To create a device use schedule:
iOS devices cannot be blocked due to operating system limitations.
The Downtime feature is available in the premium version. You may need to update your child's app to the latest version.
Additional time requests
When the daily limit is exceeded or downtime is scheduled, your child can request additional time using the app. You will get an email or push notification with the request.
When you allow additional time, your child can use the added hours anytime on the day of the request until midnight. The scheduled downtime will be ignored by the app. The hours past midnight will also be ignored. The request is one-time and does not change the pre-defined schedule.
