"Parental Control" app or setting for work I'm searching for an app or settings that will allow only 2 applications to be used on an android tablet. 

They would use android and a web dashboard on chrome, on chrome they would get a certain link automatically loaded and I would try to make it impossible to go to other pages. 

I want to only allow those two apps to be used. 

I've looked in to kiosk mode ( but thats single app usage)
I've tried COSU but that also not a solution.
And parental control apps, but they show advertisement which I can't allow on the work floor.
Well there is no such kind of application for parenting control for Android. There are a lot in different applications in Play Store but doesn’t seem anything akin to your requisite. 

You can endeavor NORTON FAMILY PREMIER and check if that’s worth.
