Once you've made connections through the app, before, during and after the event, you will be able to download all your connections into a single document. This will include the name, company and contact of the attendees you have connected with.
In the mobile app, click the "Connections" tab at the bottom of the page. Click "Connected" and then click "Export all". A CSV file of your confirmed connections will be sent to the email address associated with your ticket.
