We have a 80+ iPads out in public areas for kids from 4-12 to use. We have them set up and managed through Apple Configurator, complete with about 30 apps on them. Most of the apps loaded are purchased and we're looking to find an app that can show us what apps are used and how much. This is to inform our purchasing decisions, etc. I've been looking all over and cannot find anything in this space. I understand iOS makes this a difficult task. Impossible though? Anyone have suggestions? Thank you in advance!
