Howdy HN, I'm part of a small team in Seattle, WA that worked over the last 2 weeks to put together a contact tracing app that is focused on user privacy. The app works by recording your location history for a 3 week period and then comparing it against the location history of reported COVID-19 infections. All of the comparisons happen on your phone, so your location history never leaves your device unless you report an infection.

Our app is ready to launch in the Google and Apple app stores, but they have changed their requirements for anything COVID related, which means we have to partner with a recognized institution. We are working as quickly as possible to find a partner. If anyone has a promising contact that might be able to help, please let me know!

Happy to answer any questions as well.
