SlowCOVIDNC is the official COVID-19 Exposure Notification app for the North Carolina Department of Health and Human Services (NCDHHS). It allows users to know if they may have been in close contact with someone who has shared a positive COVID-19 test result through the app. Users can anonymously share a positive COVID-19 test result to help slow the spread of COVID-19.

NCDHHS created this app so that North Carolinians can do their part to protect their community and slow the spread of the virus.


Step 1: Download the SlowCOVIDNC Exposure Notification app. Enable Bluetooth and Exposure notifications.

Step 2: After opting-in to receive notifications, the app will generate an anonymous token for your device. A token is a string of random letters and numbers that is used to represent a phone for a short period of time. This ensures your privacy and security are protected. These individual tokens change every 10-20 minutes and are never linked to your identity or location.

Step 3: Through Bluetooth, your phone and the phones around you with the SlowCOVIDNC app are working in the background (without draining your battery or data) to exchange these anonymous tokens every few minutes. As a result, devices can remember how long they are near each other. Phones also record the Bluetooth signal strength of their exchanges in order to estimate how far apart they are.

Step 4: SlowCOVIDNC periodically downloads tokens from the server that have been uploaded from the devices of users who have tested positive. Your phone then uses its records of the signal strength and duration of exposures with those tokens to conduct a risk calculation and determine if you have met a threshold for notification.

Step 5: If you have tested positive for COVID-19, you may obtain your PIN from your local public health department and submit that into the app. This voluntary and anonymous reporting notifies others who have downloaded the app and may have been in close contact with you in the last 14 days that they might be at risk.


Using SlowCOVIDNC is entirely voluntary, and you can enable or disable it at any time. When using SlowCOVIDNC, your privacy will be protected. Tokens will collect and share date, time, signal strength and duration of proximity. No location data or personally identifiable data will ever be collected or stored.

By enabling Bluetooth and Exposure Notifications, you can anonymously share a positive COVID-19 test result to help slow the spread of COVID-19. You may also be notified if you have been in close contact with someone who has shared a positive COVID-19 test result.

Good idea until it hangs up

It’s very reassuring to see a result stating that there has been no exposure. It’s important to me since I was required to go to the office every day rather than work from home. However…
The app works very well for a while, anywhere from one to five weeks, then it stops checking. I know the app is working because the stats continue to change, but no checks occur. I have waited as long as eight days for it to pick back up (remember, I go to work five days a week),but once it hangs up the only remedy is to export the exposure log (just in case), delete the app from my iPhone, and then reinstall it. I don’t think it should require so much fuss. I thought this would be a one-time installation but I just reinstalled for the sixth or seventh time.

Good on NC DHHS

This is obviously dependent on everyone having the app and them reporting. That said, if they catch covid, if they’re a good citizen they should install it and report, but that’s pretty much locking the door after the horse has bolted, but it would be something. Also, with me living very close to the SC border who don’t have an app, I’m not so sure this will work that well. Add to that apartment/condo or townhouse living and a neighbor you have had no contact with reporting, you could get notifications because their phone is the other side of the wall, but it’s better than nothing. Realistically, the CDC should have had a national app. Why they don’t may be due to budget cuts? Who knows. Still - as I said it’s better than nothing and kudos to NC state dept of health for getting this out. Seemingly one of the few states that bothered.

Great idea but probably too few people using it

Rating it 5 stars to hopefully increase visibility, but...

I've had this app installed since it came out. But I've just now turned it off because 1. no one seems to have heard of it (so they're not using it), 2. It eats my battery, and 3. I rarely leave the house.

Even though it's a battery hog I'm not complaining about that-- I understand that it needs to use Bluetooth aggressively to do what it needs to do-- but if 99.9% of the time it's consuming battery charge while I'm at home and there's no one else around, and the rest of the time it's probably futile because most other people don't have it, then unfortunately it's not helpful. Bit of a chicken and egg problem....

Developer Response ,

Hello! Thank you for reaching out and providing feedback. The app was tested extensively for battery life by Apple and Google, however if your experience is different, we’d like to dive deeper to find out why you are seeing a drain on your battery. Please email us at NCHealthIT@dhhs.nc.gov if you would like to move forward with this. Thank you!
