View reports in the event content management system (CMS) that show how attendees use the mobile event apps. Study click and tap usage reports of attendees in the mobile event app and see counts of total and unique clicks in different sections of the event app. Preview the total installation counts per device type (iphone, ipad, Android, etc.) and download statistics onto Excel files for further analysis.
If banner ads are a big deal then the event app system can be setup to show how many times a banner was displayed and how many times it was clicked on. Monetize on the advertisement statistics by showing them to sponsors of current and future events.
