ContactApp contact tracker

ContactApp was created to help people understand what kinds of behaviors carry the most risk of exposure to disease and practice social distancing better. It uses the Bluetooth radio built into your phone to track your proximity to other people, and provides an "exposure score" to help you understand which places most contribute to your risk.

ContactApp records only the number of people around you, and does not collect any private information

ContactApp is open source! You can see the source code here: https://github.com/nathanww/ContactApp
