- allowed list of apps, can reduce it to just phone, imessage, and utilities like weather app
- effectively permanent downtime, just set the end time less than start time such as 3:00 am to 2:59 am (technically 1 minute of non downtime). This blocks apps except for the allowed apps
- disable installing apps from app store
- disable adding new contacts and block calls and messages not in contact list. This allows parent to control who the phone can be used to contact
- none of these settings can be changed without the screen time pin
- also configure the phone with a minor apple account and add to your family group so you can monitor and control screen time settings from your phone.
So start with a super locked down phone that can only be used to communicate with parents. This is very helpful when they start after school sports. And the phone is so locked down they don't really have any interest in it.
Later when they're older start allowing communication with friends from school. But still only phone and imessage, no other apps. This reinforces that it's a communication device, not for endless scrolling and watching videos.
