Organizers running precincts for Iowa’s first-in-the-nation presidential caucuses didn’t get to test the mobile app they were to use to report results until just hours before voting began.

Iowa party officials had said they would not be sending the new mobile app to precinct chairs for downloading until just before the caucuses to narrow the window for any interference. Some precinct chairs said they had trouble downloading or logging into the app and didn't use it.

As of late Monday, the Iowa Democratic Party had yet to report any results, saying they have been delayed because of “inconsistencies” in the count.

An Iowa Democratic Party manual had told caucus organizers that the app was the "preferred method" for reporting results. It listed a single phone number for those who chose to call them in from the 1,678 statewide precincts.

The manual laid out how the app would work: Organizers would log into the app using a PIN listed on their Caucus Math Worksheet when they called the meeting to order. They would enter the number of participants and the app would calculate the "viability threshold" for the site.

Organizers would then use the app to report the results of the first and final alignments, and the app would calculate the number of delegates each campaign won. Lastly, they would take a photo of the Caucus Math Worksheet with the written results as a backup.
