Which app, developed at Carnegie Mellon University, demonstrated the dependency on public adoption?

Answer

Novid app

The Novid app serves as a specific case study illustrating the real-world operational hurdles faced by contact tracing tools. Developed at Carnegie Mellon University, the Novid app was technically designed to be sound, providing alerts based on proximity data while explicitly avoiding the collection of any location data to maintain user privacy. However, its technical merit alone did not guarantee success; its effectiveness was entirely contingent upon achieving a critical mass of public adoption. If only a small percentage of the community installed and actively used the application, its epidemiological impact, regardless of its excellent underlying algorithm, would be significantly diminished.
