The Nevada Democratic Party said Tuesday that it will not use the app at the center of the technical difficulties causing delayed results in Iowa’s caucuses.

“NV Dems can confidently say that what happened in the Iowa caucus last night will not happen in Nevada on February 22nd,” the state party’s chairman, William McCurdy II, said in a statement. “We will not be employing the same app or vendor used in the Iowa caucus.”

The app was developed by Shadow, a software company in Denver. Representatives for the firm didn’t immediately respond to a request for comment.
