Really curious about how you're doing this. Did something change with iOS 9 that allows this kind of system level access?
Either way, awesome and very needed.
We're really excited to tell you about Kidslox Parental Controls for iOS and Android.
With ever increasing use of mobile and tablet devices in the home, we've created a cross-platform app to make the lives of parents easier and those of children safer and healthier. Once installed, parents can setup restrictions and apply them remotely to their family's devices using WiFi or 3G/4G.
Please do visit our website / app stores for more information.
Joel, Kidslox
