I've had iPhones since the first iPhone in 2007. Over the years, I've obviously added tons and tons of new contacts. Does anyone know of a way to check, for instance, the last time I've used a contact in any way in order to help me clean out all the unused contacts and slim my contacts list? This is not limited to iOS 8, of course, since contacts are synced via iCloud, any program running on a Mac would work just as well I imagine. We tend to only ever ADD contacts but rarely delete any of them. It'd be nice to be able to scroll through the list and only see people I care about today versus having absolutely everyone in there I ever met and added to my phone. Thanks!
