Yeah this is the way for sure. The OP forgets that young users advertising their age online with an "orange vest" might not be best idea.

There's almost endless choice of legit quality native apps for kids, curated from trusted sources. These alone far exceed healthy screen time if all were downloaded. Or as you say, curated web links in a locked browser.

How much screen time should kids do anyway, it's crazy how much is available before worrying about WWW on top of their games, apps and videos.
