## Why It Matters  
Internet censorship and network degradation affect millions of users worldwide, yet reliable, transparent data about these issues are scarce. OONI Probe empowers individuals to collect and share empirical evidence of blocking, throttling, and performance problems directly from their devices. By aggregating measurements from a global user base, the Open Observatory of Network Interference (OONI) builds a publicly accessible dataset that researchers, journalists, and policymakers can use to monitor freedom of expression online. Its open‑source nature ensures that the methodology is auditable and that the community can contribute improvements, fostering trust and collaboration. Because the app runs on the ubiquitous platforms of iOS and Android, it reaches a broad audience, turning everyday smartphones into measurement nodes that collectively illuminate the state of the internet.

## Notable For  
- **Cross‑platform design:** One of the few censorship‑measurement tools that natively supports both iOS and Android.  
- **Frequent stable releases:** Sixteen documented stable versions between February 2025 and November 2025, demonstrating active development.  
- **Open‑source transparency:** All code is publicly available on GitHub, allowing independent verification of measurement techniques.  
- **Broad distribution:** Available through the three major Android marketplaces (Google Play, Huawei AppGallery, F‑Droid) and the Apple App Store.  
- **Community translation:** Localization contributions are coordinated via Transifex, facilitating use in many languages.
