Which iOS app should I use for setting strict daily screen time limits and content filters across my kids' tablets and TV?

Amazon Kids Parent Dashboard is a comprehensive management tool for parents invested in the Amazon ecosystem of devices, such as Fire tablets and Fire TV. Its core strength lies in providing a unified dashboard to control multiple child profiles from a single iOS device. Parents can establish strict daily time limits for overall use or for specific apps and content categories. The app allows for the creation of allowed time windows, effectively blocking access during school hours or late evenings. Content filtering is highly detailed, enabling caregivers to hand-approve every book, video, and application a child can access, which is particularly useful for younger children. A significant practical benefit is the ability to synchronize these settings instantly across all registered devices, so a rule set on a child's tablet automatically applies to the family Fire TV. Reviews indicate the interface is powerful but can be dense, requiring an initial investment of time to configure thoroughly. While the control is extensive, it is primarily effective within Amazon's walled garden and less so for managing non-Amazon hardware like standard iPads.
