If you're a parent or grandparent, you know the struggle to keep the kids from getting into things they shouldn't online. We've talked before about filtering your entire network using OpenDNS, or Windows' Family Safety features, but those don't cover everything.
OpenDNS only deals with websites, not apps or YouTube videos, while Windows' parental controls only apply to Windows and other Microsoft products. When you have a whole range of gadgets at home, including video game consoles and streaming media gadgets, each with its own parental controls, or no parental controls, trying to get everything set correctly is enough to drive you crazy. However, there might be a solution.
That solution is a small white cube called Circle from a company called Circle which is, interestingly, supported by Disney. It connects to your Wi-Fi network and provides a single set of parental controls for every gadget that's on the same network. You just have to tell Circle which gadgets your kids use, and you can set what they can see, what they can download and where they can go.
You can use the presets for certain age groups (pre-K, Kid, Teen) or customize your own with specific blocking categories or specific apps and sites. Whatever you set will work across any gadget, from tablets to video game consoles.
