONI Probe ships an update every 2 months, Wehe every 5 weeks. The most recent releases landed on September 22, 2026 and September 23, 2026 respectively.
