Asking for ideas on alternative for google's family link software. Family link is great because it is baked into the OS well and does not allow user to block, remove, bypass... unlike some other app I tried before. Teenagers who is well versed with computer language and coding can bypass, stop the app from working. Means the app is still there, but they have managed to continue their game, connect to internet, etc... all except google's family link.

But now I am passing down a phone which has China rom and family link won't install properly. Any susggestion of free app similar to family link please?

i think the most effective is to use router setting to block/allow which app/sites or you can setup Adguard DNS with your router for more personalize setting.

using this is more effective for home network as the only to modify this if ur child know the password as u know all app in phone can be easily force stop in phone setting

downside is, u can do nothing if ur kids is using mobile data

Thank you so much. I have switched from Asus RT-AX55 to Dlink Eagle Pro since yesterday. Asus cannot block those https sites. So if they play any games accessing https sites, they hit home run.
Dlink's parental control seems better, as the instruction suggest we key in the keyword and it will block all sites with the keyword, such as roblox. Just got it running, not yet set anything.

But these god damn games where they let you watch ads and then unlock or give you rewards, those ads contain 18+ stuff. Or it contains an ad for online dating/viewing, where there's 18+ porno stuff in it. And the game is rated for 13 and below.
