This site is a crowdsourced list of projects related to COVID-19 contact tracing using smartphones. The goal of contact tracing is to identify the contacts of people who have tested positive for COVID-19 and to advise them to self-quarantine. Large scale, highly accurate contact tracing could control the spread of epidemics and reduce the need for societal lockdowns.

Other list projects:

• A larger list and some additional background can be found in this google doc. Formed by the merging of Stop Covid Now's list, Corona Watch's and Mitra's. Please add projects there as well.
