I don’t think this is only a kids issue.
A lot of adults need this too. The addictive apps are very well designed, while most blockers are either too easy to ignore or too annoying to keep using.
I built a small iOS blocker because I had the same problem. Making it strict enough to actually work without making people hate it is the main challenge.
Toast notifications were the big mistake. Also badges. In my perfect world, the only thing to retain the ability to keep messages alerting the user that someone tried to contact them would be voicemail, subject to the same spam laws as everything else.
As an adult, who despises all those apps, I don't want to grant government the power to make that decision for me.
If we afford the same protections to adults, we don't need age verification either. Just a thought.
On the radio I heard a reporter talking about things China does during school exams. Apparently all schools have exams at the same time and during that period, social media shuts down at night. I forget the exact hours (10pm - 6am maybe). I'm starting to think that would be a great policy in general for everybody.
I think they also said AI companies go offline during exam hours, but I may have got that wrong.
