After the chaos of the Iowa caucus, the Nevada Democratic party appears to be trying to avoid a similar debacle. The Iowa Democratic Party reportedly paid more than $60,000 for a vote-reporting app that was supposed to be used to communicate information from the 1,700 caucus sites to the state party. But on the evening of the caucus, the Iowa Democratic Party made a statement announcing that it found "inconsistencies in the reporting of three sets of results" and said that it would perform "quality checks" while precincts called the party hotline to report results instead.

The debacle led Nevada's Democratic Party to change plans.

For the Nevada caucus on February 22, "We are not using an app, we are not using something you can download on your phone," Nevada Democrats executive director Alana Mounce told The New York Times. Caucus organizers will instead input numbers of caucus-goers, and how many supporters each candidate has, into the Caucus Calculator on iPads provided by the party. The numbers will be added to Google Forms and paper worksheets, which caucus organizers will photograph as an added fail-safe.

The party released a 143-slide training deck online that address each step of the caucuses, including how to use iPads where precincts will report voting data, The New York Times reported.
