Care19 Alert was the first exposure notification app to connect with the National Key Server provided by the Association of Public Health Laboratories (APHL). Use of this server allows different states’ apps to communicate with each other. Care19 Alert was launched in conjunction with Care19 Diary, developed by ProudCrowd. Care19 Diary allows users to record their activity throughout the day by attaching their location information to a random ID. Users can categorixe their trips into categories like work or groceries. The ID contains no personal information, only location data. If a user tests positive, they may share their Diary information with the Department of Health to help map the spread of Covid-19.
Care19 Alert is operable in North Dakota, South Dakota, and Wyoming
