Po-Shen Loh creates coronavirus tracking app NOVID

NOVID was created by Po-Shen Loh, a professor in CMU’s Department of Mathematical Sciences in the Mellon College of Science. He and nearly two dozen students and alumni from across the university’s seven schools and colleges have been working on NOVID since March. Loh’s social enterprise, Expii, initially funded the app, which is available on Android and IOS for free.

NOVID uses a smartphone’s Bluetooth and ultrasound sensors to accurately and anonymously measure how far away other NOVID users are from you, as well as how long you’ve interacted with them.
