Solution: don't give your kids the device. Put up a computer in the family room like it's 1998. Perfect, now little Timmy can do his homework. And if he looks up "boobies", he won't be able to sneak it past you!

The best part? This is cheaper and easier. You're literally doing less. Locking down a smartphone is hard? Great, so don't do that. Problem solved, you're welcome, I'll send you my invoice.
