Tablets....and content

​I have a blocker on my computer for content and site restrictions... but is there anything for a tablet? I was mortified when I was on one of the APP markets looking up an app to install on my daughters tablet when I saw an app called "Hot teen sex videos" with a lovely picture there on the screen. I was mortified and glad I had seen it and not my children. Anyone know if there is a way to block anything on a tablet? I want them to have their own freedom to find their own games but NOT at the cost of seeing smutt!
