NOVID is the first completely anonymous COVID-19 contact tracing app published in the USA which uses no personal information: no GPS, no phone number, no email.

This demo showcases NOVID's ability to utilize ultrasound to provide extremely accurate measurements of interaction distance, overcoming the known inaccuracies of Bluetooth. The team is led by Carnegie Mellon University professor and internationally renowned mathematician, Po-Shen Loh.

NOVID provides an anonymous alternative to keeping you safe during these uncertain times, by providing anonymous information about outbreak spread that keeps you in control.
