Why one US state will have two coronavirus tracing apps

The news: North Dakota was one of the first American states to launch a coronavirus contact tracing app, in April.

First mover: Before North Dakota began to reopen some services on May 1, the state released an app called Care19.

“This is an opportunity for North Dakotans to be leaders in the worldwide response to covid-19,” Governor Doug Burgum said at the time of release. “Our goal is for at least 50,000 North Dakotans to download the app.”
