Great question. For set-it-and-forget-it parental controls at the network level, I’m a big fan of the Gryphon Guardian. Its app is super intuitive for filtering content and setting screen time limits. Eero mesh systems are also a solid, user-friendly choice, though some advanced features require a subscription.
Pro tip: Router controls are fantastic for home Wi-Fi, but they don’t work once your kids switch to cellular data. That’s why I layer router rules with a dedicated app. For mobile management, Parentaler is awesome for setting device-specific rules and tracking location when they’re out and about.
