How to Get Started

Carry On

The app will run in the background and you'll receive a notice if you've been exposed. That's it.

Yes, you can help stop COVID-19. Here's how: 

To understand how our app works, it's important to understand how a virus spreads. 

How a Virus Spreads

Without social distancing, wearing face masks, quarantine, or other measures, a virus like COVID-19 can spread rapidly through the population. This is how we got to millions of infections globally, so quickly.


Intervention Stops the Spread

The Covid Watch app allows people to receive completely private notifications on their phone whenever they may have been in close contact with a contagious person. With information from the app, people can start to take extra precautions and self-isolate even before their symptoms appear, preventing further spread of the virus.



Frequently Asked Questions

For additional information, reference our complete FAQ

Where is Covid Watch available?

As of September 2020, Covid Watch is available for the University of Arizona and Northern Arizona University as part of a phased rollout in the state of Arizona in partnership with the Arizona Department of Health Services. Coming soon to additional regions and jurisdictions. 

How do I install the Covid Watch app on my phone?

First, download Covid Watch from Google Play or the App Store. Then, open the app and select your region. A short explanation of the app will be presented to you. Once you review the introductory screens, Covid Watch will ask for permission to run in the background, just like other apps do on your phone now. Ensure that Bluetooth is activated, as the app requires it. Approve the app to run in the background, and you're all set up. There’s nothing else you need to do to make Covid Watch work on your phone.

Covid Watch works on newer smartphone devices. Compatible with iPhone, supported on iOS 13.5 & 13.6. Supported on Android Version 6 (API 23) or above.

How do exposure notifications help?

Exposure notifications can help alert app users of potential exposure, even before they may experience symptoms, so that they can act quickly and take the appropriate next steps to protect others around them and help contain the spread of COVID-19. Notifications occur when your app anonymously downloads fresh data from the server, as opposed to the server pushing out information to you.

What are you doing to protect my data?

No personally identifiable information is ever tracked or stored in Covid Watch. In fact, Covid Watch uses technology that sets the standard for digital rights and privacy protection in COVID-19 exposure alert apps, which is now supported by the American Civil Liberties Union and the Electronic Frontier Foundation.

Bring Covid Watch to Your Community

We are working with public health authorities and higher education institutions to bring Covid Watch to additional states in the U.S. and to countries worldwide.
