Download COVID Alert NJ from the iPhone App Store or Android Google Play Store today.

COVID Alert NJ is the New Jeresy's exposure notification app that alerts users if they have been exposed to someone who has tested positive for COVID-19. The app is free, easy to use, and protects the user's privacy and data whlie providing them with critical helath information. COVID Alert NJ uses Bluetooth proximity detection without accessing or collecting any GPS location data.

How It Works

Step 1
Download the free app from the iPhone App Store or Android Google Play Store.

Step 2
Once you decide to opt in for exposure notifications, your phone will anonymously share random Bluetooth keys that change every 10-20 minutes with other phones that are using the app and are in close proximity.

Step 3
Your phone and others using the app will exchange those Bluetooth keys in the background, without draining your phone's battery or data. This is a passive process that begins once you enable notifications, and functions without the app open.

Step 4
When app users test positive for COVID-19 and they decide to share the results through the app by entering a special 6 digit code, the list of random keys they have encountered in the past 14 days is checked against theirs.

Step 5
If there is a match, the app alerts the other individual they are a close contact, encourages them to get tested for COVID-19 and to self-quarantine.
