I appreciate your article and don't at all agree with the previous poster's statements around too much info. The information you provided was absolutely helpful.
I'm struggling to find an app or service for my situation and, through research, feel that I'm not going to either. I have all iOS devices (shame!) and two teenage boys that we'd like to monitor. We've familiarized ourselves with the iOS settings and have enforced some of those, but they're not bullet proof. One son has managed to turn off the real-time texting that we had enabled to go to our own iOS devices. That's frustrating within itself.
Ultimately I'd like a nonintrusive way to monitor (ideally real-time) their devices AND include third party app activity - i.e., SnapChat, Instagram, etc. Some services will monitor some apps but not the app activity specifically. I want to see what they're sending and to whom, and that within itself has proven to be a challenge.
Is this possible??
