Thanks for checking us out! There is an international standard for this, DNS. Devices before 1987 are not supported (RFC 1035). With regards to device hopping, try getting a spare router and setting it up then changing the Wifi password so kids only have access to the single router. Some routers will also enforce DNS packets (so even if they modify the DNS in their phone or tablet it will not work) I agree we are not a replacement for parenting in general. We are a tool. We think parents want to be better at managing this but don't have the tools to do it. Even the best solutions available we could find require setting strict schedules or constantly being pestered to turn a site on or off. Also we provide the ability to modify how long they get access for. It defaults to 30 minutes right now, but I would suggest setting it higher if you think they will put up a fight. What I have seen (even with myself) is virtually any amount of time limit will eventually invoke the "Why am I watching this?" effect since you value the time more if you work for it. With regards to phones we have an Android app right now and are in the process of finishing our iOS app. Both platforms support installing an app that requires flashing the phone back to stock to disable it. We have tested this on both platforms but not yet enabled it since it complicates things and we are still getting what we have working. Also our apps are a VPN itself, and you cannot have multiple VPNs enabled on either platform. While we currently only use our Layer 2 control in the VPN to enforce DNS settings in the future we can do a lot more.
