AudienceReport to the rescue
To meet this demand, we have created the opportunity to track and report profile data for in-app traffic as we do for browser based traffic. This is done by using device-ID’s (also called advertising identifiers), enabling us to tie in-app usage to our individual panelists. These device-ids are called IDFA (Identifier For Advertisers) on iOS devices and AAID (Android Advertising ID) on Android devices.
AudienceReport tracks across browsers and apps
With in-app tracking, you can measure the performance of your campaigns not only across desktops and mobile devices, but also across browser based traffic and in-app traffic on both desktops and mobile devices.
