Citizen, the most trusted public safety app in the US, has introduced SafeTrace in partnership with San Joaquin County Health Care Services to help people know if they’ve been exposed to COVID-19, and to help cities and states track potential outbreaks in an efficient, scalable way.

Get alerted when you need to get tested. - If you’ve had meaningful contact with somebody who later tests positive for COVID-19, you’ll get a notification to get tested. If you test positive, anyone you’ve been in contact with recently will be notified.

Powered by Bluetooth. - Your Bluetooth information will be used to determine nearby contact with other SafeTrace users.

Private and encrypted. - All contact tracing data is private, encrypted, and is deleted after 30 days. And, if you decide to disable SafeTrace at any time, data will be deleted within 24 hours.

I sent an email to the developers several weeks ago but no response... I will probably delete this app because it continually disables the open tracking status. I understand that you probably want me to open the app every day for some kind of usage count, but if the app is disabled and I forget to enable before I go out to run errands then it doesn’t track my movements or interactions and it’s useless to me. Otherwise, in theory, it’s nice to have some kind of tracking/interaction app on my phone.

This is the only contact tracing app available for use in California. The Google-Apple technology isn’t being adopted by our state, leaving tech-heavy Californians without a solution.

Citizen has made a simple, solid app with one function. It was easy to set up, has a great UI and seems to work great. I won’t know, of course, until myself or someone I’ve been in contact tests positive, but tight now I’m doing everything I can to get widespread adoption of this.

Simple and straightforward

This app does exactly what the framework Apple and Google created is supposed to do: Keep track of other phones you’ve been near, and if one of them reported that they’ve tested positive for COVID-19, you’ll be notified that you should be tested, too. As far as I can see, it’s the only generic contract tracing app available throughout the USA. Get it, and let’s start bringing the numbers down. Oh, and wear your mask and wash your hands!
